    Phoronix: RadeonSI OpenGL Performance Has Evolved A Lot Since Early 2015

    Yesterday I posted some benchmarks showing how the AMDGPU / R9 Fury performance has jumped up in the past few months just since the April release of Ubuntu 16.04 LTS. For those wondering how the open-source AMD OpenGL performance has evolved over the longer term, I took a Radeon R9 270X graphics card and re-did tests going back to Ubuntu 15.04 for looking at the RadeonSI Gallium3D performance for the past year and a half.

    Great evolvement of GCN 1.0, probably most problematic cards during this period

    And now all that GCN 1.0 investment, will be restarted with amdgpu

      Unigine Heaven seemed to have better performance on Ubuntu 15.04 than 15.10/16.04
      Because it didn't support Tessellation before Mesa 11.0, and Tessellation performance was abysmal until optimized code came in with the 11.2 release. That is, if you test Heaven with Tessellation enabled at all, otherwise it would be a strange regression.

        Yeah, mesa 11.0 doesn't support opengl 4.0 for radeon... maybe problem was kernel or so. r9 270 was nasty gfx IIRC

          How so? The OpenGL driver is still the same.

              It is not the same, just name is the same... cos of first name X convention

                It's about 95% the same.

                  Hello phoronix,
                  I thank you for having made a complete and tested this with the same map-grahique which is r9-270x.
                  I will like to have a tutorial for installing the graphics driver under Xenial, at home it not.
