    Intel Releases 965/G35 IGP Documents

    Phoronix: Intel Releases 965/G35 IGP Documents

    At the Linux.Conf.Au conference today, Intel has announced NDA-free programming documentation covering the 965 Express and G35 Express integrated graphics processors (IGPs). Intel's display driver has long been open-source, but up until now, they have not been releasing the programming documentation for these products to the public. This move comes months after AMD announced their new open-source strategy and began releasing register documentation on their R500 and R600 GPUs.

    Oh yes. Well, I ended up getting the Gigabyte P35-DS3L without integrated graphics, and putting my best two pci cards in for a dual screener. Saved 40$ when compared to the G33 board.

    I'm going to get a mobo with G35 soon too. It would've been G33, but the model I want has been out of stock for months. So I'll just wait for the improvement of X3500

    Hmm. Didn't Intel claim the X3500 will archieve double 3dmark score compared to X3100?
    Eh, no... It's the one AFTER the X3500 that'll be 2x faster. Actually it'll be 1.7x faster Intel says. X3500 has no perceivable architectural difference from the X3000. Hell, can anyone tell me what advantage X3500 has over the X3000 other than that it supports DX10?? I think DX10 support is just disabled on the X3000, so there's really no difference at all.

    X3100 is laptop, btw.

    Does this mean that the drivers for the 965 IGP will improve? Because I have a friend with that mobo, and a lot of games crash or can't run (for example, Regnum Online), while with his previous mobo(also an Intel, but it was 850 I think) it was working fine..
    I was really disappointed at Intel :P

    Yes. It's their first relatively credible IGP part. The X3000 and X3100 fell a bit short of that. I wish I had a better budget for things- because I could get one right now if it weren't for all the other things I need to be buying, including getting my roof fixed.

    does the document release include thespec for the Clearvideo hardware, so the FOSS community can make use of hardware video acceleration?

    Heh... On paper, they're nice parts. The biggest problems with their real use in gaming is partly that we've not had a lot of stream processor development under our belts to know how to really optimize the shader operations needed for 3D rendering coupled with the hamstring of UMA operation. (Even WITH good drivers, the X3000/X3100 have been still lackluster- though vastly better than the past offerings. The X3500 is the first "real" contender in the IGP space from Intel- and we're still going to be fighting the uphill battle of the stream processor execution optimization for a while yet.)

    In the end, I think having the tech data, including how to drive those shaders through their opcodes, will end up being a boon. Right now, I'm seriously considering getting a G35 chipset motherboard to play with and see what all I can tweak. If I had AMD's stuff right now (hint...hint...) I would already be DOING it with machines in hand since I've got several R300/R400/R500 boards in hand. Heh... It's probably better, short term, though, as I've got too damn many irons in the fire already...

    Intel isn't using that project to get into competition with AMD and Nvidia.
    Of course they are. Those are Intel's main competitors in most everything they do.

    It's just that it's confusing that Intel is not aiming for peak DirectX 10/11 gaming performance. Which is fine with me, that's not something I particularly care about.

    The GPU is not just for accelerating games anymore. It's a co-processor that can be used to augment the overall performance of your machine. What runs on top of them is software like anything else... and Intel seems to be aiming at making their GPU easy to use for lots of different tasks in addition to gaming.


    According to Mesa's site, they're advertising 2.1 support where it's available and since the bulk of support isn't in the driver layer but in the API layer...
    Ya.. OpenGL does not work like DirectX. If Mesa supports 2.1 then all the drivers that are based on that version support 2.1 also, more or less.

    What matters is how much of the API the graphics card accelerates and how well it can do it.

    The GMA X3000 and GMA X3100 are the most advanced IGP that Intel is offering at this time.
    It supports pixel and vertex shading model 3.0. It can do Anisotropic filtering up to 16 times. It has a theoretical fill rate of 1067 megapixels/s and 2133 megatexel/s at 667mhz.

    This puts it roughly on par with NV40 (Geforce 6) in terms of hardware features.

    Does this mean that it will perform on par with Geforce 6 stuff? Nope. 'fraid not. Gaming performance of the GMA X3100 on Linux right now is best described as 'lousy'.

    If your a open source purist (I am a dirty purist ) then that means that if you restrict yourself to open source drivers then Intel will outperform Nvidia at any time. But if your going to use Nvidia's proprietary drivers then Nvidia will provide a night and day performance increase over any of nvidia's offerings for any remotely modern Nvidia card.

    If your gaming requirements are light (Intel GMA X3100 can drive 'Return to Castle Wolfenstein' comfortably), you only want a 3D desktop, or your aiming for best power management features (for a laptop) and that sort of thing then I'd recommend getting a Laptop with Intel IGP.

    Otherwise if you want gaming performance then a low-end Nvidia card will serve you much better.

    Well, the Larrabee will be a huge gift for video encoding/decoding.
