    Phoronix: Radeon RX 550: AMDGPU-PRO vs. DRM-Next + Mesa 17.2-dev

    Earlier this week I posted a number of Radeon RX 550 Linux benchmarks making use of AMD's popular open-source driver stack. For those wondering how the open-source driver compares to the AMDGPU-PRO hybrid proprietary driver for this sub-$100 Polaris GPU, these benchmarks will interest you.

    The time has come: Mesa driver better in any benchmark

      Cool. Last time when I trying mesa 17.0.4 on my radeon hd5850 it gives me worse performance than old fglrx :/ for e.g in Dota 2. In dota2 on fglrx (catalyst 15.9) I have about 50-60 FPS on almost max settings but on the same gpu with mesa 17.0.4 I have 10-25 FPS and horrible lags... Is any cause of this? Or maybe this is because open source not care too much about r600?

        Nope.
        Only in openGL.
        Not in vulkan.
        Not in openCL.

        AMD GCN users right now are in this very awkward transition phase where we have to pick and choose which userspace and sometimes even which kernel driver to use depending on the application.

          This is a historic moment...

          And it is time for the workstation customers to admit their defeat in their "closed source" driver philosophy.

          @humbug "Only in openGL. Not in vulkan."

          you just talk bullshit because: the OpenSource OpenGL implementation is faster than the closed source Vulkan implementation. so there is ZERO benefit in using Vulkan Closed Source right now for the end-user.

          you are right on this point: "Not in openCL." this should be the next big step in conquer and dominate the world by the opensoruce driver.

          after that AMD should stop the development of the Closed-Source driver on linux.
          we do not need it and we do not want it on our platform.

            Comparing GL to Vulkan performance is irrelevant when discussing Vulkan performance between drivers.

            Mesa doesn't support compatibility contexts in OpenGL, so hopefully AMD will continue providing closed-source drivers for Linux which do support compat contexts. Some games rely on them.

            I agree that Mesa is the best choice out there. But to say there's no need for the closed-source drivers is pretty absurd.

              I have a question. What stops Nvidia and other companies from using open source code in their closed drivers? That is if the code if better then their own.

                In my opinion, a better solution would be a single amdgpu.ko kernel module and multiple competing OpenGL/Vulkan/OpenCL implementations on top of the single kernel module. Currently, amdgpu-pro has its own kernel module incompatible with amdgpu.ko. airlied bridgman

                  Apart from ethics, either nothing or the open-source license used. If it's GPL then it's not legal to take the code, modify it and redistribute it with less rights than the original license provided.

                    A bit off topic but wasn't this generation of hardware supposed to give us HW accelerated VP9 ??
