Nvidia confirms GT-200 with 1 billion transistors

R600's formula didn't work because it couldn't USE the bandwidth. Too few rops, inefficient AA, too few tmus for AF... The rest of the architecture held it back.

Also, you realize you'd need roughly 4ghz GDDR5 at 256bit to match 2ghz GDDR3 at 512bit, right? Also, GDDR3 is likely to be lower latency than GDDR5 as well.

I think his point is that if the two options can provide the same bandwidth (256+GDDR5 vs 512+GDDR3) it's cheaper and way less complex to design and use the first. And I agree with that. I loved the R600 PCB's visual, but looking at it from a practical POV, 256+GDDR5 is better. Also, 512bits will force NVIDIA to use 16 chips in one PCB, just like the 2900XT. If they plan to do a GX2 with the GT-200, I just can't imagine the monster PCB (two of them more than likely) it'll be with 32 GDDR ICs, that huge chip and all the power circuitry.

Of couse it'll be fast, but I don't want a second 2900XT talking about heat and power consumption.
