PCIe 4.0 For All!
AMD has released, among other things, the specifications of their new B550 chipset designed for the latest third generation Ryzen processors. The chipset will offer 20 usable PCIe 4.0 lanes with a current generation Ryzen chip, along with up to four usable PCIe 3.0 and eight PCIe 2.0 lanes. It will natively support two USB 3.2 Gen 2 ports and a mix of up to a half dozen USB 3.1 and 2.0 ports.
While you are likely to be using some of those PCIe lanes for NVMe storage there is still room for up to eight SATA ports, after all there is little need for PCIe connected optical storage at the moment. The new chipset also means an update to AMD’s compatibility table as the B550 chipset is not quite as accommodating as the X570 which can support Ryzen 2 processors as well as current and upcoming generations. As you can see below the B550 will only support this current generation and at least one more future family. Take a peek to see your upgrade options, or head over to AMD for more info.
