Motherboards have been improved a lot in a few years, and we can’t deny their importance in a gaming build. They connect the internal components of a computer together and make them work without any hitch.

The B550 and the X570 are the latest chipsets for AMD Ryzen processors, and both can overclock the Ryzen 5000-series processors. The B550 chipset is a budget-friendly chipset and replaces the B450 chipset, while the X570 chipset is considered premium and replaces the X470 motherboards.

Today we will compare both of these latest chipset motherboards and see which one provides a better value. These chipsets have significantly improved over the previous generation and provide many new features such as PCIe 4.0.

The X570 motherboards are slightly expensive but usually provide better performance and overclocking potential. 

On the other hand, the B550 chipset motherboards offer the best value for money. Many users get confused about whether to go with an X570 motherboard or a B550 one. After all, a PC can have only one motherboard.

So without further ado, let’s jump right into it.

B550 vs X570 Comparison

I will compare and analyze the best gaming motherboard feature by feature and break down everything for you. 

By the end of this article, you will be familiar with the features, strengths, and weaknesses of both of these chipsets. 

Chipset X570 B550
PCIe Lanes 36x PCIe 4.0 x16 20x PCIe 4.0 x16
PCIe Lanes Configuration 1x PCIe x16 or 2x PCIe x8 1x PCIe x16 or 2x PCIe x8
General Purpose PCIe Lanes to Chipset PCIe 4.0 PCIe 3.0
USB 3.2 Gen2 (10 Gbps) 8x 2x
USB 3.2 Gen1 (5 Gbps) 2x 1x
USB 2.0 4x 6x
SATA 12x 6x
Crossfire & SLI Yes Yes & No
CPU Support Ryzen 3000 & 5000 Ryzen 3000 & 5000

Both B550 and X570 chipsets support various form factors, although it is true that there are only a few X570 Micro-ATX motherboards. You can get your hands on an ATX motherboard if you want to use more expansion slots and ports to build a PC.

The Micro-ATX motherboards will be great for gamers who don’t want to spend much on the motherboard, as Micro-ATX motherboards are usually cheaper.

The Gigabyte X570 AORUS XTREME is a great X570 motherboard. Meanwhile, the Asus X570 ROG Strix X570-I Gaming is available in a compact design.

Similarly, you can find the B550 chipset in the ATX form factor, i.e., Asus ROG Strix B550-I Gaming, and Micro-ATX form factor like Gigabyte B550M AORUS Pro-P.

These are just a few choices; the market is filled with different form factor motherboards. With lots of options, if you want a Micro-ATX PC system, then B550 should be the chipset of your choice.

Backward Compatibility

AMD Backward Compatibility

Backward compatibility in motherboards means that a motherboard can work with older processors too. The B550 offers 100% compatibility with AMD Ryzen 3000 and 5000 CPUs.

Similarly, the X570 chipset motherboard can support Ryzen 3000 and 5000-series processors. You don’t necessarily need to upgrade if you are using a 3000-series CPU with an X570 chipset motherboard.

This is something you should keep in mind before buying a motherboard. An X570 or B550 motherboard would work just fine with a relatively newer CPU, but you can’t run older processors on these motherboards.

Some of the variants of these motherboards do support Ryzen 2000-series processors.

PCIe 4.0 Lanes

Many consider this factor to be the most significant difference between X570 and B550 and what practically sets X570 apart from B550.

Both of these chipsets come with PCIe 4.0 support. But B550 connects to the processor through PCIe 3.0 lane, and the X570 connects to the CPU through the PCIe 4.0 lane.

The PCIe 3.0 transfers data at 8 GT/s, while the PCIe 4.0 has a 16 GT/s transfer rate. Hence PCIe 4.0 is twice as fast as PCIe 3.0. 

The real-time performance difference between PCIe 3.0 and 4.0 is not much, as current-generation devices cannot fully saturate the PCIe 3.0.

PCIe 4.0 GPU Slots

Various B550 and X570 chipset motherboards in the market come with PCIe 4.0 supported GPU slots. Now both these chipsets support the same version of the GPU slot.

The higher the number of lanes, the higher the data transfer speed. For example, a PCIe x16 slot would be faster than a PCIe x8 slot, and a PCIe x8 slot would be faster than a PCIe x1 or x4 slot.

The B550 and X570 chipset motherboards offer X16 PCIe 4.0 slots for GPU. However, the B550 chipset generally provides only one PCIe x16 slot, whereas most X570 motherboards come equipped with multiple PCIe x16 slots.

That is why X570 is ideal for professionals, content creators, enthusiasts, etc.

PCIe 4.0 M.2 Slots

PCIe 4.0 M.2 Slots

PCIe M.2 slots allow NVMe SSDs to connect to the motherboard through the PCIe interface. Both the B550 and X570 come equipped with PCIe 4.0 M.2 slots. But B550 usually has one or a maximum of two M.2 slots.

In comparison, X570 motherboards can even have four M.2 slots. In addition, the benchmarking results have shown that Gen 4 M.2 slots boost the performance considerably, so having more of them is a huge advantage.

This is another reason overclocking enthusiasts, video editors, and streamers go for X570 Chipset. There is a higher number of USB 3.2 Gen2 Ports in X570 motherboards.

The B550 chipset provides two USB 3.2 Gen2 ports. The X570 chipset, on the other hand, supports eight USB 3.2 Gen 2 ports.

Each USB 3.2 Gen2 port can transfer data at the rate of 10 Gbps, so more Gen 2 ports mean faster data transfer, leading to faster processing and better performance overall.

LAN Support

The X570 chipset offers the latest LAN and Wi-Fi solutions to provide lightning-fast data transfer.

The X570 chipset can come with 5G and even 10G LAN support and the latest integrated Wi-Fi technology to provide a smooth online experience with less latency.

In contrast, the B550 motherboards usually have 1G or 2.5 G LAN, which is enough for most people to boost the network speed by a notch. Still, the X570 takes the lead in this category too.

Future Proof

Based on the technical aspect and latest PCIe 4.0 support, it can be said that the X570 is more future-proof. But both B550 and X570 have the same lifespan, especially regarding future CPU compatibility.

Both of these chipsets only support up to Ryzen 5000-series CPUs. Neither B550 nor X570 will support the next-generation Zen 4 Ryzen CPUs.


The B550, as well as X570, can overclock RAM and CPU. But here is the deal; the more powerful the VRM, the better the overclocking potential of a motherboard.

The high-end X570 motherboards generally have better VRM, providing better overclocking performance.

Regarding mid-range motherboards, high-quality B550 motherboards provide better performance than budget X570 motherboards.

There are some great-value B550 motherboards in the market that have stronger VRMs than budget X570 motherboards.

For example, B550 Tomahawk has better VRMs than similarly priced X570 motherboards, i.e., MSI X570 Gaming Edge Wi-Fi.

It is safe to say that X570 takes the trophy for the high-end overclocking build, whereas B550 is an excellent option for mid-range overclocking.

Price Comparison

The X570 is generally more expensive than B550, especially regarding high-end motherboards. The B550 chipset was released to make PCIe 4.0 support more accessible to consumers since they were unhappy about spending so much money on the X570 motherboard.

The price of various Premium B550 motherboards is similar to budget X570 motherboards. That is why many users prefer a B550 motherboard, as it offers compatibility for newer CPUs with PCIe 4.0 support at an affordable price tag.

Both chipsets are compatible with Ryzen 5000-series CPUs. They can support and unleash stable performance out of AMD 5000-series CPUs to support AAA titles and even professional video editing or streaming.

But the X570 provides the additional PCIe 4.0 support and advanced connectivity, giving the advantage to competitive gamers and professionals who often carry out complex tasks. Still, most users would be satisfied with a B550 motherboard. 


In short, X570 is indeed better than B550 when it comes to fancy features and advanced specs. Competitive gamers that simultaneously stream can also go for X570 if they have money.

However, will most average users necessarily require those fancy features? No. Most users will be content with the features and performance of a B550 motherboard. Most importantly, it is economical and offers excellent value for money.

If you are a professional content creator or video editor building a PC system with multiple premium storage, then the PCIe 4.0 M.2 slots of X570 will genuinely benefit you.

So the ideal chipset for you is the one that suits your needs and budget. Go for the B550 chipset motherboard if you enjoy decent gaming and have a limited budget.

Buy an X570 motherboard if you have the budget for it, and you can take advantage of the upgraded PCIe Gen 4 support.
