AMD Cayman info (or rumor)

[Mechanical Man]

Really ?? HD5870 has a 6-pin and an 8-pin but only 188W TDP.

The 6-pin and 8-pin show us the max power the card can draw from the PSU and not the TDP.

Did you forget about 6950?

My assumption, HD6870 2*6pin, just little under 150W. HD6950 2*6pin ~190W and 6970 8pin + 6pin ~230W.

50% more power than 6870, alteast 50% more performance than 6870, note also, that would put 6950 to 20-30% more performance than 6870.

1120/5 -> 224SP, 224/0,96*1,5*4 -> atleast 1400SP for Cayman XT for 50% more performance. 0,96 is modifier for 4 wide SP is less powerful than 5 wide SP. And we can assume it wont be smaller than Cypress was. So it is very feasible to assume atleast 50% more performance than 6870 even if 4 wide to 5 wide performance ratio is as low as 0,84 at same clock as 6870. Add to that larger core than cypress and little less clocks, say 850MHz. Still it will keep 50% more performance than 6870 very feasible.

So I will except no less than 50% more perfromance than 6870.
