NVIDIA to Counter Radeon HD 6970 ''Cayman'' with GeForce GTX 580

[informal]

I'd wait and see for some official reviews there tiger before making that claim.

GTX480 is ~15% faster than 5870 today.Stream processor efficiency has been upped by quite a bit with NI generation(1120SP in BartsXT parts will almost be equal to 1600SP in Cypress-so lets say that "IPC" will go up by a decent 20%,not massive 42% as the SP count difference first shows).We will have ~1920SP with Cayman,each of which will be faster per clock than Evergreen class SP.Clock speeds are unknown for Cayman,but let's assume similar clock speed as 5870. On the conservative side,Cayman based 69xx will be ~45%(1.2 for the IPC x 1.2 for the SP count increase) faster than 5870.This alone is enough for it to crush any GF100 based single GPU card.
