AMD Cayman info (or rumor)

I really hope those numbers are accurate.

From 1120 5d in barts to 1920 4d vliw tweaked in cayman alone is a 71% increase.
Factor in the ipc improvement, the much larger framebuffer, the new offload tesselation engine and you have a very feasible 80% bump in speed.

Edit: Don't forget the clockspeed being 860Mhz compared to the 725Mhz of Barts xt.

Think about the logical evidence of the architectural changes shown above and you'll most likely conclude like myself, that the 580 is NOT going to be serious competition.
