    Has anyone had any luck getting the 6800 running in Clear Linux? I spent a few days on it last month and couldn't get it working.

    Not just with that. Marek's last two biggie optimization patchsets are not even merged yet. ACO would just be the icing on the cake.

    Michael Marek has merged the first MR from the above two links already. Mesa 21.1 will be VERY fast.
    I wonder how big the delta is between the 6800XT and the 3080 now.

    There's also a new optimization MR for glthread: https://gitlab.freedesktop.org/mesa/..._requests/9029

    Looking good for AMD.

    Nvidia and Intel should team up and get their st together because the last 2 years at least in favor of AMD ATI, they are way way ahead of intel since Ryzen and intel doesn't even look like to have a plan to get back on them. I would never imagine a future like this well but Intel is gonna be the new shorting stock instead of GME!

    Sure. No point - just trying to understand why we see such massive swings from AMD much worse to much better to Nvidia.
    it was the time of the first Nvidia RTX release i read some articles about computer science history it was about how to make the hardware faster for the same algorithm compared to the speed up in finding new algorithms who are smarter and run faster on the old hardware. means software improvement instead of hardware improvement.
    in this article where many examples and the hardware improvement for the same algorithms was like 5-10 times faster over 30 years....
    in the same time new algorithms for the same technical problem speeded up by factor of 80 and more.
    this was about raytracing in mind the point is Nvidia did build hardware implementation for raytracing menas the same algorithm but better hardware for it. and AMD does not have full hardware logic for the complete old algorithm instead it is only hardware assisted means software with some hardware assistance.

    now you maybe think the amd solution is slower yes if you use the old same algorithms like nvidia do.
    but imagine the point: what if AMD found new algorithms who nvidia did not have hardware for.

    remember what i said first in the same time 30 years of computer history hardware speed up was 5-10 times but compared to this smarter algorithms speed up *80 or more.

    this means there is a posibility that amd can outsmart Nvidia by the use of new algorithms in the game engines

    Hey I'm famous! :-D Kinda makes sense that someone who is that interested in drivers would hang out here, doesn't it? :-D

    I think you meant to say ACO back-end here.

    early nvidia games who use RTX instead of microsoft DXR for sure do not run on AMD hardware. not in my knowelege.
    all the games who run on AMD hardware are DXR games or Vulkan games.

    whats your point? don't you think a game engine utilize DXR or Vulkan in a different way ?
    if all game engines would do it in the same way then why there are differences in the performance?...
