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

Prey Performance
With Prey being based off of the Doom 3 engine, only with some enhancements, scores tend to be quite a bit lower than many other games. At our maximum detail settings, dual graphics cards were previously required to play at the highest resolution. Now, a single 8800 GTX card is once again able to equal the performance of X1950 XTX CrossFire, which is no small achievement. The reduction in pixel and vertex processing power results in the 8800 GTS performing quite a bit lower, although it still manages to outperform 7950 GX2 by a small margin.
Quad SLI continues to be a disappointing prospect, providing no performance increase over a single GX2 card. The release of GeForce 8800 pretty much seals the fate of Quad SLI as well, as it's doubtful that NVIDIA will continue to invest time in optimizing the QSLI drivers when they have new GPUs that could make better use of optimizations. We can only hope that most of you didn't get sucked in by the marketing.

You must have missed the article they published the very next day http://www.theinquirer.net/default.aspx?article=35...">here. saying they goofed.Araemo - Thursday, November 9, 2006 - link
Yes I did - thanks.I wish they would have updated the original post to note the mistake, as it is still easily accessible via google. ;) (And the 'we goofed' post is only shown when you drill down for more results)

In all the AA comparison photos of the power lines, with the dome in the background - why does the dome look washed out in the G80 images? Is that a driver glitch? I'm only on page 12, so if you explain it after that.. well, I'll get it eventually.. ;) But is that just a driver glitch, or is it an IQ problem with the G80 implementation of AA?bobsmith1492 - Thursday, November 9, 2006 - link
Gamma-correcting AA sucks.Araemo - Thursday, November 9, 2006 - link
That glitch still exists whether or not gamma-correcting AA is enabled or disabled, so that isn't it.iwodo - Thursday, November 9, 2006 - link
I want to know if these power hungry monster have any power saving features?I mean what happen if i am using Windows only most of the time? Afterall CPU have much better power management when they are idle or doing little work. Will i have to pay extra electricity bill simply becoz i am a cascual gamer with a power - hungry/ ful GPU ?
Another question pop up my mind was with CUDA would it now be possible for thrid party to program a H.264 Decoder running on GPU? Sounds good to me:D

oh man ... I can't believe I didn't think about that ... video decoder would be very cool.Pirks - Friday, November 10, 2006 - link
decoder is not interesting, but the mpeg4 asp/avc ENCODER on the G80 GPU... man I can't imagine AVC or ASP encoding IN REAL TIME... wow, just wooowwwI'm holding my breath here

Great article. The only thing I would like to see in a follow up article is performance comparison in CAD/CAM applications (Solidworks, ProEngineer,...).BTW, how noisy are new cards in comparison to 7900GTX and others (in idle and under load)?
JarredWalton - Thursday, November 9, 2006 - link
I thought it was stated somewhere that they are as loud (or quiet if you prefer) as the 7900 GTX. So really not bad at all, considering the performance offered.
