"Because GT200 doesn't implement a brand new architecture or change possible image quality compared to G80 or G92, we've been able to skip discussion of large parts of the chip simply because they're unchanged. There's nothing new to talk about in terms of maximum per-pixel IQ, because the crucial components of the chip that make that all happen have no improvements or changes to speak of. It's purely a question of performance and how that's derived."
As the R&D budgets for new GPUs continues to increase, nVidia and AMD are going to have to offset those increased costs by selling cards for more purposes than gaming. This is especially true since now GPUs like GT200 and RV770 have so much processing power. And GPGPU will become even more important in the face of Intel's Larrabee, which is going to be more general purpose and more suited toward such applications than current GPUs from nVidia and AMD.
It seems that nVidia took a page out of ATI's book with GT200, and they prioritized the shader core over the rest of the chip. GT200 has 87.5% more stream processors than G80 while it has only 25% more texture units and 33% more ROPs. The ratio of SP : Tex has increased from 2:1 in G80 to 3:1 in GT200. If we had more texture power in GT200, we would likely see more performance.
The other reason GT200 isn't such a monster is clocks.... the shader clock on the GTX 280 is lower than on the original 8800GTX, and the core/shader are much lower than on the 8800 Ultra and 9800GTX.
To be honest I'm wondering why GT200 has so many transistors..... no where in the chip do we see 2x G80, yet we see over 2x G80 in the number of transistors. Where are all these transistors going?
And about increases in gaming performance, AMD will certainly be providing that with R700.
