AMD's 600-Series Chipsets Pass PCIe 4.0 Validation

AMD’s 600-Series Chipsets Pass PCIe 4.0 Validation

Posted on

When AMD teased its upcoming Ryzen 7000 (Raphael) processors for the AM5 socket, the chipmaker indicated that the Zen 4 chips support DDR5 and PCIe 5.0 interfaces. However, AMD did not say whether PCIe 5.0 will be supported only by the upcoming CPUs or by both processors and AMD’s 600-series chipsets. So, for now, it looks like PCIe Gen5 is reserved only for CPUs.

This week it transpired that PCI-SIG had validated the interoperability of AMD’s 600-series AM5 chipsets with PCIe 4.0 x4 devices at a 16 GT/s data transfer rate, which may indicate that the company’s next-generation core logic does not support PCIe 5.0. Considering that ASMedia designs AMD-branded chipsets, it will not be shocking that the development is somewhat out of sync with AMD processors since the two companies use different interface IPs.
