    Default Radeon DRM GPU Driver Performance: Linux 3.4 To 3.8

    Phoronix: Radeon DRM GPU Driver Performance: Linux 3.4 To 3.8

    Last week benchmarks were delivered on Phoronix that showed the Intel DRM GPU driver performance between the Linux 3.2 and 3.8 kernels. In this article are similar benchmarks of the Radeon DRM driver in recent kernel releases using AMD graphics hardware but going back only to the Linux 3.4 kernel due to show-stopping issues.

    FYI 3.8 also give you hyperz ...

    How much can we trust this benchmark if recent comparisons are showing very clearly that Unity can have unpredictable influences on 3D performance?

    Nah, i was hope to see supertuxkart 0.8 test on radeon, but nope. Is this true or not .

    So, has there been any word to explain the problems with both Prey and Nexuiz here (assuming it is not something like AA being triggered)? Everything else is indeed looking good.

    On a HD4650.
    This is an oooold and slooow card.
    Kind of useless benchmark again...

    To the fullest extend, since Unity was used like it's used to all the way through the entire benchmark? (duh...)

    Prey and Nexuiz performance can be explained by actually studying the articale.

    - kernel v3.4 makes radeon advertise mesa version 2.1
    - kernel v3.5 and higher makes radeon advertise mesa version 3.0

    So you know how exactly the problems with Unity are caused and that the version (and therefore functionality and different state of bugs) of the driver has no influence on the performance regressions of Unity?
    If so, please share your insight into that with the Unity developers, so that it can be fixed.

    No I don't. Never shared, never claimed to do so.

    I'm implying that the use of Unity is not an issue since it's consistently used during all the benchmarks. So the (relative) numbers are accurate. If a benchmark is faster with Unity, it will highly likely also be without it. I'm was stating that argueing about is kind of nonsense. Unity is not the only factor influencing video performance.

    Furthermore, if it would then that would indicate a buggy driver and that the hypothetical inconsistent results cannot be blamed by wrongdoing of Unity.
