It seems Cayman will be the 4D shader reworked chip people were expecting.

Since Cayman has (currently rumoured) 1920 shaders vs Barts 1120 and they are beefed up as well, it would account for a greater performance difference than what you would expect on the same node.

IF the rumoured TDP of 300W is true for cayman and the 6870 is 150W max then it's likely that the clock speed of Cayman will be in the same sort of region.
Best case scenario is that it's almost twice the speed of the 6870.

Cayman also has a different tessellation solution and involves of chip loading of some sort.

I hope the 6970 is fast enough for 1920x1200 crysis at 60fps and it might just be plausible too that finally, a real crysis card exists
I really don't think 300W is plausible .... even the GTX480 was not at this level, and you have seen what was the reaction about it ... Why will you see AMD take the risk or have only the idea to release a single GPU card with 300W .......... don't feed the Fudzilla Fermi theory about Cayman ....
