    I'm not conviced this will help that much for Intel GPUs. Developers from Intel have been optimizing shader compilers specifically for Dota 2 for some time without much impact on performance.

    This is very nice work, but it fixes the symptoms, not the cause of problems. Dota 2 for Linux, probably because of how ToGL implements shader translation uses 2x more memory than the Windows...

    Improvement of 4% in performance in some games in not really minor:

  4. Samsung Galaxy S2 vs Linux PC performance (RAM bandwidth)

    Hi guys, I made some software to compare RAM bandwidth Android phones to Linux PCs.

    Here are some results:

    ~5400 MB/sec - Intel Xeon X3430, DDR3 memory, under moderate MySQL load( 2009)
    ~2200...

    waqas300, please restart your machine after installing fglrx to make sure that the "radeon" kernel module is not loaded, as it will interfere with FGLRX.

  6. Great benchmark!

    Thank you Michael!

    It would be nice to compare it with some CPU. So we can actually see if low end cards make sense for that processing work.

    I'm not sure which OpenCL CPU implementation is...

    Radeon 58xx vs Fermi

    I saw that 57xx doesn't have double floating point precision support, so 57xx is out of the question for me. Will OpenCL implementation from AMD support double floating point precision emulation...

    I'm interested if the OpenSource drivers downclock the GPU properly as they should to save power?

    It's strange that ATI didn't work with folding@home to fix such a high profile GPGPU application.

    I guess everything will be better and easier to fix when we have both opensource OpenCL...

    I'd be very happy with a more power efficient, 40 nm version of a 3850, updated to be better suited for GPGPU work, with even more circuits for power and clock gating.

    I don't know how much my card alone spends in idle. I only have the complete system numbers: 82 WATTS on a P35 E8200 system. 160W in peak load (Furmark 1.7.0 running under wine )

    But still I...

    Some time has passed, 5xxx series is here, so I have a couple of quick comments regarding this. The comments are not Linux driver specific, and I hope you don't mind.

    1. Let's hope OpenCL support...

    ATI control center or whatever's the name of the application. There is temperature monitoring somewhere, at least for my X1950Pro.

    0xE008 and 0xE00C doesn't work because that memory is not mapped in the radeontool source code.
    This is the line:
    radeon_cntl_mem = map_devince_memory(base,0x2000);

    So it only maps first...

    Performance reduction or temperature reduction? Or both? EDIT, Ok I see from the logs in pastebin. Strange, I guess the driver is modifying those. What's the rough idle temperature difference between...
