Both B550 and X570 are AMD chipsets. Some users want to know the differences between them and which one to choose. If you are one of them, you come to the right place. Now, continue to read this post from MiniTool tells you details about B550 vs X570.

B550 and X570

First, let’s see basic information about B550 and X570.


B550 chipset was released in June 2020. The B550 chipset is also designed to be paired with Zen 3 Ryzen 5000 series CPUs, but since this is also based on the AM4 socket, it supports Zen 2 (Ryzen 3000 CPUs and Ryzen 4000 series APUs). B550 chipsets are targeted at high-end gamers, content creators, and professional photo and video applications.


Introduced in July 2019, the X570 replaced the previous-generation X470 chipset and supported the then-upcoming Zen 3-based Ryzen 5000-series CPUs. It is the first chipset to support PCIe 4.0-based graphics cards and NVMe storage devices.

The X570 chipset is designed for AMD's AM4 socket CPUs. This means that if you own any previous generation Ryzen processors, you can keep using them. Note, however, that this only applies to Ryzen 2000-series CPUs, not 1st Gen Ryzen 1000-series CPUs.

B550 vs X570

Next, we will introduce information about B550 vs X570 from several aspects – chipset PCIe support, dual GPU support, USB and SATA connections, overlocking and performance and price.

B550 vs X570: Chipset PCIe Support

The main difference between the B550 and X570 chipsets is their PCIe lane versions.

AMD X570 motherboards have four lanes of PCIe Gen 4 from the CPU to the chipset, while AMD B550 motherboards have four lanes of PCIe Gen 3 from the CPU to the chipset. The X570 offers additional PCIe 4.0 lanes and it supports running two M.2 NVMe SSDs on PCIe 4.0, while AMD B550 only allows one M.2 NVMe SSD running on PCIe 4.0.

B550 vs X570: Dual GPU support

If you want to have dual graphics cards in your build, then your motherboard and CPU should support Nvidia's SLI or AMD's CrossFire. Both X570 and B550 chipsets support these features, but for B550 motherboards, only some premium and high-end options support them.

B550 vs X570: USB and SATA Connections

Besides PCIe lanes, other important connectivity options are USB and SATA. The X570 chipset supports up to 8 USB 10Gbps ports, while the B550 chipset supports only 2 of them. For USB 5Gpbs ports, the X570 chipset has none, while the B550 chipset has 2. Finally, the X570 chipset has only 4 USB 2.0 480Mbps ports, while the B550 chipset has 6.

B550 vs X570: Overclocking and Performance

Both X570 and B550 motherboards support CPU and RAM overclocking. However, VRM on the more expensive X570 tends to be a bit better compared to the B550 motherboard.

B550 vs X570: Price

The last important difference is the price of the motherboard. If you compare the prices of the B550 and X570 motherboards, the X570 is a bit more expensive than the B550 option.

Final Words

Now, you have known the differences between B550 vs X570. Besides, you can also know which one to choose. I hope this post can be useful to you.
