AMD Cayman info (or rumor)

[Jowy Atreides]

So the 6870 seems maxed around 950ish same with the 6850 clocks high to 900ish, so what are they doing to this chip is it going to be the same size or are they adding things to it? I'm curious

Barts was a 5 shader part but tweaked if I'm reading the spec sheet correctly.
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
