    Phoronix: 11-Way Low-End & Older Open-Source GPU Linux Comparison

    In finding it interesting that the Radeon HD 8210 Gallium3D performance can outperform Catalyst from an AMD E1-2100 "Kabini" low-end APU, which was tested on an ECS KBN-I Kabini system that can be found for just over $30 USD when on sale, it's time for some more Linux benchmarks. The latest tests from this low-end but fascinating platform are benchmarking a variety of PCI-E graphics cards on this AMD Kabini platform using the open-source Radeon and Nouveau graphics drivers on Ubuntu 14.04.

    That sounds to me you write a patch then .

    Just kidding... maybe i will do if i got time for that or maybe developers get fixed it in the meantime especially if newer radeons are also affected .

    Do you use r600g or radeonsi? r600g shouldn't tear in XV unless you explicitly disabled vsync, glamor, well, its other name is tearing until someone creates a new GL extension.

    So doesn't metter, if someone want to try to play these with any radeon (i am not sure is there also some difference in CPU usage?) and if it is global regression that is more arguments for me to fill a better bug . For example some of these with kernel 3.13 i 3.14 using gl output:

    http://samples.ffmpeg.org/game-formats/idroq/

    Code:
    mplayer -vo gl http://samples.ffmpeg.org/game-formats/idroq/jk02.roq
    Is there some difference in CPU usage with 3.13 and 3.14 kernels no metter whatever mesa version is ?

    I wolud like if someone with radeon can try to play some video with mplayer using gl video output:

    HTML Code:
    mplayer -vo gl some.file
    With 3.14 and 3.13 kernel and to watch CPU usage.

    For me in 3.14 CPU utilazation is doubled (45% more) . xv output not affected, but i not use it because of diagonal tearing and subtitles is not good like with gl .

    Also in most gl games when some video is played it use more CPU like with that mplayer example .

    hd3850 agp

    Is it possible to bench ati HD3850 AGP, one of the best if not the best latest AGP card ever? It should outperform the hd4670. Thanks.

    All of the tested graphics cards were easily CPU bottlenecked when running World of Padman on the AMD E1 Kabini APU system. Why these results are being shown though is that while CPU bottlenecked the Nouveau performance was slightly better than the R600/RadeonSI Gallium3D performance, due to potentially lower CPU utilization.
    Running Xonotic with low quality image settings showed the GPUs again being bottlenecked by the low-end dual-core AMD APU, but it's interesting to show again the GPUs with the Nouveau graphics driver were running faster than the R600/RadeonSI drivers when being CPU bottlenecked.
    I also spotted that high CPU utilazation with 3.14 kernels in some games at cartain places with older r200 radeon too, 3.13 was better .
