More profit on a 6950 than a 570gtx and if/when the 580gtx ever becomes properly available it will drop in price and face the same situation. AMD will sell several million more 6950's than Nvidia sell 580gtx's, it will be closer on 570gtx's, but again AMD makes more profit per card and WILL sell more £200 cards than Nvidia sell £250-270 cards.
AMD are sitting EXACTLY where they are before.
They haven't lost the performance/W lead, the 6950 beats the 570gtx in some situations, and uses, 80-100W less. If you benchmark Furmark with limits off, its closer, big whoop, in games, its not.
They lost the single gpu crown, they've not realistically had it before. The 4870 spanked the 280gtx in sales and gained mucho market share, and was slower the entire time, the 5870 was NEVER meant to beat a 480gtx.
They will not lose the dual gpu battle.
Number of mentions of a dual gpu card in Nvidia press........ none, number of mentions by Fud, loads, number of mentions of a dual gpu Fermi last year from Nvidia, none, mentions from Fud, loads, did it appear no.
Have AMD mentioned the 6990 in their slides, is it an official card we KNOW is coming, yes, is there a single piece of evidence Nvidia are bringing a dual gpu card that differs from the rumours last year, in source or believability, nope.
Will the 6990 cost less than current £450 580gtx's, probably similar, or close and it will be over 50% ahead. Nvidia, as per ever year for a LONG time won the single gpu card, how much difference has that made to AMD since the 4870.... none, its the strategy.
As for performance/w a single 6850/xfire cards beats any similar card in performance/w and in xfire beats the performance, signficantly, of any Nvidia solution, costs less, and has much higher performance/w.
Are you talking rubbish, as per usual..........
Edit:- uniengine is literally completely irrelevant at the moment, Metro is the/best realistically only even marginally decent game with tesselation, it barely uses it. It was irrelevant last gen, and irrelevant this gen, it might be relevant next gen if more than one "proper" tesselation game comes out.
Lets see, I said that when AMD sucked in uniengine, I'm saying it now they are fantastic in it.
A 389mm2 core should never, ever come as close as it has to beating a 520mm2 core, Nvidia have failed, significantly also, turn off power management in Furmark and you get VERY bad wattage numbers.
