Why are you comparing it to GHz though RS, why not 780 vs Titan in OpenCL?
I provided GTX780 vs. Titan, GTX780 vs. HD7970 and a general graph with many cards.

What's the problem again balla? I clearly noted that compute performance looks significantly lower vs. the Titan compared to the specs of the 780. That seems odd to me unless the card was neutered in compute.
-now that nv is going 2 high end chip sizes 20 nm will be the same. amd can not compete with nv pro chips waiting to sand bag them at every node.
-had they completed their refresh ,even if they matched titan , nv would have unlocked the clocks so still no win for amd .
-unless they go for a big chip [10% smaller than titan like chips] and cripple anything under a titan like chip for nv , but can they do that with out deep margin cuts or a loss .,
Pretty much. Ever since NV went to a large die strategy starting with G80, it was nearly a foregone conclusion that unless AMD makes large die chips (500-550mm2) chips or miraculously invents a far more efficient architecture (9700Pro) or NV makes a very poor architecture (GF5), then NV will continue to hold the performance leadership indefinitely.
I don't know why this is a surprise to people. AMD cannot afford to make 550-560mm2 chips since the costs of R&D and manufacturing of such large chips wouldn't make them profitable as gaming chips. It's different for NV because they amortize those costs across Tesla/Quadro and are making a killing on those product lines.
The biggest difference this generation is NV raised the price far beyond 8800GTX, GTX280/480/580 levels. If you go back as far as 2006, NV has maintained the performance crown, except from late June 2012 to the Titan's release when HD7970GE was faster than the 680. Going forward, NV has tested the $1000 price level with GTX690/Titan. I do not see why this won't become the new pricing point for NV's 550mm2 chips as the market seems to be paying. If VI is 460-480mm2, then maybe it can come within 15-20% of the flagship Maxwell card. Will AMD price a 460-480mm2 chip at $549 though? If GTX780 is $649-699.
They want to sell and make money, not have the performance crown. They're more than willing to give up a performance crown if it means they make money.
I am pretty sure AMD wants the performance crown but based on how NV and AMD run, at the current time AMD cannot afford to make 550-560mm2 die gaming cards. It's not justifiable from a financial standpoint given their small market penetration with FirePro/computing solutions compared to NV.
