The gt 640 has zip to do with the slide I posted....
Third slide in the OP, man...
The slide I posted. As in me. Not the OP.
No, you are extrapolating performance with those undefined slides.
135% performance per core = 35% increase in SMX performance.
2x performance per watt = undefined. At what level? Shader? Core/SMX? ASIC? Architecture?
Sigh... nvidia is saying the numbers in plain English: 35% increase in performance per core is pretty plain, per cuda core. 2x performance per watt means, obviously, twice the performance per watt used of the GPU. You're reading way too deeply into it for things that they haven't said, nor I. Hence why I said "2.7x" per nvidia as a base factor. I would expect no less than double the performance of the 780, from the GTX 880 or whatever the Big Maxwell is, with these two factors known currently, and possibly more. Add in that this is first-gen Maxwell and GM200/204 will be "second generation" Maxwell, and things are looking rosy.
