NVIDIA's GeForce 8800 (G80): GPUs Re-architected for DirectX 10

We're going to dispense with a lot of the introductory commentary for all of our gaming benchmarks, as we already have a ton of material to present. At this point, most of you are already familiar with what benchmarks we use and how they are run. If not, you should easily be able to find the information in a previous article. So, rather than adding hundreds of words of repeat text, we're just going to cut straight to the chase and talk about performance.
Company of Heroes Performance
Starting with Company of Heroes, we have a game that really stresses the graphics card at higher settings, though in the past we've also shown that it tends to be CPU limited with different detail settings. Running maximum details, all of the cards still managed to deliver acceptable gameplay at 1600x1200 or lower resolutions. 1920x1440 is still playable as well, but if you have a 30 inch LCD running 2560x1600 and you want to run with antialiasing, you're really going to need a GeForce 8800 series card. The GeForce 8800 is clearly more powerful than anything ATI currently offers, which is to be expected as it's a next-generation card competing with current generation hardware. What's impressive is that the 8800 GTX is basically as fast running 2560x1600 as the GeForce 7900 GTX or Radeon X1950 XTX running at 1600x1200. Put another way, a single 8800 GTX is over twice as fast as a single X1950 XTX in all of the tested resolutions, and it's also about twice as fast as a 7900 GTX.
As far as multiple graphics card configurations go, Company of Heroes currently did not show any performance improvements. Most likely that means that NVIDIA and ATI drivers have not been properly optimized for this game at present. This is a problem that occurs periodically with new titles, and it's always frustrating to get a new game only to find out that it isn't properly using your hardware -- especially if you've shelled out the money for dual graphics cards. This is why we have repeatedly recommended in the past that you purchase a faster single graphics card rather than moving to dual GPUs, up to the point where you basically have the fastest single graphics card available. GeForce 8800 GTX now holds the title of fastest single GPU, so if you were previously looking to spend $800 on a couple of GPUs, you should seriously consider a single 8800 GTX instead. The DirectX 10 support is merely icing on the cake.

You can just use the program DX Tweaker to enable Triple Buffering in any D3D game and use your VSYNC with negligable performance impact. So you can play with your VSYNC, a high-res and AA as well. :)aweigh - Friday, November 10, 2006 - link
I'm gonna buy an 88 specifically to use 4x4 SuperSampling in games. Why bother with MSAA with a card like that?DerekWilson - Friday, November 10, 2006 - link
Supersampling can make textures blurry -- especially very detailed textures.And the impact will be much greater with the use of longer more detailed pixel shaders (as the shaders must be evaluated at every sub-pixel in supersample).
I think transparency / adaptive AA are enough.
On your previous comment, I don't think we're to the point where we can hit triple buffering, vsync, high levels of AA AND high resolution (2560x1600) without some input lag (triple buffering plus vsync with framerates less than your refresh rate can cause problems).
If you're talking about enabling all these options on a lower resolution lcd panel, then I can definitely see that as a good use of the hardware. And it might be interesting to look at more numbers with these type of options enabled.
Thanks for the suggestion.

I never knew that about SuperSampling. Is it something similar to Quincux blurring? And would using a negative LOD via RivaTuner/nHancer counteract the effect?How about NVIDIA's Digital Sharpness setting in Color Correction? I've found a smidge of sharpening can do wonders to improve overall clarity.
By the way, when you said Adaptive AA, were you referring to ATI cards?

Derek,Saw your comment regarding the rationale for the test resolution, while I understand your reasoning now, it still begs the question how many of your readers have 30" LCD flat panels?

There might not be many out there right now, but it's still the right test platform for G80. We did test down to 1600x1200, so people do have information if they need it.But it speaks to who should own an 8800 GTX right now. It doesn't make sense to spend that much money on a part if you aren't going to get anything out of it with your 1280x1024 panel.
Owners of a 2560x1600 panel will want an 8800 GTX. Owners of an 8800 GTX will want a 2560x1600 panel. Smooth framerates with the ability to enable 4xAA in every game that allowed it is reason enough. People without a 2560x1600 panel should probably wait until prices come down on the 8800 GTX or until games that are able to push the 8800 GTX harder to buy the card.

Derek,A follow up to testing resolutions, the FPS numbers we see in your articles, are they maximum, minimum or average?

Who the heck runs 2560x1600? At 4XAA? Come on guys, real world benchmarks please!DerekWilson - Friday, November 10, 2006 - link
we did:1600x1200, 1920x1440, and even 1280x1024 in Oblivion
