SLI Performance Reviewed at Anandtech 45

Posted by Zonk from the two-chips-means-twice-the-shiny dept.
DarkSarin writes "Anandtech has a review of dual gpu's using nvidia's nforce4 SLI chipset. They are showing ~66 fps on doom3 at 1600x1200 with 4xAA turned on (a 75% increase in performance over a single gpu). It's not available yet, but it should be fairly soon."

    I wonder how many of us are actually going to shell out for new graphics hardware. We are kind of hitting the wall in performace here already.
    • Not until the hardware is pushing 100FPS with all the eye-candy on at the highest settings and at the highest resolution your monitor could possibly do.

      No walls, except those made out of cellophane.
    • We are in no way hitting the wall in performance.

      Perhaps you meant that we are hitting the wall in terms of the price/performance curve, with which I agree 100%. Most of us cannot justify the cost of these new cards, given the associated performance increase.

      Then again, this really isn't anything we all don't already know.

        No one is telling the parent poster to go out and buy these cards, and buy this hardware. Yes, it is being marketed (since "reviews" are really just a cheaper way of marketing for these people), but no one is making up your mind for you to plunk down two wads of cash for two graphics cards.

        This is the typical outburst that I hear from the lemmings that line up for plastic, and buy what the television tells them to buy. :ugh:

    • I agree with you, but having the cutting edge equipment never scales in "bang-for-the-buck."
    • 2.5 times the price for 1.75 times the speed is a quite good ratio for a very high end upgrade.

      An athlon 4000+ costs almost 3 times as much as a 3400+ with a less than 20% increase in speed. (and a dual cpu upgrade won't help in any game)

      The point made at the end of the article is that even if you can't afford two now, you can get one, and in 6 or 12 months not only will the current top of the line be cheaper, but you can get a huge performance increase by just buying an extra one (and maybe a bigger power supply) instead of replacing your current card entirely.
      • We've been talking about this at my local LAN group. I just don't buy into it. In 6 months, the top of the line game will be optimized for UberPixelSlamin 3.75. Your card will only support 3.70. So, now you have a choice: spend more money to do SLI and still not have the features you want; scrap the card and buy one that does have features you want.

        Look at it this way. I just bought a FX5900 in January. I can't remember what I paid, but I know I saved up for a while. Now they have these 68oo thingie

          That's a pretty big cunt hair [anandtech.com] you've got there.

          Also, Nvidia must have really taken a step backwards to have knocked bump mapping out of the FX series, considering that environment bump mapping has been in cards since the Matrox G4

          • Selective benchmarking? You picked the biggest difference you could find.

            NWN has less than a 10fps differnece.

            FFXI is only about 1000 whatevers slower.

            Wolf:ET is about 10fps slower.

            UT2k4 is also about 10fps slower.

            Also, all of these were run at 1280*1024. Running at the more common 1024*768 would close that 10fps gap quickly.

            Yes, my card does have bumpmapping. I was just being an asshole about features like PixelShaders and "full Dx9 compatible" which seem to be artifically gimped on older generati

            • Halo is a shader/video card bound game, just like almost all future graphically impressive games will be, like doom 3 is, like HL2 will be. NWN, all the Q3 engined games, and UT2K4 are far less video card bound, relying much more on the CPU.

              They test at that res to try and get away from games being CPU bound and actually test the performance of the *card*, not the system it's in, testing the CPU in video card reviews offers less differentiated graphs, for some reason :-P.

      • Nah, that's not going to work. Pairing any two components that aren't bought at the same time never works well. SLI is about having better performance than you can get from one of the top of the line cards.
    • a.) It's not NVidia's fault you'd have to buy a new mobo.

      b.) if you really need the performance that bad, you'll be hard pressed to spend 2x on the card and find a >75% faster card that uses only one slot.

      c.) It's optional, not expected.
    • A lot of the tests are limited by the CPU, which becomes very apparent with such a ridiculous amount of graphics power. The amount gained depended upon the game (notice that in Far Cry, for example, there was a 105% gain for the 6800GT at 1600x1200, 4xAA).
    • Yes. SLI allows you to get better performance than is possible with the best single card. If you want the best 3D framerate you can get, the solution is SLI. It doesn't matter that the overhead means you don't double your performance, there's no other way to get performance this good.

    Yeah, it's expensive, but cost has never really ever been the point. Having the fastest computer is.

    I totally undestand how some of you guys wouldn't spend that kind of cash on an SLI system, you just want a sensible computer for everyday use. Well, guess what? I don't. I want the highest framerates possible, so when I play my brother online in Halo or Doom 3 deathmatch, I can SPANK HIS ASS.

    I think that nvidia bringing back the SLI upgrade path is not only sensible, it's FUN. And that's the point.
    • Well, anything over 60 FPS is not going to help you anyway. The eye can't see much over 60 FPS. A dual card setup will allow you to run Doom III at very high detail levels though. If you want to run a game like Doom III with everything turned on then by all means buy two video cards. Graphics just don't mean that much to me, I don't mind turning down the detail levels a little bit.

    There's a very simple reason why this SLI is so desireable by the marketing types at NVidia -- Lock In. Sure, you may only have the cash to buy one card right now, but in a year when ATI releases their next new thing are you going to spend *another* $400 for the next new card, or are you going to buy the now "Budget" 6800 and get almost as good performance?

    It surprised me how painless the SLI setup process was described. Writting GPU drivers is complex enough without having to handle multiple accelerators, never mind having optimal performance AND making the install painless.

    nVidia does their homework with their drivers, and it shows. GPU drivers are 50% of their perfomance. It sucks for ATI, because they have the better hardware, but their drivers suck (and pretty much always did).

    I mean, come on, NONE and I mean NONE of my local computer stores have in stock ANY 6800GT (you have to preorder, takes quite a while to get it) or ANY 6800Ultra (don't think they *ever* had one in stock period) AGP. The only cards that seem to be fairly available are vanilla 6800s and even then they have been available for a month tops.

    Given that the GT/Ultra AGP cards have been announced *several months* ago, before their PCIe versions will be available likely NVidia will have already announced the 8xxxx series or something.

    I fondly remember being able to buy video cards max. 2 weeks after they were announced, then it was a month, then two, and now it seems cards become available together with the paper launch of the new models :(

    I really feel for the stores, though, it must suck being able to stock only 'previous generation' parts.
