The most recent version, which added P-1 export to mprime, does not do stage2 at all anymore. The reason being that mprime (with some RAM) is so much more efficient at stage2 than gpuowl.

We ran the efficiency numbers for our new 6950XT.

The attached table shows the energy efficiency for this card. We have modified the fan curve to run at 1% fan speed per °C. (So if the card is 46 °C the fans run at 46%.) The PRP work unit we tested is in the 114.9M range. "HS" = GPU hot spot. Our "$/kWh" is roughly 10¢.
