  • Intel G45 VA-API (pitiful) benchmarks

    Copy-paste from intel-gfx mailing list:

    Hi,
    I did some benchmarks on my Samsung X360 laptop.

    The cpu:
    model name : Intel(R) Core(TM)2 Duo CPU U9400 @ 1.40GHz
    stepping : 6
    cpu MHz : 1401.000

    The sample video (89 seconds, 80 MB): http://download3.dvdloc8.com/trailer...um_trailer.zip

    Video Type: 1920816 (1080p), 23.967 FPS, CE-Baseline profile (PS3 and Xbox 360 compatible)


    Multi threaded decoding:

    mplayer2 -vc ffh264 -lavdopts threads=3 -benchmark -nosound <file>

    Time elapsed: 28.313s



    Single threaded decoding:

    mplayer2 -vc ffh264 -lavdopts threads=1 -benchmark -nosound <file>

    Time elapsed: 38.774s



    vaapi (kwin desktop effects ON):

    mplayer -vo vaapi -va vaapi -benchmark <file>

    Time elapsed: 205.888s



    vaapi (kwin desktop effects OFF):

    mplayer -vo vaapi -va vaapi -benchmark <file>

    Time elapsed: 198.548s




    CPU USAGE: http://files.linuxsystems.it/temp/20...-cpuusage.jpeg

    First one from left is multithreaded, second one is single threaded, third is vaapi with kwin on and last one is vaapi with kwin off.
    Note that even when it quits mplayer at the end of the vaapi tests it keeps using the cpu for some time (you can see it in the screenshot).


    Full log: http://files.linuxsystems.it/temp/20...45-fulllog.txt


    Hopefully one day vaapi on g45 will work properly and I will be finally able to watch high bitrate movies on my laptop :|


    Cheers,

    New patches, new benchmarks
    Now testing http://cgit.freedesktop.org/libva/ g45-h264 branch + patches from vaapi/intel-driver (http://cgit.freedesktop.org/vaapi/in...og/?h=g45-h264).

    Here are the 5 patches:

    Time elapsed: 66.489s



    vaapi with patches (kwin desktop effects OFF):

    Time elapsed: 55.239s



    Much, much better but still slower than single threaded decoding, not talking about multi threaded...
    I did not test it with Swapbufferwaits Off, because it's meant to avoid tearing and nobody wants to disable it while watching videos.
    Anyway the whole graphic stack was the latest and the greatest from git. I will test it with a more demanding source (high bitrate blu ray rips).

      And here is a video my laptop just can't decode: http://www.sendspace.com/file/qv2ws9 (86 seconds, 200MB)

      Multi threaded decoding:

      mplayer2 -vc ffh264 -lavdopts threads=3 -benchmark -nosound <file>

      Time elapsed: 82.641s



      vaapi with patches (kwin desktop effects OFF):

      mplayer -vo vaapi -va vaapi -benchmark -nosound <file>

      Time elapsed: 104.122s



      The video lasts 86 seconds, so current vaapi implementation isn't powerful enough to decode it, but we are going in the right direction!
