AMD Cayman info (or rumor)

And if it doesn't, 580 will spank you

nope my 5970 is safe a single 580 does nothing for me, two 580s are the other hand are a little dangerous If the 580 was $350 then they would be worth it.

i would have loved to see a 2400sp monster with a 250W+ tdp...
but then again, it probably would have been very expensive and going dualgpu wouldnt really have made sense anymore...
i mean think about it, if your in the same tdp envelope as a dual gpu card almost, then theres not gonna be a big perf boost by going dualgpu, so then you pretty much kill the dualgpu option... since ati continues to rely on dual gpu, that caps their highest single gpu cards to be around 200W, and again more than 2000sps would have meant way low clocks and wouldnt have been much faster than 2000sps...

2000 sps sounds a bout right for 400mm2, thats a 25% boost, then add a 15% ipc boost, which i think is generous, and you got a 40% boost over a 5870, which puts it in 580 territory. might beat it, but not notably...

and after all, justifying a 580 is already hard to do with the lack of nice dx11 games out there...
so a monster cayman wouldnt really have been useful would it?

Have you seen the benchmarks for metro 2033 or BF2:BC? I guess you don't game at 2560x1600, it takes two 580s to make certain DX11 games playable in single player. This reminds me of 3DFX saying 30fps is fast enough At stock The 5870 can do 212watts of power and the 4890 does 227 watts of power, so the 6970 doing 250 watts of power is not that hard to believe. Why else would they be coming out with a way to tune the power draw of the card? Why is is so hard to believe that some things are possible?


edit: I'm not referring to the sps just total power draw. I'm not sure what cayman's efficiency will be like yet, but I do believe it will be much better than the weak 6870.
