    Phoronix: AMD Fusion Linux Gallium3D Performance Has Improved A Lot

    The performance of the open-source AMD Radeon Linux graphics driver for AMD Fusion APUs has improved a lot, but the Gallium3D driver performance still isn't yet on par with the AMD Catalyst binary driver. In this article are a variety of tests from an AMD APU including with the Linux 3.11 dynamic power management support, Mesa Git, and when using the R600 SB shader optimization back-end.

    Nice, although I really would have liked to see a power consumption graph as well...

    Open source DPM would be the same as Catalyst if previous tests are any indication. Without the DPM, power consumption would be allot higher.

    The last chart suggest something is seriously wrong in the gallium driver, if fixed could boost all other benchmarks.

    Default Question for Bridgeman:

    Question for Bridgeman:

    Kaveri APUs and later, will have a unified ram architecture. They will also include a GCN gpu core, and iirc GCN has hardware shader scheduling(i may be wrong on this though). I believe memory management and shader scheduling are those difficult tasks to optimise for opensource devs. Does it mean that opensource drivers will need less optimizations in order to have similar performance to Catalyst on newer APUs?
