    Not to nitpick, but the introduction comment about nvidia dominating ati at the midlevel is not right. The 7600 and X1600 Mobility were competitive with each other. The mobile version of the 7600 had only 8 pipelines, instead of the desktop version's 12. Consequently, depending on the game, one was faster than the other or vice versa. This was extensively benchmarked on notebookreview forums. Reply

    All I know is I have an Mobile X1700 and a Go 7700. The latter spanks the heck out of the former. (That would be the ASUS A8Js vs. the ASUS G2P.) Reply

    I think the workstation column is wrong. For series 7, the workstation lineup is 350M (low end), 1500M (midrasnge) and 2500M, 3500M (high end, 3500m is an overclocked 2500M) as follows:

    NVIDIA_G71.DEV_0298.1 = "NNVIDIA GeForce Go 7900 GS"
    NVIDIA_G71.DEV_0299.1 = "NNVIDIA GeForce Go 7900 GTX"
    NVIDIA_G71.DEV_029A.1 = "NNVIDIA Quadro FX 2500M"
    NVIDIA_G71.DEV_029B.1 = "NNVIDIA Quadro FX 1500M"
    NVIDIA_G72.DEV_01D8.1 = "NNVIDIA GeForce Go 7400"
    NVIDIA_G72.DEV_01DA.1 = "NNVIDIA Quadro NVS 110M"
    NVIDIA_G72.DEV_01DC.1 = "NNVIDIA Quadro FX 350M"

    The known released GPU IDs for 8xxxM are as follows

    NVIDIA_G84.DEV_0407.1 = "NVIDIA GeForce 8600M GT"
    NVIDIA_G84.DEV_0409.1 = "NVIDIA GeForce 8800M GS"
    NVIDIA_G84.DEV_040D.1 = "NVIDIA Quadro FX 1600M"
    NVIDIA_G86.DEV_0425.1 = "NNVIDIA GeForce 8600M GS"
    NVIDIA_G86.DEV_0427.1 = "NNVIDIA GeForce 8400M GS"
    NVIDIA_G86.DEV_0428.1 = "NNVIDIA GeForce 8400M G"
    NVIDIA_G86.DEV_0429.1 = "NVIDIA Quadro NVS 140M"
    NVIDIA_G86.DEV_042B.1 = "NVIDIA Quadro NVS 135M"
    NVIDIA_G86.DEV_042D.1 = "NVIDIA Quadro FX 360M"

    That makes the 1600M a replacement for the 1500m, based on 8600GS and midrange ('performance'). The 5700 should be under 'mainstream'. The enthusiast or perhaps 'heavy cad' cards - the replacements for the 2500M and 3500M - are, just like the enthusiast gaming cards, not released and likely waiting for a die shrink.

    I'm going by the classification NVIDIA gave the various cards on one of the slides. Note that existing products are not included in the tables, only the new stuff, so outside of the mGPU parts (business) all of the cards are presumably DX10 capable. I would expect that the "enthusiast" 1600M is no faster than the other 8M parts listed, but there were no details on clock speeds or features of the workstation chips. I'm not sure any of the workstation parts listed are even shipping yet; most likely they are only being announced right now pending actual use in notebooks. I can check with NVIDIA for more details on those parts, though.... Reply

    http://www.nvidia.com/object/IO_42274.html">More details on mobile Quadro cards are available here. Basically, they are all DX10 parts, and the 1600M will probably be similar to the 8600M GT. Possibly it will be tuned such that the performance offered in workstation apps will be worthy of inclusion in the "enthusiast" range, although I'd say "workstation enthusiast" is a bit of an oxymoron. :) Reply

    Thanks for the link. And yes, its the same for mobile workstation cards as for mobile gaming cards: the top performing ones ('enthusiast' or 'serious cad user' or just lets say 'expensive' :) ) have not been announced yet as the hole in the model numbers shows. They will likely need a die shrink to get the heat down for mobile use. So the 7xxx series still hold top place for mobile.

    Plus of course the workstation models will be released a little after the gaming ones, due to the need for ISV certification.

    I believe Duke Nuken Forever should have been on that list :) Reply

    Oh, it will be DX10, but that's a "most anticipated game for 2010". LOL

    (I actually have no idea when it's coming out or if it will be DX10.)

    Any inkling or hints from nVidia that Apple might have picked a 8 series chip for the inevitable MBP refresh next month? Reply
  • JarredWalton - Thursday, May 10, 2007 - link

    No idea, although since Mac doesn't use DirectX for graphics and may not really matter much. Those who want to use a MacBook Pro and run Boot Camp could potentially benefit if they run Windows Vista, but for now I wouldn't count on Apple using the new NVIDIA parts. I could of course be wrong, as I don't really stay up-to-date on Apple plans. Reply

    I like mGPU for several reasons. Not only for laptop but also for desktop or other application.
    It allows you to run Vista with Aero. This is good enough for for most people who only want fast Interface.
    VP2 would bring Full HD H.264 Decoding to the mass.
    Combing with low power usage this is very good things like AppleTV.

    Are mGPU only available on Laptop but not desktop? It would make a very cost effective PC for the mass.

    Any news on whether we will finally see DL-DVI support on all but the high-end / 17"+ laptops? Reply
  • JarredWalton - Wednesday, May 09, 2007 - link

    When I get one of the 8000 notebooks I'll be able to verify if that's supported. I think it's an option but it's up to the notebook manufacturers to support it. Reply

    Any other wrongly listed games?

    Given Carmack's support of OpenGL, he might be using DX10 type fragments shaders in that manner. Obviously, the slide is provided by NVIDIA, so whether it's accurate or not is up to them. Supreme Commander is listed, and yet that's "DX10 via forthcoming patch" which is a bit obscure. Reply

    The slide has now been updated with a more current list of upcoming DX10 games. Reply

    "We do have an early Santa Rosa notebook in-house for testing that's equipped with a GeForce Go 8600M GS, but unfortunately we've run into some difficulties during testing and won't be able to bring you actual performance results for a bit longer"

    Heavy sigh.
