Many in the folding community have surmised that many of the new GPU3 work units seem to benefit cards with higher clock speeds rather than core amounts. We see this here with the 925 and 912 point WUs where the GTX 580 is able to maintain a sizable lead over the GTX 480 but when the cores start counting in the 611 pointers, the GF110 starts pulling ahead even more. At times, we saw a 45 second Time per Frame from the new card which is quite simply incredible.

We ran the Windows GPU2 client on the GeForce GTX 480 and the GTX 580 to see how the cards performed.
For our test we ran the 264 Fs_coil work unit on all of the pairs of cards and found that the GeForce GTX 580 was 12.7% faster per step than a GeForce GTX 480. When we overclocked the shaders of the card up to 1740MHz we were able to improve performance and the seconds per step dropped by five seconds! With this nice overclock on the 512 shaders we were able to get a 22% F@H performance improvement over a GeForce GTX 480 reference design! As you can see, the GeForce GTX 580 is faster, quieter and uses less power than a GeForce GTX 480.
