Pitcairn is the most efficient GPU this gen, and that belongs to AMD.
Oh absolutely, GPGPU performance of Kepler is nerfed beyond belief.
But its not really a valid argument if we are talking about game benchmarking, which is what 99% of us use to compare one card to the next. The reality is that Nvidia managed to get their planned mid-range card to perform at the same level of the best card their competition has on offer.
I know a lot of people don't like that Nvidia did that. But at the end of the day, if Nvidia released GK110 now as the GTX680 and beat the 7970 by say 30% on average, they would be shooting themselves in the foot. Why would you sell a card that performs the same as a $550 card for a mid-range price tag? You wouldn't. It doesn't make any business sense. What does make business sense however, is what Nvidia are doing, they are holding off their big guns until a time in which AMD has something on offer that competes with it. Atm, from the rumored GK110 performance, it would be fair to say we could see anywhere from a 15%-50% increase over a 680/7970. Now why would you release a card that's lets say 30% faster (for arguments sake) than the competition if you dont have too? Because all that will do is de-value the other cards in the line up, in turn, eating into profits. And they are a business after all and we would love to see the GK110 card as consumers, but ultimately, from a business perspective, Nvidia are playing it smart.Edited by Vengeance47 - 5/3/12 at 11:20pm
