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

[tajoh111]

It looks like the card is real and we might get a performance preview in november.

It sounds like the gtx 580 is real, if charlie is saying it is(if the most pessimistic hating guy is saying), I think at the very least the card has to exist.

The plan is simple, in November when DAAMIT launches Cayman, the top single chip Northern Islands family, Nvidia will 'launch' the GTX580 as a 'spoiler'. Tame sites will tout the wonderfullness of this paper part, and a few loyal Nvidia 'partner sites' may even get a card.

Cards will actually be available in late January.

Atleast we are getting performance early this round rather than waiting another six months for that.

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.

How much does this go down if barts xt proves just a little bit faster than a 5850? The only thing I can see bart xt outperforming a 5870 is in directx 11. It impressive enough if they can get 5850 performance out of a die that is 33% smaller.
