The answer we’ve decided is one of mild, but well earned praise. The GTX 580 is not the true next-generation successor to the GTX 480; it’s the GTX 480 having gone back in the womb for 7 months of development. Much like AMD, NVIDIA faced a situation where they were going to do a new product without a die shrink, and had limited options as a result. NVIDIA chose wisely, and came back with a card that is both decently faster and a refined GTX 480 at the same time.

Full Fermi with optimizations.
480 is a
lot faster than a 285, close to twice as fast at times, and a 580 actually increases that gap by quite a bit (2 to 2.5 times as fast).
I must admit 580 is a more substantial improvement than I first figured. Typically you'll see 10-15% improvement, but it can go as high as 20-25% more fps, depending on the application and the quality settings (bigger difference at higher qualities).
*Also; GTX 570:

Whereas the GTX 580 took a two-tiered approach on raising the bar on GPU performance while simultaneously reducing power consumption, the GeForce GTX 570 takes a much more single-tracked approach. It is for all intents and purposes the new GTX 480, offering gaming performance virtually identical to the GTX 480 at a lower price, and with less power consumption along with lower temperatures and less noise. As a lower tier GF110 card the GTX 570 won’t wow the world with its performance, but like the GTX 580 it’s a solid step forward. In this case it’s a solid step towards bringing yesterday’s performance to the market at a lower price and with power/thermal/noise characteristics better suited for more systems. If nothing else, NVIDIA has translated the GTX 580’s excellent balance of performance and noise to a lower priced, lower performing tier.
