AMD Ryzen

AMD has added support for the Ryzen 5000 series processors with a new B2 stepping. The new B2 stepping should allow AMD to improve the supply of processors which have been in short supply lately.

AMD suggested the B2 stepping should be available in a few months as the next batch of processors is diffused. The new stepping is not intended to bring new features but rather its more of a refinement of the manufacturing.

Historically many microprocessors and video cards have seen multiple steppings. Stepping are simply refinement of manufacturing. The goal is primarily to improve the yields.

The AMD Ryzen processor have been very successful in the market. The Ryzen 3000 introduced PCIe 4.0 support which led to improved SSD performance. The X570 with the Samsung 980 PRO can boot windows in 20 seconds or so.

Availability of Ryzen 5000 processors has been OK but prices have bounced around somewhat. AMD is manufacturing more processors to meet demand. CPU supplies are not nearly as bad off as video cards.

The new B2 stepping will work on any motherboard that supports Ryzen 5000 processors. AMD B450 and X470, B550 and X570 are all suitable. A BIOS update may be needed for B450 or X470. The X570 is the best choice for Ryzen 5000 processors with full PCIe 4.0 support.
