    Well, i put a notice and pictures when everybody could spot these scale up scale down drivers tendencies.

    I think that my point is more than regular one and not irrelevant at all. This to me is so obvious amdgpu goes down with more cores, while nvidia scales up - here are more pictures, this is very easely noticable in majority GL benches Micheal posted in this article



    My comment is about amdgpu driver POV only really, i don't care which hardware combo is better and so on, since quality of drivers mostly makes things better or worse... Maybe i should just say hi bridgman bump mareko to see these

      This could become a trademark thing with NIVEA, Hamburg, Germany. --- Apart, that it looks like...

        If you don't enabled it?

        @Michael:

        I'm running here _all_ the time with

        mesa_glthread=true
        radeonsi_assume_no_z_fights=true
        radeonsi_commutative_blend_add=true
        R600_DEBUG=sisched

        in /etc/environment

        R600_DEBUG=sisched show big boost with UH, UV (US)

        And don't forget to set this for _GL_ (only):

        cpupower frequency-set -g performance

        With _Vulkan_ it show ~10% decrease on my devel/testing system.

        Greetings,
        Dieter

          Dude.. The AMDGPU drivers do not "go down" with more cores. They just go up on the i3's cores that are clocked higher and have more IPC (Instructions Per Clock). Multiple people have said this already. Everyone agrees with you that Nvidia's drivers take better advantage of higher-core CPUs. No one is disputing that.

            Well, it goes down I am talking about this specific tendency. Michael benches in this article show exactly that this happen, especially when you look at nvidia results.

            amdgpu obviosly scale down with more cores in these examples, while nvidia driver scale up.

            They just go up on the i3's cores that are clocked higher and have more IPC (Instructions Per Clock).
            I know what is IPC, but that does not matter here . As nvidia driver scale up fine with both these Intel and AMD CPUs, while amdgpu scales down going from these 2 cores to 4 - i mean that is so obvious

            Multiple people have said this already.
            I know that but i don't care, as this does not matter in this case

            Everyone agrees with you that Nvidia's drivers take better advantage of higher-core CPUs. No one is disputing that.
            I don't care about that also and i am not trying to disputing anything, i don't care that nvidia driver is better there... i just comment that amdgpu is worse as it does not scale there which is worse for an user who will switch to these more core CPUs potentionaly, and got expected Horse Shit like this bench showed, etc... probably some people here does not clearly understand my point, but well what I can do about that

            Again i don't care that nVidia is better and i don't care about CPUs... i have in my mind average Joe who ask: Should these 4 core CPUs improve my gaming performance, i currently have 2 core? And answer is - yes, if you are using nvidia driver, with amdgpu no - there it will go mostly down

              Oh good grief. The amdgpu+mesa stack does *not* "scale down with more cores". If you run on the same CPU (eg Ryzen 1200 or whatever) with 2 cores enabled vs 4 cores enabled you will get the same or higher performance with 4 cores.

              If you want to prove that amdgpu+mesa goes down with more cores you need a graph that shows Ryzen with 2 cores enabled vs same Ryzen with 4 cores enabled, not two different CPUs with two different core designs. I don't believe that graph exists. Please do not create one with a paint tool.

              The amdgpu+mesa stack as tested (not sure if "as-tested" enabled threading) can not take much advantage of the Ryzen's additional cores, and so the Pentium's higher clocks end up having more impact on frame rate than the additional cores.

              With the NVidia driver the gain from additional cores outweighs the loss from lower clock speeds.

                Yes, theoretically and as expected i agree In practice something else happen here it seems.

                If you want to prove that amdgpu+mesa goes down with more cores you need a graph that shows Ryzen with 2 cores enabled vs same Ryzen with 4 cores enabled, not two different CPUs with two different core designs.
                Well you are not right here Bridgman as this is real world test, artifical test on just one CPU does not prove anything in this case With that you will just pretending that everything is OK, but in practice it isn't...

                Your devs should really testing things with different vendor CPUs, as if you only testing on like you want here on one model by disabling cores you might be but could be also that you will never spot this amdgpu special issue which does not happen on nvidia driver

                Imagine average Joe, who currently have 2 core Intel and wanna buy 4 core AMD and to use amdgpu - from that POV things does not look good isn't it? He will improve performance with nvidia, but with amdgpu things will go worse - if that is not obvious

                The amdgpu+mesa stack as tested (not sure if "as-tested" enabled threading) can not take much advantage of the Ryzen's additional cores, and so the Pentium's higher clocks end up having more impact on frame rate than the additional cores.
                But nVidia driver takes advantage of that, just look at Openarena as example In comparison to 2 cores where results looks the same, you go down on 4 cores, but nvidia continue to scale up. Further look at Bioshock, Counter Strike and so on, same thing happens.

                To note again that glthread is enabled for Bioshock by default in mesa's drirc, but no that does not matter as same thing happens

                  Dengeon, we understand your point. A general consumer might be unpleasantly surprised that a CPU they bought with twice the advertised cores doesn't improve their frame-rate in games. But you keep saying things like "AMD's drivers go slower with more cores".. which, as it's stated, is (probably) false. But when someone tries to explain how that statement is false, you just repeat your first point, and throw in patronizing shit like..

                  ..to an AMD employee, as if your suggestion is some kind helpful insight that the entire technical staff at AMD just hadn't considered before.

                  I honestly now think you might just be trolling, like someone suggested earlier..

                    With these results here we can say - with amdgpu No, but on nvidia Yes.

                    But you keep saying things like "AMD's drivers go slower with more cores".. which, as it's stated, is (probably) false.
                    Yes it is false by common sense, but in some cases like this one it is true.

                    But when someone tries to explain how that statement is false, you just repeat your first point, and throw in patronizing shit like..
                    I am not generalising things here, it is just that this issue looks general since it happens in several cases.

                    I honestly now think you might just be trolling, like someone suggested earlier.
                    To me all this is so obvious, just you look at first picture i posted in this thread and read nothing else... else is just further explination for these who does not understand what they should look at on that picture



                    CPUs are changed and what happens there? Card X goes down, but Card Y goes up If purple looks OK to someone, to me it doesn't.

                      Drirc was supposed to do so in several of those games.
