Do you know where there's any hard data on the actual speed of AMD's USB4 implementation in the 6xxx series? Everywhere I've looked, I get "USB4" then a blurb that USB4 can be "up to 40Gb/s" with the more honest stating that only 20Gb/s is actually required to meet the spec requirements.
What does AMD actually implement?
While we're on the topic, why is there basically no public information about Socket FP7 or it's chipset? Nothing on FP7r2 or FP8 either (by the way, upcoming 7xxx mobile chips support all three of these with likely different levels of motherboard capabilities). Why is there not much public for mobile AMD chipsets newer than a decade ago?
I haven't seen benchmarks, but my understanding is to officially claim USB4 support with Windows, 40Gbps and PCIe tunneling support are both required. This PC World article has some real world testing w/ a Ryzen 6000 laptop: https://www.pcworld.com/article/703578/usb4-support-amd-ryze...
I'm sure you can get a BSP contract w/ AMD to get implementation details (or simply have a relationship with a board design partner, but I'm not really sure why there would be an expectation for public information on something that's not really relevant to the general public).
