Yesterday we talked about HP pre-built systems featuring the AMD B550 chipset now it appears actual specifications on AMD’s B550 chipset have surfaced. We know that B550 will be pretty cut-down from the feature-set that you get with AMD’s X570 chipset. With that B550 will completely lack PCI-Express 4.0 support.
B550 will also only support 2x USB 3.2 Gen2 devices, 6x USB 2.0, 4 + 4 SATA3 connections. Also the interlink between the chipset and CPU is done via a 4x PCI-Express 3.0 interface, which will mean there is less bandwidth for communication between the CPU and chipset compared to X570. While this was never an issue in the past with AMD’s Ryzen products, it is worth noting. B550 chipset-powered motherboards and other products are expected to launch in October.
