    Phoronix: AMD's Radeon Gallium3D Starts Posing A Threat To Catalyst

    With recent milestones like the Radeon performance improvements in Linux 3.12 that come as a side-effect from a CPUfreq change, Radeon DPM, and the improvements found by the upcoming Mesa 10.0 release, and numerous other open-source driver improvements, the AMD's Radeon Gallium3D performance is very competitive to AMD's Catalyst driver. This close level of performance is for the R600 Gallium3D driver with GPUs like the Radeon HD 5000/6000 series graphics cards. Here's some benchmarks showing how the open-source AMD Radeon performance compares today to the closed-source Catalyst driver on Windows and Ubuntu Linux. In some of today's new data, the open-source driver was running 80%+ the speed of AMD's Catalyst driver.

    This benchmark is about the fact that the R600g driver has caught up with Catalyst.
    More modern graphic cards use the RadeonSI driver (that one, although it is making progress, is currently not at the same level as Catalyst).

    Michael explained it in the first paragraph of the article, actually.

    No Unigine benchmarks

    Nice work, however:

    1) The games used for benchmarks are obsolete. At least add Unigine Valley benchmark.
    2) Modern graphics cards are not included.

    Just want to add, that my radeon hd4570 is also getting to the point, where games are really playable. Even dota 2, which is based on relatively new technologies is getting closer to what it feels like on windows. It still has some graphics artefacts, fps is around 20-30 in average, but the game wasn't playable at all before.

    Thanks to open source drivers developers!

    Pre-evergreen asics do not have a native compute interface so you have to implement OpenCL over the 3D interface. Someone could write a helper lib to implement compute over 3D in gallium.

    +1 Thank you for catching this, and yes those people have egg on face.

    So how exactly are you freer than let's say in the Microsoft business model if everything is done by corporations? You would say that you can fork anytime, but can you actually do that? Can you take a 100 million LOC and jump right in writing code? If the code gets written by a big company, even if it's open source, you still get to do what they tell you since you don't have any manpower. It's just Microsoft with another name.
    You could, i don't know, contribute to the upstream project?

    Crazy, isn't it?

    Of course, if the people running the project don't take contributions, then there isn't a huge difference. That's exactly why a lot of people don't like the stuff Canonical is doing, for example, or the projects Oracle/Sun have taken over like OpenOffice. But even then, you can still download the source and make your own modifications locally, even if you can't support an entire fork.

    Really, come on. This is FOSS 101 stuff here. I know you're just trolling, but this is ridiculously stupid.

    buy a card that can use r600g. you won't be disappointed.
    Depending which it is. If you want to get UVD, an HD5xxx is probably your best bet: HD3xxx and older and the early HD4xxx series don't have supported UVD.
    If you wanted OpenCL, you would need an HD4xxx or later gpu.

    Actually Trinity and Richland are VLIW4 as well -- Llano and Ontario were VLIW5. Kabini is GCN.
