    USB4 is TB3 “compliant” isn’t it?
    I was recently playing around with USB4 on some AMD NUCs, trying to get thunderbolt networking to work in a mesh (3 nodes, ports each, interconnected so each had a route to the other 2).

    Ultimately, the premise wouldn’t have worked for what I was trying to achieve.

    Regardless, I found it flakey when I was labbing it.
    I found it depended on which USB was connected to the other, would often fail to initialize correctly, sometimes just turning a cable around would fix it (I know not all cables are made the same, certainly a big factor).
    I’ve read quite a few write-ups of “it just working” on intel nucs.
    And I’ve (now) read a lot of write-ups on AMD thunderbolt being “compliant”, but not really 1st party like intel TB is.

    Unfortunately, I think if TB connectivity is important to you, intel is still the way to go.
    Similar with CUDA and NVidia.
