This can be observed in one of the block diagrams that was leaked for red team’s AM5 chipset and socket. There is no indication of PCIe 5.0 anywhere in the diagram, but it does suggest that 600 Series motherboards will offer additional PCIe 4.0 lanes over current models.



What’s interesting is that Intel’s upcoming 12th Gen Core processors, Alder Lake, will feature support for PCI Express 5.0 to some extent. This has been confirmed in slides that were shared earlier this week during the company’s Architecture Day 2021 event.
