    Phoronix: AMDGPU vs. Radeon GCN 1.0/1.1 Performance On Linux 4.9 DRM-Next

    With the forthcoming Linux 4.9 kernel there is experimental AMDGPU Southern Islands support so that original AMD GCN 1.0 GPUs can optionally work with the newer AMDGPU DRM driver rather than the mature Radeon DRM driver. In this article are tests of some AMD graphics cards from GCN 1.0/1.1 era comparing the performance impact of switching the Radeon/AMDGPU kernel driver with this DRM-Next code for Linux 4.9.

    Maybe we can make anniversary celebration - 2 years CIK being experimental and SI unstable since its release

      Some look ugly. 33 fps vs 22 fps is a huge difference between "okay" and "totally unplayabe".

        And missed to comment about this:

        ... while in a separate article will be Radeon R9 290 (Hawaii) benchmarks due to its regressed state.
        Well, Hawaii was never high priority

          To summarise - other then regressions, article looks boring

                anything below 100 is unacceptable for an FPS game. Also communist network code is unacceptable for an FPS game, which includes Overwatch and NS2.

                  I can confirm the same results for radeon vs amdgpu on hd 7970

                    I wonder if the issue with 1.1 is dpm.
