AMD's B550 motherboards will bring PCIe 4.0 to the masses, but leave older Ryzen CPUs behind
When AMD’s excellent Ryzen 3000-series processors released last summer, snatching the desktop computing crown from Intel, one of their key features was support for the blazing-fast PCIe 4.0 interface—but only if you purchased a pricey X570 motherboard, too. No more. After months of constant leaks (and constant pining by enthusiasts) AMD confirmed Tuesday that it’s bringing PCIe 4.0 to the masses with the announcement of B550 motherboards, revealed alongside two extremely affordable new Ryzen 3-series processors.
