Um, you don't have to double EVERYTHING to get doubled performance. More than anything this depends on the particular application you're running, and where the bottlenecks lie within it.

If you look at a past example where performance WAS doubled, like the 8800GTX, let's compare that to the previous gen flagship, the 7900GTX. The 8800GTX had almost exactly twice the GFLOPs of the 7900GTX, even taking into account the nearly useless MUL op. The 8800GTX had 69% more memory bandwidth, and get this, only 33% more pixel fillrate, and 18% more bilinear texture fillrate.

The GF100 is more of an improvement in raw specs over the GTX 285 than the 8800GTX was over the 7900GTX. So doubling performance is more than possible.

Where in the post you're quoting I say that you have to double everything to double performance? I'm aswering a specific question.

And you can't compare G80 with previous generation, as it's a completely different architecture. Starting by the unified shader processors (instead of units that only could calculate vertex or pixel shaders), with a completely different architecture, and the same for TMUs and ROPs.

Again, I've never said that doubling is not possible (why is everybody putting that words in my mouth? It's at least the 3rd person who says that, and I'm starting to be tired or repeating it). You can read it yourself in my post quoted by Chumbucket843 (that I should add it's taken from a conversation including more posts before and after).

I have only said that there is not a single evidence which grants that the GT300 is going to be more than twice the performance of GT200.

But oh, well. If all of you are getting hurt by hearing it, I'll correct myself and let's finish with this: "GT300 is going to be obligatory at least 2x the performance of GTX285, and probably more". ¿Happy there?

EDIT: I have edited the former paragraphs to give a much more accurate response.
