Just on the memory bandwith alone,it would go from 171GB/sec on the current GTX480 to about 205GB/sec,it would also get decent increases in raw shader math,more tesselation power,more raw fillrate and texturing speed would see a boost as well.
The trick is pulling the above while staying within the same power consumption limits and thermals of the current version,with better yeilds,and that might only be doable once the 40nm process matures some more and the physical layout of the chip is improved further still(IE new masks).
That would be very impressive if they could pull that one off. I would have thought only another revision would get that sort of performance increase though. That is if they do make a 485 and it is a new revision, rather than just a new model with more shaders and texture units unlocked.
