USB4

[testcy]

I am looking at AMD's website and under connectivity I see USB 4 (40Gbps) listed for Ryzen 5 8600G, but not for 7600X and 9600X.

Am I missing something?

The Ryzen 7000/9000 CPUs have it provided (on X870/X870E) via a third party chip that usually eats 4 PCI-E lanes from the CPU.

 

I would assume that the Ryzen 8000 series CPUs don't need the third party chip, since e.g. a board like Gigabyte's B650E Aorus Elite ICE says it can do 40 Gbps through a USB-C port with a 8000 CPU.

But 8600G only supports PCIe 4.0, while 7600X and 9600X both support PCIe 5.0?

The APUs are usually laptop derived. What makes sense for a laptop doesn't necessarily translate to a desktop. E.g. supporting USB4 and not PCIE 5.0 might seem illogical, but for a laptop,.. not so much.
