You've seen it, you just needed a friendly reminder. Personally, I'm not listening to the slides from either company, but the specs match the percentages the slides are claiming. 1024 nvidia shaders (which are also reworked for kepler) with a 512bit memory bus is definitely enough to double the performance of the GTX580.

Either way, lets get back to the topic at hand here. AMD's 7xxx series.

But you are certain that GTX 680 or GTX 780 whatever it is called, will be over 2x faster than 580 at launch?. And btw 6800Ultra & 8800GTX were close to 2x faster at launch but they didn't quite make it that far. Please find evidence here and here. And please don't link things which shows it faster than 2x in under extreme circumstances and ideal scenarios. I'm talking in overalls here.

With each generation consuming more power and requiring more cooling, you can see why obtaining this yet again will be very hard with 28nm. Not to mention the normal diminishing returns, ie. even if you exactly double the GTX580 in every aspect, you will not get linear 100% improvement.

If you believe that then you are just buying into the hype too early...
