NVIDIA GeForce 8800 GT: The Only Card That Matters

Line Substitution: 8800 GT vs. 8800 GTS
As we've mentioned, on paper the 8800 GT looks much better in every area except for memory bandwidth. Even though memory size is an advantage for the 640MB card, we know from experience that the added memory size really doesn't net us much in the way of performance except in the most extreme circumstances. So we certainly expect the 8800 GT to outperform both the more expensive 8800 GTS 320MB and (by extension) the 8800 GTS 640MB. Essentially, this should give us the performance of a $400 card for $200 - $250. Quite a good deal no matter how you slice it.
And from the first, our expectations are upheld and then some. The 8800 GT does top the GTS. This seals the deal: the 8800 GTS is no longer a viable product. While NVIDIA has stated that the 320MB part will be dropped very quickly, they expect the 640MB card to stick around for a few months. We don't see this happening unless retailers start selling the 640MB part for $250 as well. While such a drastic price reduction is possible, it isn't very likely. Once people hear about the performance difference of the 8800 GT over the 8800 GTS, there may be a lot of $400+ 8800 GTS inventory sitting on shelves.

What kind of G92 variants can we expect by Christmas 07?Or Summer 08?

ardOCP is reporting that nVidia is increasing the 8800GTS stream processors to 112.Spacecomber - Monday, October 29, 2007 - link

It appears that it was the bracketed h that was hiding all subsequent text. It needed a bracketed /h to close that "feature".mpc7488 - Monday, October 29, 2007 - link
Haha - thanks. I guess if anyone wants the explanation of the stream processors they can highlight the 'hidden message'.mpc7488 - Monday, October 29, 2007 - link
I'm not sure why the first post lost my text unless it was the bracket I used around the H - but HardOCP is reporting that nVidia is changing the 8800GTS 640 MB to have 112 stream processors.mpc7488 - Monday, October 29, 2007 - link
Great article Derek - I think you can tell you're mildly excited about this product :)Is there a reason that you didn't do any tests with anti-aliasing? I would assume that this would show more deviation between the 8800GTX and the 8800GT?

Nice job as usual Derek!Just wondering though, if you were able to test the cards at the same clock speeds. The GT by default has @100MHz advantage on the core over the GTS, which is a common reason the GTS falls so far behind in head to head testing. I expect the GT to have more OC'ing headroom than the GTS anyways, but it would be nice to see an apples to apples comparison to reveal the impact of some of the architecture changes from G80 to G92. Of note, the GT has fewer ROPs and a smaller memory bus but gains 1:1 address/filter units and 16 more stream processors.
Also, I saw an early review that showed massive performance gains when the shader processor was overclocked on the GT; much bigger gains than significant increases to the core/memory clocks. Similar testing with the GTS/GTX don't yield anywhere near that much performance gain when the shader core clock is bumped up.
Lastly, any idea when the G92 8800GTS refresh is going to be released? With a 640MB GTS this seems more of a lateral move to an 8800GT, although a refreshed GTS with 128SP and all the other enhancements of the G92 should undoubtedly be faster than the GTX...and maybe even the Ultra once overclocked.

I'm looking to build a HTPC and this would be a great card if it does video decoding?
