Processor Support: Present and Future

Initially, there was a bit of confusion about support for Zen 3 processors (upcoming Ryzen ) on B and X motherboards with AMD announcing that they wouldn’t be supporting the older platforms. However, in a welcome turnaround, they have since officially announced that they will allow motherboard manufacturers, i.e., us, to decide!

Note - MSI always intended to add support for Zen 3 to as many B and X motherboards as possible; this hasn’t changed. A beta BIOS will be made available for eligible motherboards after the release of Zen 3.

While older B and X motherboards will require a beta BIOS update to use Zen 3 processors, the B and X platforms will officially support them. So, here’s what processor support will look like across all AM4 platforms:

  • Beta BIOS updates will open up Zen 3 support for B and X

Lightning PCIe and M.2 Gen 4 Capabilities: Ushering in the Future Together

The latest connectivity standard, PCIe Gen , is picking up steam – offering blazing speeds for those who need the best in storage and graphics devices of the future. Motherboards that support this new standard will allow you to keep up with a new era of graphics cards, storage devices, networking devices, and so much more. As expected, both MSI B and X motherboards support PCIe !



AMD B chipset


Bringing double the speed and bandwidth over the previous PCIe standard, PCIe is all set to power a new era of peripheral devices without holding them back in the slightest. The whopping 64 GB/s bandwidth of PCIe will be a godsend for professional workloads – making them faster and easier.

There is already a new generation of M.2 storage devices in the market today that reach truly incredible read and write speeds. With sequential read speeds of up to MB/s, these new-gen devices can easily handle huge chunks of data without breaking a sweat. They’re an ideal choice for professionals working with huge raw files and footage – allowing them to get more done with a substantially faster storage solution.

Next-Gen Networking and Storage Solutions

Professionals needing to store large amounts of data will usually rely on a NAS on an internal network. But transferring large data chunks can be a painfully slow task with the older generation of networking hardware. Moreover, if you want to store more data on faster storage devices, you’ll need additional M.2 slots to ensure that you can add more storage when needed without any hassle.

Many MSI B motherboards come equipped with both faster networking capabilities as well as more M.2 slots compared to their B counterparts – making them an ideal choice for professionals who need an upgrade over the best that the B platform can offer.

What Chipset Should You Pick?

Who should upgrade to (or keep) a B/X Motherboard?

AMD has officially allowed manufacturers to support Zen 3 processors on B motherboards with a BIOS update. If your only reason for an upgrade is future processor compatibility, it's better to stick with a B motherboard for now.

We can't speak to whether all B and X motherboards in the market will get an update to support AMD's new processors. MSI will be updating as many B and X motherboards as possible so users can enjoy the latest generation of Ryzen processors without changing their motherboard. You can expect more details about this in an announcement later this year!

However, MSI's B motherboards add a ton of features to the mainstream platform, and if you care about faster storage and connectivity, better overclocking stability, and more robust power solutions, all at relatively affordable price ranges – grabbing a B motherboard is an excellent choice.

Who Should Upgrade to B?

If any of the following rings true for you, then yes, an upgrade to an MSI B motherboard makes total sense:

  • You want access to the latest PCIe standard to ensure that you can use lightning-fast, next-gen peripherals, and graphics devices.
  • You need access to incredible read and write speeds offered by M.2 Gen 4 NVMe SSDs for professional work.
  • You want an affordable motherboard that can easily harness the power of both current and future high-end Ryzen processors.
  • You want to run higher-frequency memory to improve performance on Ryzen processors.
  • You're looking for built-in support for Wi-Fi 6 and Gigabit LAN.
  • You want access to high-end motherboards, and many premium features launching on AMD’s mainstream platform for the very first time.

Every MSI B motherboard has been carefully engineered to handle the astounding power of both current and future AMD Ryzen CPUs. So, if you’re looking to get the most out of Ryzen processors, the answer to whether you need to upgrade is easy. Yes.

Who Should Upgrade to the X Platform?

Some professionals may need even more power and extensibility than what the B platform can offer. For such professionals, MSI’s X motherboards are the ideal choice. If any of the following apply to you, the X platform is a better choice:

  • You use more than 4 USB devices
  • You use more than 6 SATA devices
  • You use more than 3 Gen 4 M.2 SSDs

AMD B vs X Motherboards: Which Should You Buy?

AMD’s much-awaited B chipsets have finally arrived replacing the B chipset from two years ago. The B chipset carries over much of the higher-end X features making it a viable option if you are in the market for a motherboard to use with your Ryzen processor. So, the question arises, B vs. X which should you buy? In this article, we will discuss the significant differences and find out which of these motherboards is better for you.

Differences between B and X Motherboards:

The differences at a glance:

Chipset PCIe connectivity: PCIe is the next generation of connectivity between the motherboard’s different components. Whereas X motherboards make use of PCIe , the B motherboard’s use of PCIe connectivity is quite limited (more info below). Though, the B limited use of PCIe is a step up from B motherboards which have no PCIe connectivity. 

Performance and Overclocking: The X series of motherboards come equipped with a higher number of Voltage Regulator Modules or VRMs for better and more regulated power delivery to your CPU, allowing for more stable overclocking and better performance when compared to B motherboards.

Nvidia SLI and NVLink Support: If you are looking for a dual GPU configuration, you will need a motherboard that supports Nvidia’s SLI or NVLink technology. Most X motherboards will support them while only the more premium B offerings have the option.

Price: X motherboards are the more premium option and offer more features than B making them significantly more expensive.

10 Gbps USB and SATA connectivity: The B chipset supports much less 10 Gbps high-speed USB lanes and SATA ports than the X, resulting in much fewer USB ports when compared to the X But this is not really a deal-breaker, as USB ports are perfectly fine for your peripherals.

The differences in more detail:

PCIe Support

PCIe support will enable a maximum bandwidth of 16 GT/s per lane over the 8 GT/s of the older PCIe , which means that it will require half the number of lanes for running your GPU or SSD. The advantage is that there will be free lanes for extra SSD slots and even Nvidia’s SLI or NVLink certification. The main difference is that the B chipset connects to the processor via a four-lane PCIe connection while the X uses PCIe This allows AMD to add 16 PCIe lanes to the X chipset while the B has none.

However, for the B chipset, PCIe connectivity will run on the CPU directly to the primary PCIex16 and M.2 slots meaning that B motherboards will support PCIe for up to two devices, unlike B motherboards. The manufacturer can use these PCIe lanes to provide a variety of features like extra PCIe M.2 slots which makes the X a more appealing buy but at a higher price.

Connectivity

Continuing from the difference in the number of PCIe lanes from the chipset, the X allows for more 8 USB () 10 Gbps ports than the B, meaning that most ports on your PC can make use of faster data transfer speeds when compared to the two on the B Also, an additional eight reconfigurable SATA ports on the X are excellent if you are looking for a motherboard with a more significant number of storage options, but keep in mind that this will need to be configured by the manufacturer, so check the amount of SATA ports before purchasing.

VRM Power Phases

The VRMs of your motherboard regulates the amount of power delivered to your CPU by splitting the total energy. The more VRMs, the better since there is more control over the exact power delivered and reduces the load on the individual VRMs, reducing the possibility of failure. X motherboards always have a higher number of VRMs than their B counterparts, although some premium B boards provide more than the usual. This allows you to overclock even the more powerful processors like Ryzen 9 while maintaining a stable system allowing you to squeeze out more performance.

Supported Chipsets:

Before you decide to go out and buy these motherboards for your processor, you need to make sure that your processor is supported. Here is a comprehensive list of processors that have support on both systems:

X

  1. Zen 3 Ryzen Processors
  2. 3rd Gen Ryzen Processors
  3. 3rd Gen Ryzen Processors with Integrated Graphics
  4. 2nd Gen Ryzen Processors
  5. 2nd Gen Ryzen Processors with Integrated Graphics
  6. 1st Gen Ryzen Processors (Only AF models)

B

  1. Zen 3 Ryzen Processors
  2. 3rd Gen Ryzen Processors
  3. 3rd Gen Ryzen Processors with Integrated Graphics

Ryzen Support

Both motherboards will support the upcoming 4th Generation of Ryzen processors allowing for reasonable future-proofing, and although the older B and X will support these chipsets, it will involve a flashing process making them incompatible with current processors. Now that you know the differences between both chipsets and the CPU support for each, head on below to find out what is best for you.

Who is the AMD B chipset for?

ASUS ROG Strix BF Gaming AMD AM4 Zen 3 Ryzen & 3rd Gen Ryzen ATX Gaming Motherboard (PCIe , Gb LAN, BIOS Flashback, HDMI , Addressable Gen 2 RGB Header and Aura Sync)

You should buy a B motherboard if you are looking for a cheaper X alternative with better VRMs than B motherboards, PCIe support, and future-proofing at a lower price point.

Why you should buy a B motherboard:

Cheaper Yet Very Capable X Alternative

If you have a budget of about $ or less for a motherboard, the B is most likely the best choice for you. The B chipset offers excellent value for your build as it manages to port over most of the features from the X at a considerably lower price when compared to more premium X boards. So unless you need the extra features and slightly better VRMs of X, you should choose the B instead.

Performance/Overclocking 

B motherboards will provide the best results when paired with processors like the Ryzen 5 to 7 series and you can overclock them fairly well without running into stability issues. For the top-of-the-line processors like the Ryzen 9 series, which draw more power, it is better to stick with the X, especially if you plan on overclocking for better stability and performance.

PCIe Support

As stated above, B motherboards are limited when it comes to PCIe , but the fact of the matter is that it does support PCIe , meaning that you will get at least 1 PCIe M.2 slot and some USB ports for faster connectivity. For example, if you want to utilize a PCIe M.2 SDD, a B motherboard would be the better choice, rather than a B motherboard. 

CPUs we recommend to use with B Motherboards:

  • Ryzen 7 X
  • Ryzen 5 XT
  • Ryzen 5 X
  • Ryzen 5
  • Ryzen 5 X
  • Ryzen 5

Who is the AMD X chipset for?

ASUS AM4 TUF Gaming XPlus (Wi-Fi) AM4 Zen 3 Ryzen & 3rd Gen Ryzen ATX Motherboard with PCIe , Dual M.2, 12+2 with Dr. MOS Power Stage

You should buy an X motherboard if you are looking for a top of the line motherboard to pair with your Ryzen 7 or 9 processor that has better VRMs, extensive PCIe support, and other features when compared to the B motherboards.

Why you should buy an X motherboard:

Higher Core Count CPUs and Overclocking

X boards with superior power delivery in the form of a higher number of VRMs will easily be able to overclock even the most power-hungry processors like the Ryzen 9 series with relatively better stability. Also, many X motherboards have better quality VRMs and cooling solutions for more reliability and longevity. If you are looking to get a Ryzen 7 or 9 CPU, or are just an enthusiast looking to squeeze out the maximum performance from such processors, we recommend going with the X for the best results.

Extensive PCIe and USB Support and Overall Connectivity:

X motherboards have 16 PCIe general purpose lanes. With this, motherboard manufacturers can repurpose some of those lanes to provide a host of different features like extra PCIe M.2 SSD slots for faster storage.

X boards also manage to have a more significant number of high-speed USB ports and faster internet options like 10 GiB ethernet.  Which for example is especially helpful if you need a PC that can hook up to several devices and transfer data quickly or if you want to work off a NAS.

CPUs we recommend to use with X Motherboards:

  • Ryzen 9 X
  • Ryzen 9 XT
  • Ryzen 9 X
  • Ryzen 7 XT
  • Ryzen 7 X
  • Ryzen 7 X

Closing thoughts:

The B and X are excellent choices for Ryzen CPUs as they provide the right amount of features like PCIe and future CPU compatibility making these a good investment for your PC, especially if you are looking for upgrading to the next generation Zen 3 processors soon.

We recommend going with the B if you are looking to use a processor like the Ryzen 5 with a decent level of overclocking and looking to use your desktop for a typical use case. You can use the money saved by going with the B to upgrade parts of your build like the SSD or GPU, which will give you a more significant performance upgrade over the X

The X, on the other hand, is an excellent option for those looking to use the more powerful Ryzen processors like the Ryzen 9 series and enthusiasts looking to gain the maximum from their PC. If you need the extra high-speed ports, additional storage connections, or faster network connectivity, X boards have specialized versions to suit your needs without compromising on the performance of other components. The X works best with builds where the budget is not a constraint and proves to be highly reliable.

Are the Extra Features of X Worth It? Why Does B Sometimes Cost More?


Comparing the B and X chipset differences and what they mean for youIt can be a confusing choice, but we'll break it down in simple terms for anyone to understand

Last Updated: January 29,

With the release of AMD's mid-range B motherboard chipset, choosing the right AMD motherboard for a new gaming or workstation computer became more confusing than it already was in the first place, with the B range offering both cheap budget models and high-end options priced well into X territory. 

Here we'll simplify the X vs B decision by looking at the main differences between these two cutting-edge AMD chipsets, and what they actually mean to you in practice as a gamer or power user. After reading you'll hopefully find it much easier to choose the best motherboard for a Ryzen or Ryzen build.

The new B chipset not only competes with its lower-cost predecessor (B) but also with the high-end enthusiast X chipset, as many B boards are priced around the same or higher than cheaper X models. There are certain differences between the two chipsets which we'll get to below, but if you're strapped for time and just want the overall gist of B vs X, in general either chipset is just fine for building a great modern AMD gaming/work PC, even if using the fastest AMD CPUs on the market like a Ryzen 7 or 9. 



Building a Budget PC? B vs B

For most, since the chipsets are similar overall, choosing between B and X comes down to comparing specific models and what they offer for the price. However, for certain users, the actual chipset differences may be a factor. X is the slightly more advanced, flexible platform, but its benefits over the B chipset (which some call a watered-down X) aren't huge, and only really benefit more advanced power users (non gamers) who want to either:

  • Run multiple next-gen PCIe Gen4 SSDs (PCIe Gen 4 is not important for gaming)
  • Connect a higher than average amount of storage drives (X generally have more SATA ports)
  • Do extreme CPU overclocking (X has the best high-end VRMs)
  • Have access to extreme networking speeds (ie 5G or 10G LAN ports)
  • Run multiple GPUs for high-end workstation purposes

Simply put, if you have to ask whether or not X is worth it, or if you're building a PC mainly for gaming, chances are you won't have much (if any) need for X, and should probably just buy a B and save that money for other components like your CPU or GPU. Oh, and keep in mind if you're building with a Ryzen CPU like the X, X, X, or X, no matter whether you buy X or B there is a chance you may need to update the BIOS for Ryzen  to work. It's easy to do, especially if you buy a board that has a BIOS flash button that allows you to update the BIOS without needing to have a CPU installed. 

Eventually, and perhaps even by the time you read this, all/most B and X models should come already shipped with an updated BIOS that will boot up with Ryzen out of the box, and therefore you won't need to update the BIOS yourself. But for now in early , keep in mind you may still need to update the BIOS. Anyway, if you want to know all the differences between B and X and what they mean in practical terms with the complex jargon and enthusiast speak toned down to a minimum, let's break it all down.



B vs X Prices (General Comparison)

First let's look at the pricing overlap of B compared to X motherboards, showing the former sometimes being more expensive than the latter. In other words, certain B models will set you back more money than some X models, hence the confusion surrounding X vs B

The old simple rationale of "buy B if on a budget" and "buy X for high end builds"? B has crashed that party, with B models ranging from under $ all the way up to $, meaning that B can make sense for either budget builders or performance-perfectionist enthusiasts. To exemplify the now more-muddled landscape of AMD motherboards, here are the more expensive/premium B motherboards over $ US which square off against X competition.

Note: Prices are just estimates at the time of writing.

And please note the X prices are just mere estimates of what you can expect to pay on the market right now. But yeah, the overlap in pricing between B and X boards is confusing, and the now common question of whether you should buy a B or X motherboard is a legitimately good one. As already mentioned, and as is par for the course when it comes to almost any tech purchase, the answer is those same 2 immortal words: it depends.



Differences Between the B and X Chipset

Due to the price overlaps of B and X models, choosing between them is largely a matter of comparing specific models for their price, features, and quality, etc. Many general consumers will automatically assume that X is better than B though, based on previous chipset generations where there was a clear separation of budget and high-end chipsets (B and X for instance). But is their assumption correct?

Technically, X is the slightly superior chipset, and can offer more overall features, connectivity, and flexibility than a B can. That doesn't mean you should buy an X over a B though, as "high-end" B boards can be just as (if not better) than a competing X Besides, a good B can offer absolutely everything you'd ever need; X boards aren't going to offer tangible benefits to most users. If you're curious about the advantages of buying a X, these are the overall technical differences between the B and X chipsets:

  • X Supports Dual PCIe M.2 Slots: B motherboards can support multiple M.2 SSDs, but only one of those slots will be PCIe compatible (with just one exception; the Gigabyte B Aorus Master does have dual PCIe M.2 slots) with the 2nd slot running up to PCIe speeds. Certain X motherboards do have dual PCIe M.2 slots, but this is an extreme feature that's unnecessary for the majority as the chances you'll be buying a single PCIe Gen4 SSD is quite low these days due to cost (let alone buying 2).
  • X Supports Multiple PCIe PCIe Slots: On both X and B, the main PCIe x16 slot (full length slot for graphics cards) does support PCIe But with secondary PCIe slots, whether full-length x16 slots (for GPU) or smaller x8/x4/x1 slots (for expansion cards), those will be PCIe on B boards but may be PCIe on X (depending on the model). Not a biggie as not many people use these extra slots anyway, nor run devices that would benefit from PCIe Gen4 in the first place.

  • X Has More PCIe Lanes: Not to be confused with the PCIe slots to connect SSDs and GPUs/other cards, X has more PCIe lanes (as in, connections) available on the CPU, and also uses PCIe lanes to link the CPU and the chipset (on B this chipset link uses PCIe lanes). This essentially means X has faster and more flexible Input/Output with multiple connected devices. If you're more advanced and wondering how many more PCIe lanes X gives you (say if building a SLI/NVLink PC build where lanes can be important), a 3rd gen Ryzen CPU gives you 24 PCIe lanes on the CPU and with a X all 24 can be used (16 for GPU, 4 for storage, 4 for chipset link) while 20 can be used with a B (16 for GPU, 4 for storage).

  • X Can Support 5G and 10G LAN: B motherboards only have 1G or G LAN ports, whereas some X boards can include insanely-fast 5G and/or 10G LAN ports. Not an issue for most people though, as 1G LAN is more than fast enough for the majority of situations (gaming included).

  • X Supports Ryzen Series APUs: B motherboards do not support the most recent AMD APUs (Ryzen 3 G and Ryzen 5 G). X motherboards do, though that's hardly going to matter to many out there as the chances of combining the high-end X platform with a budget APU are slim.
  • X Supports Ryzen CPUs: B does not support the previous generation of Ryzen processors ( series, ie the X), but X does. Again, this won't matter to the far majority who will be pairing an X with a new Ryzen or processor.
  • X Has (Built-in) Onboard Cooling: Almost all X motherboards have a small built-in chipset fan to help keep the board cool, whereas B boards do not have a chipset fan as they have lower power consumption and generate less heat. If you're wondering what this means exactly, we'll discuss this next.
  • X Can Support More SATA and USB Gen 2 Ports: How many more depends on the specific model in question, but X allows for more of these ports to connect more devices. Like pretty much all of these differences between B and X, this isn't going to matter to most people, but is worth mentioning for certain use cases.

Why Do X Motherboards Have Fans?

Since X motherboards have more PCIe lanes (from both the processor and the chipset; B only has PCIe via the processor), the chipset consumes more power than B and therefore has the potential to generate a bit more heat. That's why all X motherboards with the exception of a single anomaly (Gigabyte X Aorus Extreme) have a small built-in fan, technically referred to as a chipset fan.

Chipset fans haven't been used on motherboards for a while, and some enthusiasts aren't too pleased with their return on X as they create the potential for a little extra noise. Small fans are louder than larger fans as they have to work harder to push the same amount of air, and their sound is a higher-pitched, "whinier" quality that can be a little annoying to some. 

The general consensus from X owners is the noise isn't noticeable over other fans in the system though, and that's if the fan even spins; in many situations the X chipset fan often sits idle, only firing up once PCB (the physical board) temperatures reach a certain threshold (such as when running multiple super-fast PCIe devices, when overclocking, etc). I'd only consider the noise a factor if you're super-picky about building a silent system.


The chipset fan on the MSI X Gaming Edge WiFi motherboard

But the other potential downside to having a chipset fan present is the extra point of failure within your system that can also be a little annoying to replace. Small chipset fans can fail, and since they're a proprietary fan you can't generally replace them yourself. Overall, unless these two things are important to you, I wouldn't factor in the chipset fan when choosing between X and B But it was worth mentioning so you get the full picture.



Is X Better for Overclocking Than B?

Moving on from the chipset fan to a more important factor if overclocking a mid to high-end CPU, or if simply running a high-end Ryzen 9 X or X at stock speeds: VRMs. Do X motherboards have better VRMS than B? If you don't know what VRMs are, see our motherboard buyer's FAQ, though it's essentially the area on the board that is responsible for keeping things cool. The better the VRM on a board, the more suitable it is for overclocking and/or running high-end CPUs. You'd assume that the higher-end enthusiast chipset (X) would have better VRMs than B, and that's true to an extent as the absolute best VRMs of any AMD board belong to high-end X models.

But here's the kicker; I'm talking the super premium, very expensive boards that just aren't worth it for the far majority, and in the mid-range board battle where premium B boards face off against budget X models, the former actually has the stronger VRMs overall. See this general B vs X VRM test by benchmark beast Steve from HardwareUnboxed (I can recommend his videos as a good, reliable source), but the gist is that you can get a sub $ (US) B like the B Tomahawk or B Aorus Pro that has better VRMs than similar-priced X boards like the X Pro4 or X Gaming Edge WiFi. Yup; slightly strange IMO, given X is supposed to be the high-end enthusiast chipset, but B is the newer chipset after all (X has been out for a fair while now) and so the bolstered VRMs do make sense.

These are just a couple examples, but there are plenty of affordable B motherboards with better VRMs than budget X motherboards. That means it's hard to recommend a budget X over a top B, as the latter gives you better cooling for the money, with an X in this price category only really making sense if you need the benefits of the X chipset (explained earlier).

Is X More Future Proof Than B?

Technically you could say yes, but generally speaking - no. Let me explain. In terms of future CPU compatibility, B and X have the same lifespan, as both chipsets will likely only support up to Zen 3 (Ryzen ) and any CPUs beyond that will probably require a new motherboard (and new CPU socket ie AM5).

But the argument for X being more "future proof" than B is the "deeper" PCIe support, as X has more PCIe slots (supports multiple PCIe Gen4 devices) and more PCIe lanes compared to B However, as mentioned, in practice this isn't important for most users.



Summary: Is X Worth It Over B (Pros of Each)

Let's recap and summarize the reason why you should choose either X or B The new kid on the block is B which replaces B, with X being AMD's high-end chipset for enthusiasts and power users wanting the most features.

Is X better than B? Technically yes. But does it matter for most people? No; the quality and features present on many B boards is more than enough for a typical PC build, even if sporting high-end components. 

B is more a watered-down X rather than a direct replacement of B, and the extra fancy features and capabilities of the X platform isn't likely to be something you're going to take advantage of now or in the future.

For example, one of the main benefits of X over B is the ability to run multiple PCIe Gen4 M.2 SSDs, but unless you're building a high-end video editing PC and investing heavy into storage, doing this is unlikely to be worth the cost.

Plus, B VRMs (cooling and overclocking ability) are on par with X, and sometimes even better (when comparing price). Many B models also look better than similar-priced X boards, and you've also got more choice if chasing affordable models that are mITX or have certain features like internal USB-C. But put simply, either B or X can serve you well for a powerful AMD Ryzen 7 or 9 build, so it really doesn't matter and as mentioned ad-nauseam it all comes down to your price range and comparing the specific models available.

Pros of B

  • Some models can be better buys than a similar-priced X (depends on your needs)
  • Some have better VRMs for similar/less cost
  • Some have better networking features for less
  • Only real choice if you want a smaller mATX motherboard as X has few Micro ATX models

  • Cheaper way to get an internal front USB Type-C header for cases like the NZXT H that have a front USB C port (X boards with USB-C front headers cost more).
  • No chipset fan on board, therefore no possibility of slight noise coming from board and no need to worry about replacing fan in future

Pros of X

  • Some models can be better buys than a similar-priced B (depends on your needs)
  • Can support multiple PCIe M.2 SSDs
  • Can offer multiple PCIe expansion slots
  • Generally have more USB Gen 2 ports
  • Only real option for 8 or more SATA ports
  • More PCIe lanes for faster overall connectivity
  • Supports Ryzen APUs (G and G)
  • Supports Ryzen CPUs (Ryzen 7 X, etc)
  • Only way to get extreme 5G or 10G LAN ports
  • Best option for extreme overclocking (remember to always use the extra 4 pin CPU connector as well as the main 8 pin)

B550 vs X570 Motherboard - Gaming

The chipsets help the motherboard in communicating and allow the motherboard to manage traffic. Besides, the chipsets recognize the compatible devices for the motherboard. If you have a motherboard, you will have a chipset with all the required latest advancements and specifications. You may have chosen the chipset according to you. But it is time to find the best chipset between the newly launched B and the old X

With the most awaited launch of the B chipset of AMD, into the market, containing upgraded specifications. The discussions arose about the comparisons of the B with the x chipset. There are many previously launched chipsets, but the X got precisely more attention of the buyers.

Many people are still confused between B and X So, for their ease, we have researched both the chipsets and compared their features. This article will provide you with a comparison of all specifications and differences between these two chipsets to decide which one has the edge over another one. Additionally, you will be able to find the best chipset.

Comparisons and Differences between B and X

1-CPU Support

You cannot use the chipsets with any of the processors. To relish the chipsets B and X, you must be having your chipset-compatible processors. AMD launched B recently for future use with Zen 3 Ryzen Processors and Ryzen Processors.

So B supports the Ryzen series and Future AMD Ryzen Desktop Processors with the Zen 3 Architecture. But, B does not support AMD Ryzen series or AMD Ryzen series with Radeon Graphics. If you are having the Ryzen processors of the new series, you will be able to avail of the recent advancements of the latest B

On the other end, the X chipset was launched before, featuring high compatibility, so it has complete support for Ryzen series Processors, Ryzen Processors with Radeon Graphics, Ryzen series 3rd Gen Processors, and Future Zen 3 Processors as well. You will not need to worry about the compatibility of X It can be used with various processors.

2-VRM Power Phases

VRM is the Voltage Regulator Module. The purpose of VRMS is to regulate the voltages and prevent the chipsets from an increased voltage level. They keep the voltage at optimum levels, and it is valuable for the overclocking of CPU and GPU. In VRM, X is the conqueror, as X has more VRM power phases than the B Just the premium B has more VRM phases than the X As overclocking depends upon VRMs, the chipset with more power phases will fill more over-clocking requirements.

3-PCIe Support

For the better performance of your system, the number of PCIe is noteworthy. PCIe 4 Support for B is limited as compared to X It means that X will provide you with faster and better PCIe support in comparison to B  X generally uses PCIe 4, while the use of PCIe 4 for B is limited. So, we can say that B is better than the B in this regard where no PCIe 4 port existed.

4-Price

The price of a product plays an essential part in picking up a preferable device. The best device is the one that provides you with more features and functionalities at an affordable price. You will not want to spend money on a product with fewer features and an expensive rate.

But if some products offer you more attractive features at high charges, you may consider that. While comparing the prices of B and X, we realized that B has a budget-friendly price compared to X The cost of the B is less than the X chipset.

One of the main reasons to launch B was that the X price is pretty high, and there was no chipset other than X in which PCIe Gen4 was available. There was no option for Mid-range customers to buy any AMD chipset in which they can enjoy PCIe Gen 4 as well. So, for affordability purposes, AMD launched B so that all customers can gain PCIe Gen4.

5-Chipset Fan

To keep the expenses down, the B chipset had some fewer features available in the costly X The considerable difference between these two chipsets is, X has a built-in Chipset cooling fan, while on other hand, B has no cooling fan on the chipset.

The cooling fan plays a notable role in keeping the temperature down and preventing it from heat up. The X chipset dissipates more power, due to which its temperature starts to increase that can cause damage to the system, so the built-in fan was made compulsory compared to the B chipset. So, a built-in cooling fan is essential for X chipsets.

6-Over-clocking Performance

Over-clocking is the ability of a device to run with better and boosted performance than its already specified speed. Most chipsets allow reset for fewer controls. But the chipset that allows higher performance is preferred to be the superior one.

If you have a low budget and want more over-clocking features in chipset than those already in the market, we will recommend B with AMD Ryzen 5 and Ryzen 7 Processors. If you have the Ryzen 9 Processor, you will need to go with X to avail of the maximum performance.

FAQ

Q# Does the B chipset contain PCIe ?

Yes, the chipset B has 20 PCIe 4 lanes for the general purpose of AMD Ryzen third generation.

Q# Do B have a chipset fan?

No, B does not need a fan heatsink as it does not heat up quickly as compared to X B has features that are preferable in AMD chips.

Q#What should you buy? B or X

Both of them are different. But X features more professional specifications as compared to B B offers high compatibility. But according to the price, B is less expensive with better features. You can buy B for unprofessional purposes.

Q#Why B less-expensive than X?

AMD launched B due to the costly rates of X For ease of people, a chipset with better features at a budget-friendly price was manufactured. So everyone could avail of faster PCIe Gen4.

B550 motherboard vs x570

Our Verdict: Both the B and X motherboards are suitable for any top-class gaming build. The B boards are more suitable for regular gaming builds that you can build with a reasonable budget. Whereas, the high-end builds that require extra storage for video editing are suited to X boards.

The release of the much-awaited B motherboards ended all the anticipation. These motherboards are the upgrade of motherboards with B chipsets.

That said, the range of B motherboards is quite diverse. You’ll find cheap budget-oriented options as well as boards with high-end features.

But the question is, are B motherboards better than X boards?

Don’t worry. This post is curated explicitly for answering this question. Here, I am going to simplify the differences between these two chipsets.

So, let’s waste no time and dive straight into the discussion.

Check out the comparison between mm and mm case fans.

xvs-bmotherboards

Is X better than B?

In technical terms, a motherboard with an X chipset is better than a motherboard with a B chipset. But in terms of reasonability, the B board is better.

You may ask:

Is X more future-proof?

No, the X motherboards aren’t future-proof. It is an end to the AM4 lineup, and the presence of more PCIe slots doesn’t make a difference to most users.

Also, Check out the battle-tested comparisons between Samsung SSD Pro and Samsung

Here are the five differences between the B and X motherboards:

1. Compatibility

The first thing to consider while comparing motherboards with different chipsets is whether they are compatible with your desired CPUs.

Not all motherboards support all types of CPUs. Depending on the chipset types, the compatibility differs across various models.

That said, the moboards with B chipsets come with good compatibility. These boards are compatible with Ryzen CPUs and beyond. Check out the comparison between NZXT Kraken Z63 & Noctua NH-D

That eventually means a B motherboard supports most CPUs under the Ryzen and Ryzen series. However, this B motherboard doesn’t support Gen 1 and Gen 2 CPUs from Ryzen.xvs-bmotherboards-comparison

Another thing you need to note down is that these B boards also don’t have APU’s that come under the Ryzen series.

Now, in the case of the boards with the X chipset, there isn’t any issue with the compatibility of APUs. Also, they are compatible with the Gen 2 CPUs, that is, the processors under the Ryzen series. But these boards are limited to Ryzen Gen 3 CPUs, unlike the B boards.

Therefore, if you look beyond Ryzen Gen 3 CPUs, then it’s B moboards you should go for. Other than this, you can settle with an X motherboard.

2. PCIe Support

The presence of the PCIe interface in your motherboard does make a difference. It results in facilitating the high-speed data transfer from GPU, SSDs, and other expansion cards.

In the moboard, the presence of PCIe means that your board can have a max bandwidth of 16 GT/s per lane instead of 8 GT/s that you can get from the PCIe interface.

It eventually means that you’ll get the advantage of using extra lanes for extra SSD slots.

Now, the PCIe support for the motherboards with B and X chipsets isn’t the same. Check out the comparison between NZXT Kraken Z63 & Corsair iCUE Hi Elite Capellix.

The most significant difference is that the B moboard connects the processor using the 4-lane PCIe connection, whereas the board with the X chipset uses PCIs And that is because the boards with PCIe have more lanes.

Eventually, it results in the addition of 16 PCIe x16 lanes to the X, but the B possesses none.

Though, for the B boards, PCIe connectivity will work on the CPU directly using the primary PCIe x16 and also the M.2 slots. That means B moboards can use PCIe for two devices, an upgrade from the B boards. Also, see our expert’s recommended fastest PCIe SSD.

Other than this, the X boards support dual PCIe M.2 slots. The B is also compatible with multiple ones, but only one of them would be supported by PCIe

3. Connectivity

Since there is a difference in the number of PCIe in the boards with B and X chipset, the difference in connectivity is also prevalent between them.

That said, the X board consists of 8 more USB ports than that of the B board.

Also, if you want motherboards that provide you a reasonable number of storage options, the board with the X chipset is a better option. As you will get additional 8 SATA ports on the X board, which can be reconfigured. Check out our expert’s recommended best RAM for Ryzen 9 x and Ryzen 9 x RAM.

4. VRM Power Phases

In the motherboard, the VRMs make sure that stable power is delivered to the CPU so that your processor remains in good health. The outcome here is the utilization of the maximum potential of the CPU.

That said, the more the number of VRMs, the better it is. The board will have better control over the power delivered and lessens the load on VRMs.

Now, between the X and B motherboards, the number of VRMs is higher on the X ones. And the main advantage here is that it allows the overclocking of powerful processors with stability.

Therefore, for squeezing out most of your system using a powerful processor, an X motherboard has the edge over the B

5. Price

Lastly, price plays a huge part when you consider the buying decision. The motherboards with X chipset are more premium options with extensive features compared to the B boards.

So, if you want to build your rig around a high-end processor like Ryzen 9, the X chipset is a perfect choice. Or else, for a cheap and mid-range option, the B motherboards are good to go with.

Here’s an explanatory guide on how to remove thermal paste from motherboard pcb.

Is X worth it over B?

If you ask whether X boards are better than B boards, I would say yes. But in terms of mass appeal, I would say no.

For any regular build, the features present in a moboard with a B chipset are more than enough. That said, a B board is almost like the X board aside from a few differences.

Now, an X board consists of various fancy features that won’t give any good advantage for any build. Unless you focus on building a high-end video editing system, it’s no use to use such a powerful board.

Final Thoughts

So that is the overall breakdown of the fundamental differences between motherboards with the B and X chipset. After reading this article, you’ll be able to find out the differences that exist between them.

Lastly, I hope that you would be able to choose the correct motherboard for your build. In case any confusion arises about anything, do let me know in the comments.

B550 vs X570 Motherboard - Gaming

B vs. BA

First off, BA, which has already been out and which we have covered, is not the same as B BA is made only for OEMs and SIs (system integrators) for pre-built systems. The entire point of BA was to basically get the number “” onto the box to make it seem new. BA is just B It’s identical. The only difference is that the name was changed for pre-built PC providers.

That out of the way, B is the actually new one that’s interesting. The AMD B chipset release date is June 16, with most manufacturer motherboards shipping by July. Outside of chipset choice, the biggest consideration would be VRM quality, PCIe generation usage, and BIOS quality, but that’s a different topic.

Future Support

selective support zen2

chipset processor support list

Outside of the I/O differences that we’ll discuss, the primary advantage for the series chipsets going forward is that AMD is segmenting its support for future CPU architectures. The B and X chipsets will both support the unreleased Zen 3 architecture when it launches, presumably later this year, while B and X will only support up to Zen 2 CPUs. In terms of product IDs, that means up to Ryzen will be supported on the series and series (most of the time), with some caveats, and at least up to Ryzen will be supported on the series. This additional future-looking support will be the driving reason for upcoming board purchases to consider series boards rather than series, especially considering a lot of the boards are otherwise almost certainly perfectly capable of driving stock or moderately overclocked CPUs of even the next generation. Officially, AMD only marked AM4 for support into , and it seems as if AM4 life has been expanded by at least another 6 months to a year with the series + Zen 3 support. Ryzen isn’t supported on all X and B boards due to limitations of space on the BIOS ROM. APUs are not supported on x or B, but desktop CPUs go through B

AMD B Chipset

amd b chipset block diagram

Here’s a block diagram of AMD’s B chipset. Remember that the CPU’s capabilities are independent and unchanged by the chipset outside of BIOS lock-downs, so PCIe Gen4 on the CPU will run directly to the primary PCIe x16 slot and primary M.2 socket. That means B motherboards, unlike their predecessors, will officially support PCIe Gen4 for up to two devices. Some early BIOS revisions on B motherboards also allowed this, but that was erased with later AGESA updates. The chipset downlink remains PCIe Gen3 x4 because the chipset doesn’t extend any PCIe Gen4 lanes to other devices, so the extra downlink bandwidth found on X is unnecessary.

Chipset Differences

Time to talk about the chipset differences. We made a table for this and have verified the information as accurate.

We’ll start with X vs. B chipset differences, as that’s likely the biggest question right now. Both chipsets support up to Zen 3 so far. We don’t know if they will support beyond that, but it seems unlikely. X uses a Gen4 chipset link, while B uses Gen3. That’s because X has PCIe Gen4 lanes off of the chipset that are separate from the CPU’s lanes, something B has 0 of. These are referred to as “general purpose” lanes and can be reconfigured into almost anything. Intel also has general purpose PCIe lanes on its chipset, but has additional phrasing for HSIO lanes, or high-speed I/O lanes, and makes distinctions between connected devices.

X’s Gen4 lanes can be split into sub-groups, and we’ll need to briefly cut to an AMD slide for that.

amd x pcie lanes

Here’s the AMD X lane configuration in more detail than AMD’s original block diagram. We’re interested in those large blocks on the right side. There are four sets of x4 lanes listed here, so that’s the 16 number we just saw in our table, and those can be broken into any of the configurations below them. For example, these could be broken into a single x8 PCIe Gen 4 slot, as illustrated by the orange bar on the left, and then the other 8 could be comprised of a PCIe Gen4 device and 4x SATA ports, or you could do 8x SATA ports, or if you’re making some weird mining board on X, you could do 8 PCIe x1 slots. You get the idea. It’s pick-and-choose up to 16, more or less, with only a few guidelines.

Back to our table, we’ll pick up on the Gen3 line. B has 10 PCIe Gen3, with only 2 reconfigurable to SATA. We should clarify that “reconfigurable” means this is something the motherboard manufacturer can choose to do, not something the user can choose to do.

Neither X nor B have Gen2 general purpose lanes, but both have 4x SATA III (6Gbps) ports natively supported, 0 SATA Express, and they split USB 10Gbps into 8 on X and 2 on B USB 5Gbps is 2 on B, with USB Mbps as 4 on X, 6 on B The total USB native support is 12 on X and 10 on B We listed it with speeds since the USB-IF totally screwed its naming convention, but if you prefer names, that’d be USB at Mbps, the originally-named USB at Gbps, and then whatever 10 is, because they keep changing the damn names and we can’t keep up anymore. It’s probably USB sqrt Gen Modern AMD CPUs also have 4x USB 10Gbps lanes, so you’ll always get at least that as long as the motherboard maker put the ports on the board.

Another reminder here: Limiting the chipset to this assortment of I/O devices doesn’t mean the motherboard is limited to just these. In addition to the devices powered by the lanes located on the CPU’s I/O die, which is the larger of the three chiplets on AMD’s design, the motherboard manufacturers can also buy third-party controllers to add more support. For example, a common choice is to buy an Aquantia NIC for 10Gb LAN. It’s not as common these days, but you sometimes see motherboard makers buying additional USB or SATA controllers to allow for more connected devices, or PEX/PLX chips to bifurcate the PCIe lanes. The chipset isn’t the only source of I/O, but it adds to cost to expand I/O capabilities, so most boards do stick close to the native support of the CPU and chipset combined. Similarly, boards also don’t have to use every single lane on the chipset if they don’t want to -- mini-ITX might be a good example of this, where a lot of them stop at 2 SATA ports.

B has been our go-to recommendation lately for anyone who isn’t making use of PCIe Gen4 and who doesn’t need the higher-end VRMs associated with X B and X are still perfectly capable and make sense for people who won’t use Gen4 devices. That said, going forward, the expanded support of X and B to include Zen 3 will likely change our recommendation toward B rather than B B supports up to Zen 2, uses a Gen3 link, and hosts zero PCIe 4 and PCIe 3 general purpose lanes of its own; instead, it runs 6 PCIe generation 2 general purpose lanes, compared to 8 on the X chipset. SATA III availability is 4 ports natively for X, 2 for B, with the option to split other lanes off into SATA. Those would come from your Gen2 general purpose lanes or from your SATA Express lanes, of which both last-gen chipsets have 2. Each SATA Express lane can become 2x SATA ports, or you can take both and turn them into a x4 NVMe Gen3 M.2 device.

SATA support on these is equivalent for USB 10Gbps, it’s 6 and 2 for USB Gbps, and it’s 6 and 6 for USB , or Mbps.

The primary difference between B and B is the increased PCIe general purpose lanes that also benefit from becoming PCIe Gen3, rather than PCIe Gen2.

Let’s recap first-gen Ryzen’s launch chipsets now: X, B, and A X is covered in our launch coverage, if you’re curious about that implementation.

All three of these stopped officially supporting Ryzen past the Zen+ CPUs. X, B, and A support includes the confusingly named Ryzen CPUs that have APUs in them, and often includes Ryzen desktop CPUs, but not always. That requires a beta BIOS. 

PCIe Gen2 general purpose lane assignment is 8 on X, 6 on B, and 4 on A, SATA III runs 4, 2, and 2, respectively, and SATA Express is identical on all 3. This is commonly split into M.2 or SATA devices. The USB 10Gbps support is 2, 2, and 1, from high-end to low-end, Gbps is 6, 2, and 2, and Mbps is , woe to you, oh earth and see, let him who hath understanding reckon the number of the beast.

That recaps the chipset differences in a clean fashion. There are a few other items to add:

dual gpu support

AMD is trying to position B as a cheaper version of X, rather than as a full step down in classification. The B boards technically didn’t support dual-GPU support, but B will, for whatever that’s worth. (It’s not much).

Based on AMD’s slide deck to media, the B chipset will not support the APUs, not to be confused with Zen 3 -- we have no idea if its APUs will be supported, assuming it has any. The Athlon G and Ryzen G and G APUs will not officially work in B
