I would say its about 10-15% on most games. You have 6% more shaders and then some refinements to z culling and FP16 texture processing. In theory assuming perfect scaling of the cores and perfect scaling of clock speeds you would need a 823
Mhz GTX480 to match a stock GTX580 (Memory speed seems to have little or no effect on performance). This ignores the fact that a GTX580 can also be overclocked quite heavily and has slightly better SLI scaling.
However, the architectural improvements in GF110 don't really warrant people to upgrade from the GF100 GPUs unless the temps or noise is a big issue (power draw is largely moot in real world scenarios).Edited by TickleMeElmo - 1/30/11 at 12:22am
