AMD Cayman info (or rumor)

[Boissez]

So that's equivalent to some 2400 Cypress shaders for Cayman XT. With all the other improvements I'd say something in range of 40% faster than HD5870 is doable.

If these numbers are genuine it should be way above that. HD6870 is about 2 GFLOPS. So we're looking at around 50-60% over HD5870... and possibly a match for the 5970.
