My System Specs


It's not a PPD/Watt issue. It's an underutilization issue. Nvidia cards are typically close to 100% utilized when folding. My 7950 is always less than 50% utilized. The folding platform just doesn't seem to fully utilize AMD Cards. However, the power used by my card is correspondingly low. I'd be surprised if it uses more than 100W of power.

The thing is, when folding with my 7950, it halves production on my CPU (about 15K when not GPU folding). So, when I only have my 7950, it doesn't make any sense to GPU fold, as I have a net decrease compared to SMP-only.

CPU (smp-only) - ~15K

CPU (smp while GPU folding) ~5K
7950 - 5K
GTX295 - 14K

as you can see, while smp folding only, I get 15K. While folding with only my 7950, I get about 10K PPD. But add in the 295, and I should start to get an average of 20-25K ppd.

Eventually, the GTX295 will go into another rig (powered by an A6 APU which won't be doing -smp), and I'll fold only smp on my main rig. That combination should hopefully net me about 28-32K PPD. I'm also planning on buying a used GTX550 to throw into my HTPC solely for the purposes of folding - purportedly good for another 12K.

HTPC: Z77A-G45; 3770K; Zalman FX70; 2x4GB Kingston HyperX 1600Mhz; MSI GTX960; 2x 128GB Crucial M4 SSD; 4TB WD Red, 2x 2TB WD Green; Corsair RM650I; Corsair Carbide 600C;
Son's Rig: M5A97; FX8350; CNPS20LQ; 2x4GB Corsair Vengeance 1600Mhz; Powercolor 7950; 250GB Crucial MX200; 320GB WD Black HDD; SPI 700W; Bitfenix Shinobi;
