    Default Intel Linux Graphics Performance Q4'08

    Phoronix: Intel Linux Graphics Performance Q4'08

    The past year has brought several invasive changes to the Intel Linux graphics stack with the introduction of the Graphics Execution Manager for GPU memory management within the kernel, support for the Direct Rendering Infrastructure 2, and kernel mode-setting finally getting ready to enter the limelight. How though has the work this year affected the overall performance of Intel integrated graphics on Linux? In this article we have run a few benchmarks that show where the driver was at a few months ago and where it is today.

    Ouch! Can something like that be posted so close to Xmas?

    Damn, a friend is looking to buy a 4500-based laptop, but with this kind of performance it will be unusable.

    Michael, can you comment on regular computing tasks? Can the driver play fullscreen video? Is compiz usable (e.g. when browsing the web)?

    Much in X is in a transition period that has started a few months back and will come to a close in early 2009. Most of those exciting things you read about on phoronix will be delivered for intel cards first, thanks to openness and good support! For now, you can use an older X (no one forces you to use Ubuntu alpha releases) and simply wait until the dust has settled.

    But even if you go for unstable stuff, in my experience, all recent snapshots of mesa, xorg, intel drivers, etc. are good enough for compositing (i.e. compiz or kwin) if you play a little with xorg.conf. Moreover, your favorite distro will probably avoid the more problematic releases.

    I find it pointless to publish benchmarking results from the Ubuntu development version just a few days after its introduction of a new major version of the xserver and other bits. At this point, you're happy if the Xorg stack builds and runs. Now comes a period of ironing out compatibility issues and other newly discovered bugs before performance can be optimized.

    To compare intel 2.4 vs 2.5 I can suggest the intel 2.5 and corresponding libdrm packages for Ubuntu 8.10 in the "intel-gfx-testing" PPA (see the ubuntu-x mailing list for details). These packages have not been thoroughly tested either, but at least the Xorg base will be the same so there is a better chance the performance difference is actually due to the driver.

    Can I? From what I've picked on Phoronix, Intel's 4500 IGPs are only supported by the new 2.5 driver, which *I think* requires the latest X and Mesa.

    Since this is not my system, I'd very much prefer to put stable software in it. However, if this is a choice between bleeding edge software and a vesa framebuffer, I'd have to go the bleeding edge route.


    @allquixotic: Please post your results!

    I got one of these 4500HD here and it's perfectly fine with the 2.4.x series. Ubuntu 8.10 is perfectly ok. (Even if it doesn't have xvmc)

    Replace "Ubuntu alpha releases" by "Intel IGP" in his post and you got your answer

    All jokes aside, I'd love to see the results of improvements they made with their new drivers. I guess it shouldn't be that long now.

    I'd *love* to, but we decided to go with a good matte monitor instead of a video card. Finding a good-quality laptop with a good monitor, video card, size and a reasonable price is an exercise in frustration. I just hope the 4500 lives up to the hype (that is, it offers usable 2d and video with Compiz).

    @lucky_: Many thanks, I am relieved it works with 8.10 out of the box! Performance is likely to go up as drivers mature, as was the case with the X3100 between Ubuntu 8.04 and 8.10.
