The wait is almost over for AMD’s more affordable X570 counterpart. Guru 3D has gotten word of the B550 chipset’s supposed specifications, which it says is reminiscent of the X470 platform.
As expected, the biggest difference is the lack of PCIe 4.0. Other differences include two USB 3.2 Gen 2 ports (instead of 8), six USB 2.0 ports (instead of 4), and 4+4 SATA3 (instead of 4+8).
So compared to the top-end X570, it offers fewer USB 3.2 Gen2 (10 Gb/s) ports, does not support PCI Express 4.0, and communicates with the Ryzen processor via four PCI-E 3.0 lines (instead of PCI-E 4.0), which limits the total bandwidth controllers built into it. That said, that’s pretty much it though. Well, that and likely pricing.
