It’s a glance at the B550 Chipset’s features and characteristics.

x570 vs b550: AMD’s X570 is the top-of-the-line chipset, while the B550 is the runner-up. Both of these chipsets support 5000 Series AMD CPUs. The X470 and B450 chipsets that before were superseded by these newer ones. These two AMD motherboards, X570 and B550, feature PCIe4.0 (for both GPU and NVMe Storage), making them the best AMD motherboards currently available. This article will compare the x570 vs b550 chipsets, as well as provide a mini-buying guide that tries to answer the key question: “Is it better to buy the X570 or the B550?” Is it better to buy an X570 or a B550 motherboard?

Chipset B550

After the X570, the B550 Chipset was released in June of 2020. It replaces the previous generation B450 Chipset and costs significantly less than the X570 Chipset. Although the B550 chipset is geared at pairing with the Zen 3 Ryzen 5000 Series CPUs, the AM4 socket of this motherboard also supports Zen 2 processors (Ryzen 3000 CPUs and Ryzen 4000 Series APUs). Above all things has been mentioned about x570 vs b550.

It’s a glance at the B550 Chipset’s features and characteristics.

The B550 Chipset does not contain PCIe 4.0 lanes since the communication between the CPU, and the B550 Chipset is via PCIe 3.0 x4 lanes. It is possible to develop motherboards for B550 CPUs that provide direct PCIe lanes for graphics cards and NVMe storage. Above all things has been mentioned about x570 vs b550.

Even motherboards based on the B550 Chipset are aimed at professional photographers, video editors, and high-end gamers and content creators. Aside from the Chipset’s PCIe 4.0 lanes, the B550 features everything of the X570’s bells and whistles.

The B550 is primarily designed for use with Ryzen 5000 Series CPUs based on the Zen 3 architecture in terms of CPU compatibility. The Ryzen 3000 Series CPUs, on the other hand, can be put to use. The B550 Chipset’s maximum power draw is approximately 6W. The B550 Motherboards do not feature any chipset cooling fans, unlike the X570 Motherboards. Above all things has been mentioned about x570 vs b550.

The X570 chipset/motherboard

The X570 Chipset will be the starting point for our B550 versus X570 analysis. A whole new chipset was released in July of this year, including compatibility for the Ryzen 5000 Series CPUs, which were still in development at the time. It is the first chipset to enable graphics cards based on PCIe 4.0 and storage devices based on NVMe. Above all things has been mentioned about x570 vs b550.

For gamers, professional photographers, and videographers, the X570 chipset is a must-have component. The X570 Chipset supports AM4 socket CPUs. It means that if you already have a Ryzen processor from the previous generation, you can continue to use it. Only Ryzen 2000 Series CPUs are eligible for this feature; it does not apply to 1st generation Ryzen 1000 Series CPUs.

The X570 Chipset consumes between 11W and 15W of electricity depending on PCIe 4.0 lanes. The previous X470 Chipset generation had a maximum power drain of 6W, a huge increase. Since the X570 has a dedicated cooling fan, most X570 motherboards provide this feature. Above all things has been mentioned about x570 vs b550.

The B550 and X570 processors are being compared.

AMD’s B550 and X570 Chipsets have been known only for their respective specifications up to this point. Here is a quick comparison of the B550 and X570 chipsets. Above all things has been mentioned about x570 vs b550.

Chipset differences between the B550 and X570.

The B550 and X570 chipsets are very different in terms of PCIe lanes. The X570 Chipset uses PCIe 4.0 lanes to connect to the CPU, while The B550 Chipset uses PCIe 3.0 lanes.

PCIe lane upgrades from the X570 Chipset are PCIe 4.0, while upgrades from the B550 Chipset are PCIe 3.0 only. Because the GPU is connected directly to the CPU through PCIe 4.0 on both the X570 and B550 motherboards, you can choose the X570 motherboard if you require additional PCIe 4.0 connectivity from the chipset. B550 motherboard would suffice in this case. Above all things has been mentioned about x570 vs b550.

Performance and Overclocking

Overclocking the CPU and RAM is possible on both the X570 and B550 boards. Even so, the VRM performance of the X570 is slightly greater than that of the B550 motherboards.

The X570’s PCIe lanes are entirely PCIe 4.0, resulting in a maximum power draw of 15W. As a result, nearly all X570 motherboards have a cooling fan attached to the chipset. B550 Motherboards don’t have this problem. Above all things has been mentioned about x570 vs b550.

Dual Graphics Card Compatibility

Nvidia’s SLI or AMD’s CrossFire compatibility is required for dual-graphics card configurations in your project. These functions are supported by both X570 and B550 chipsets, but only a few high-end and premium B550 motherboards support them.

USB and SATA ports are available for data transfer.

USB and SATA are key alternatives to PCIe lanes. USB 10Gbps ports are supported by the X570 Chipset, while the B550 Chipset supports just two. The X570 chipset does not have any USB 5Gpbs ports, but the B550 chipset has two. Finally, the X570 Chipset only offers four USB 2.0 480Mbps connections, but the B550 Chipset has six.

The X570 and B550 chipsets both contain four dedicated SATA III 6Gbps ports; however, the X570 chipset has an additional eight ports and the B550 chipset has an additional two ports. Above all things has been mentioned about x570 vs b550.


The cost of motherboards is the final and most significant distinction. X570 motherboards are a little more expensive than B550 alternatives in terms of price. X570 Chipset’s PCIe 4.0 lanes demand a costlier PCB, better VRM, and a cooling solution for X570.

Assured for the Future

AMD’s future Ryzen 6000 Series CPUs will use an AM5 socket instead of the long-serving AM4 socket. As a result, motherboards like the B550 and X570 are no longer considered future-ready.

X570 or B550: Which is Better for Gaming?

 When comparing the B550 and X570 Chipsets, it’s evident that the PCI-e connectivity of these two alternatives is the deciding factor. X570’s PCIe lanes are all PCIe 4.0, whereas B550’s PCIe lanes are only PCIe 3.0.

Nevertheless, PCIe 4.0 is available on both chipsets for graphics cards and M.2 NVMe drives connected directly to the CPU. Because both the B550 and the X570 include PCIe 4.0 GPUs and at least one NVMe storage, the cost is an essential consideration when choosing between the two. In the absence of a requirement for additional PCIe 4.0 lanes, a B550 Motherboard with robust VRMs, overclocking capabilities, and a plethora of other connections is the ideal option. Above all things has been mentioned about x570 vs b550.

The X570, on the other hand, is the ideal choice if PCIe 4.0 is a top priority for you. The VRMs for high-end Ryzen 7 and Ryzen 9 CPUs are also better for continuous overclocking.

 The B550 vs X570 Chipset Comparison

 Choosing between the B550 and X570 models is a matter of comparing specific models for their prices, features, quality, etc., due to the price overlap between the two models. Based on prior chipset generations, many buyers will conclude that X570 is superior to B550 because there was an obvious distinction between the budget and high-end chipsets (B450 and X570, for instance). Above all things has been mentioned about x570 vs b550.

 For the most part, the X570 is a better chipset, and it has more overall capabilities, connectivity and flexibility than the B550 does. However, this does not indicate that you should get an X570 instead of a B550, as “high-end” B550 boards might be just as good (if not better) than a competing X570. Moreover, a solid B550 can do everything you need; X570 boards aren’t likely to advantage most users. You may be interested to learn that there are several distinct technological variations between the B550 and X570 chipsets, which are as follows:

Except for the Gigabyte B550 Aorus Master (which has two PCIe 3.0 x4 M.2 slots), all B550 motherboards allow multiple M.2 SSDs, but only one of those slots can be PCIe 4.0 compatible (with only one exception; the Gigabyte B550 Aorus Master does offer dual PCIe 4.0 x4 M.2 slots). This capability is useless for the vast majority of X570 motherboards, as the likelihood of purchasing a single PCIe Gen4 SSD is extremely minimal these days because of the high cost (let alone buying 2). Above all things has been mentioned about x570 vs b550.

It is important to note that both the X570 and the B550 have a primary PCIe x16 slot (full length for graphics cards) that supports PCIe 4.0 on both models. B550 boards will have PCIe 3.0 slots for secondary PCIe cards, whereas X570 boards may have PCIe 4.0 for those secondary PCIe slots, depending on the model (depending on the model). PCIe Gen4 isn’t much of a deal because few people use the extra slots and even fewer devices that benefit from PCIe Gen4. Above all things has been mentioned about x570 vs b550.

Extra Lanes for the Newer PCIe 4.0: X570 has additional PCIe 4.0 lanes (connections) available on the CPU and also uses PCIe 4.0 lanes to connect the CPU and the chipset, which should not be confused with the PCIe slots for connecting SSDs, GPUs, and other cards (on B550 this chipset link uses PCIe 3.0 lanes). Above all things has been mentioned about x570 vs b550.

It means that the X570 offers faster and more versatile I/O with several connected devices. A 3rd-generation Ryzen 3000 CPU gives you 24 PCIe 4.0 lanes on the CPU, and with an X570, all 24 can be used (16 for GPU, 4 for storage, and 4 for chipset link), while a B550 gives you 20. If you’re more advanced and wondering how many more lanes an X570 gives you, for example, in the case of building an SLI/NVLink PC where lanes can be important, a 3rd-generation Ryzen (16 for GPU, 4 for storage). Above all things has been mentioned about x570 vs b550.

In contrast to B550 motherboards, some X570 motherboards provide 5G and 10G LAN ports, significantly faster than the 1G or 2.5G LAN ports found on X570 motherboards. Most users don’t have an issue because 1G LAN provides enough speed (gaming included).

The X570 supports Ryzen 3000 Series APUs: The latest AMD APUs cannot be used with B550 motherboards (Ryzen 3 3200G and Ryzen 5 3400G). Many people won’t care about this because the possibilities of using a high-end X570 platform in conjunction with a low-cost APU are small.

When it comes to Ryzen 2000 CPUs, only the X570 supports them, while the B550 does not. The 2700X is the last Ryzen processor to support the 2000 series. The vast majority of people using an X570 with a new Ryzen 3000 or 5000 processor will not care about this.

Small chipset fan: X570 motherboards contain a small built-in chipset fan to help keep the board cool, but B550 motherboards do not have a chipset fan, as they consume less power and generate less heat. We’ll get into the specifics of what this implies in a moment.

More USB 3.2 Gen 2 and SATA 3.2 Gen 2 ports are supported by the X570: X570 provides more ports to connect additional devices, depending on the individual model in question. Most of these differences between B550 and X570 won’t matter to most people, but it’s worth noting for specific use scenarios.

Why Are There Fans on X570 Motherboards?

With more PCIe lanes (from both processor and chipset), the chipset consumes more power (and generates more heat) than the B550 chipset, which only has PCIe lanes via the processor. Gigabyte’s X570 Aorus Extreme motherboard is the only one of the X570 motherboards that don’t feature a small built-in fan, called a chipset fan.

In the past few years, motherboards have been without chipset fans, and some enthusiasts aren’t happy with their reintroduction on the X570. Fans with a smaller diameter produce a higher-pitched, “whinier” sound than larger fans because they have to work more to push the same air volume.

The X570 chipset fan generally stays idle, only firing up when PCB (the physical board) temperatures hit a particular level, according to the common consensus among X570 users; however, the noise isn’t apparent over other fans in the system (such as when running multiple super-fast PCIe 4.0 devices, when overclocking, etc.). I wouldn’t worry about the noise unless you’re extremely concerned about designing a completely silent system.

 On the other hand, a chipset fan adds a possible point of failure to your system and replacing it can be a hassle. Because they are proprietary fans, you can’t usually replace small chipset fans when they fail. I wouldn’t consider the chipset fan when deciding between the X570 and the B550 unless you care about these two factors. However, it’s worth noting for the sake of completeness.

Which is better, X570 or B550, in terms of overclocking?

 Overclocking a mid-to-high-end CPU or just running a high-end Ryzen 9 3900X or 3950X at stock speeds necessitates consideration of VRMs in addition to the chipset fan. Are the VRMS on X570 motherboards superior to those on B550? Check out our FAQ for more information on what VRMs are, but they are the section of a motherboard that is in charge of keeping things cool. Overclocking and running high-end CPUs are made possible via a board’s VRM. Since high-end X570 boards have the best VRMs of any AMD board, it makes sense that the enthusiast chipset (X570) would have better VRMs than B550.

 It gets even better: I’m not talking about the ultra-premium, extremely costly boards that are not worth it for the vast majority, and in the mid-range board competition between premium B550 boards and budget X570 models, the former has the stronger VRMs overall.

Benchmark king Steve from HardwareUnboxed did a general B550 vs X570 VRM test, and I can recommend his videos as a good, reliable source, but the gist is that you can get a sub $200 (US) B550 like the B550 Tomahawk or B550 Aorus Pro that has better VRMs than similar-priced X570 boards like the X570 Pro4 or X570 Gaming Edge WiFi. To be sure, I find it puzzling because X570 is intended to be the enthusiast-grade chipset, but B550 is the more recent model (X570 has been available for some time), so the beefed-up VRMs make sense.

There are many low-cost B550 motherboards with superior VRMs than low-cost X570 motherboards, to name just a few. Because of this, it is difficult to recommend an entry-level X570 over a top B550 because the latter provides superior cooling for the money, with an X570 in this price range only making sense if you need the X570 chipset’s features (explained earlier).

Is the X570 More Resilient Than the B550 in the Face of Uncertainty?

Even though it’s possible to say yes, it’s best to say no. Allow me to elaborate. Both chipsets, B550 and X570, are anticipated to only support up to Zen 3 (Ryzen 5000) in terms of CPU compatibility, and any CPUs beyond that will likely require a new motherboard (and new CPU socket, i.e. AM5).

When it comes to “future proof” PCIe 4.0 support, the X570’s advantage over the B550 is that it has more PCIe Gen4 slots (supports multiple PCIe Gen4 devices) and more PCIe Gen4 lanes. However, as previously said, this isn’t a significant consideration for most consumers.

Is the X570 a Better Buy Than the B550? (Pros of Each)

Let’s look at why you should choose either the X570 or the B550. With the introduction of the B550, AMD’s high-end chipset for enthusiasts and power users seeking the greatest functionality, the B450 has been replaced by the B550.

Is the X570 better than the B550? Yes, in theory. Is it that important to most people? Many B550 motherboards have enough quality and features for a conventional PC build, even with high-end components.

A direct replacement for B450, the B550 is more like a watered-down version of its sibling X570. The extra features and capabilities of the X570 platform aren’t likely to be utilised now or in the future.

However, unless you’re putting together a high-end video editing PC and investing heavily in storage, it’s unlikely that running numerous PCIe Gen4 M.2 SSDs on an X570 will be worth the expense.

I used an MSI X570 Gaming Edge WiFi in a recent build for someone’s setup.

On top of all that, the VRMs of the B550, like the X570, are on par with or even better than those of the B550 (when comparing price). There are more inexpensive B550 versions to choose from and more options for mITX or USB-C-enabled devices than there are for the similarly priced X570 boards. It doesn’t matter which B550 or X570 you choose if you want to build a strong AMD Ryzen 7 or 9 system, so it all comes down to your budget and evaluating the various available models.

Advantages of the B550

Some models are better deals than the X570 at the same price (depends on your needs)

Others provide superior VRMs for the same or less money.

With a lower price, some offer superior networking capabilities

Because X570 does not have many Micro ATX variants, it is the only genuine option for those who need a smaller mATX motherboard.

A cheaper option for cases like the NZXT H510 with a front USB Type-C connector to acquire an internal front USB Type-C header (X570 boards with USB-C front headers cost more). Because there is no chipset fan on the board, there is no chance of any board noise and no need to replace the fan in the future.

Advantages of the X570

Several versions are better deals than a comparable-priced B550 in terms of value (depends on your needs)

  • Multiple PCIe 4.0 M.2 SSDs can be supported.
  • It is possible to provide more than one PCIe 4.0 expansion slot
  • There are more USB 3.2 Gen 2 ports on most devices.
  • The only true choice for 8 or more SATA connections
  • Faster total connectivity with more PCIe 4.0 lanes
  • Multi-GPU support at its finest (AKA NVidia SLI)
  • Ryzen 3000 APUs are supported (3200G and 3400G)
  • Ryzen 2000 CPUs are supported (Ryzen 7 2700X, etc.)
  • The only option to obtain ultra-high-speed LAN connections of 5G or 10G

Extensive overclocking at its finest (remember always to use the extra 4 pin CPU connector as well as the main 8 pins)
