Nvidia 6600 Series Examined 251

Posted by michael from the arm-and-a-leg dept.
DrunkenTerror writes "Yesterday at QuakeCon, Nvidia debuted their new affordable GPU mentioned a few days ago on Slashdot. Dubbed the GeForce 6600 and 6600 GT, they differ from their higher-end brethren by having only 8 pixel pipes (unlike the 12 & 16 of the 6800 line), and appear to be limited to 128MB of RAM. Both GPUs support Shader Model 3.0. The 6600 GT sports fast GDDR3 RAM, while the 6600 appears to use plain-jane DDR. The GT also supports the oft-recently-discussed SLI, which could 'enable millions of users to experience the power of two GPUs in their system.' The best part, however, may be the price/performance. With a suggested street price of US$199, the 6600 GT runs at a steady 42 FPS in Doom 3, at high-quality 1600*1200." Reader aceh0 adds a few links: "Nvidia is announcing their NV4x Sub $200 Level graphics hardware today with the GeForce 6600 Series. The 6600 Series is feature complete with the 6800s and the differences come in the number of pipelines and memory configuration. SLI has trickled down to the 6600GT as well. Coverage is available at Neoseeker, Tech Report and PC Perspective as well as other sites."

    Graphics processing speed no longer seems to be the primary limiting factor in games.

    I.E. I noticed a bigger jump in performance by upgrading my mainboard, cpu, and memory while retaining my relatively mediocre (but fully DirectX 9 compliant) graphics card, whereas my friend who had a similar configuration spent his cash on the latest Nvidia and didn't seem to come out significantly ahead.

    If you can afford all of the above, I suppose this is the card for you (hell get two and run them together). But too often gamers focus on the graphics to the overall detriment of their performance.

    • Which games are you specifically referring to, I'm 90% sure that people buying these 'now' are primarily looking for gaming rigs for Doom3 (heh as am I :)) and that from the reviews is heavily dependant on GPU performance

      Without mentioning system specs, this is a pointless post. Are we talking some guys coming from 800MHz P3s or do y'all have 2.4GHz machines?

      I'd suspect that your original CPU was somewhat lacking; 2-2.5GHz seems to be the the low end of what you can get away with for a respectable gaming machine these days. Once you reach this point, you're going to see a big difference jumping from your 5200 to a 5900.
    • Thats what I thought with doom3. So my coworkers and I all pitched in a few a bucks to buy doom. We wanted to see how it run on our dual xeon 3.06 ghz with 1gig of ram workstations. All I have to say it was unplayable with our quatro cards(still worth $300+ aka geforce 3 with line antialias).

      My box at home with a radeon9700 and 2.4 ghz P4 creams my workstation. 1024x768 on Medium, I can't even get 640x480 low to run smoothly on our workstations.

      • I think it is more like a little from column A and a little from column B.
      • That's because the Quadros don't take shortcuts that fuck up the image like consumer cards do. You can't afford to have your diagrams munged to get some extra fps. Gamers can, so that's what their cards do.
        • There are Quadro cards that use very old Nvidia chipset architectures. No amount of additional memory is going to make an NV25 (Geforce4 - 4x2 texel pipelines @ 300Mhz, ~10GB/s memory bandwidth, DX8 features) perform like an NV40 (Geforce6800 - 16 pixel pipelines @ 400Mhz, ~35GB/s memory bandwidth, DX9 compatible). Newer chips have more pipelines, more memory bandwidth, more advanced geometry engines, and run at higher speeds.
    • "Graphics processing speed no longer seems to be the primary limiting factor in games."

      Try playing 1600x1200 with 4xAA (or higher)... then see how your graphics card isn't the limiting factor :).

      Even with no AA, FS2004 can get my Radeon 9500 Pro down to 10 fps or less in heavy weather at 1600x1200.
    • It depends on the resolution you're running the game at. If you're running Doom 3 at 800x600 on a 6800GT then the CPU *IS* almost certainly the limiting factor for the framerate; you would probably see the exact same fps on a 5900. However, moving up to 1600x1200 (or above) and the rate's going to drop as the graphic card struggles to render the much larger images (the CPU is doing pretty much the same work as it was at 800x600).

    US$199, the 6600 GT runs at a steady 42 FPS in Doom 3, at high-quality 1600*1200

    In the end, regardless of what memory is being used, and what technologies, if I can play the newest game at its highest level of graphics at 42fps, then I'm a happy gamer, especially when the price is under $200 (USD).

    • The highest level of detail in Doom 3 is "Ultra" mode, not "High." Ultra requires a video card with 512MB of memory. Basically the difference between ultra and high is the use of completely uncompressed textures in ultra. I'm sure there's other minor differences, but not many.

      In fact, I've played Doom 3 at all 4 levels (low, medium, high, and ultra). The game looks damn near identical all the way through. You have to look pretty close to see differences.
    • Does anyone remember the scandle a little while ago when Half-Life2 came out and the NVidia cards were doing all sorts of crazy things to show misleading frame rates (like special optimizations only for HL2 framerate tests, etc). I imagine that thiese are real frame rates, but I wonder.

    • The chip is native PCI Express. NVidia apparently is betting on the success of a second chip that they made for AGPPCI Express translation. The chip can operate in both directions and thus older GPUs can use this chip to work with PCI Express boards and this new 6600 GPU can use this same chip in the other direction to work with AGP boards. I wonder how much of a slowdown this chip brings though.

    Not to take points away from the article, but if you're looking to get a graphics card, take a peek at Nvidia's 6800 GT.

    16 pipelines AND it can *easily* be overclocked from it's 350Mhz core / 1000 Mhz memory to the 425/1100 speeds of a 6800 Ultra (which is $150 more).

      No, neither you nor they would be better off. Companies like nVidia and ATI rely on the quick infusion of lots of cash from the early adopters to fund R&D on better GPU's. If they sold their best chips at the same cost as an FX5200, funding for innovating these great chips would dry up and you'd have to wait much longer for new designs and better performance.

      The best way to get these companies to reduce their costs is simply not to buy their equipment. The laws of supply and demand will naturally produce an equilibrium in which they sell their products at a price point that maximizes their own profit. If their best cards are $500, then you can be assured that there are enough people out there willing to pay $500 to make it more profitable for them to sell it for that price than for $499, $250, $120, or $60. If you aren't one of those people willing to pay $500, then either (a) produce your own damn GPU or (b) wait for the prices to come down. Either way, stop whining.
    • There is a significant chance that the 6600 is a way of salvaging "reject" 6800s in which one or more of the pipelines failed QA. (Possibly because of a dust speck or other such problems - Even in the cleanest of clean rooms there are still contaminants, which is why IC yield is NEVER 100% and is typically lower the larger the chip is.)

      Solution: Rather than just junk the entire chip, disable the pipelines that don't work and sell the chip as a lower-performance one with the pipelines that do.

      I've explained this before, and I'll do it again. Television and video have motion blur-- the effect of the capture device essentially "averaging" the motion that occurred across the duration of capturing that frame.

      Video cards generate a crisp, instantaneous frame that represents only the precise instant the frame was rendered, not the whole time the "shutter" was open.

      At a *bare minimum* producing motion that looks as smooth as blurred 24fps requires double that. (You have to have two frames for your eye to blur between) To do it as well as a film camera requires even more, since their motion blur is effectively an infinite number of samples averaged together over the duration the shutter was open. I'd guess you could get a reasonable approximation at 3x the framerate.

      TV and Movies are also filmed with the 24fps limitation in mind-- good cinematographers are well aware of the limits and know how to avoid situations that would result in jerky movement.
      • At a *bare minimum* producing motion that looks as smooth as blurred 24fps requires double that.

        The simplest example I give to people who say '24fps is enough' is to tell them to wave their mouse cursor around onscreen as fast as they can. The cursor image is being updated at at least 30fps (more like 60fps), yet you can still see discrete cursor images with gaps between them as opposed to one smoothly-moving cursor.

  • You know, if my GF4 Ti4200 had SLI capabilities that would make my life much easier right now. i could step up the whole level of graphics performance in my system by a VERY noticeable margin. i look forward to these new cards because it means by the time my $200 video card is going the way of the dodo I can shel out $75 or whatever and add a second one and viola, extended life.
