Part of AMD’s recent pre-announcement of its next generation Rome server processors, using 7nm chiplets and running up to 64 cores, is that the new processors will be compatible with current motherboards on the market. However, one of the new features of Rome is the use of PCIe 4.0. PCIe 4.0 has different standards for on-board signalling in order to get the required speed, so even though the processors are backwards compatible with PCIe 3.0, we expect new motherboards and new systems to be developed with PCIe 4.0 specifications in mind. Today, we saw the first early revision of such a motherboard.
