PPD isn't the real benchmark on how fast a machine folds.
You'll see that the PS3 has turned in about 550 TFLOPS to date, while Windows machines have turned in about 186, and GPUs about 55. In termps of production per CPU, we get the following numbers: PS3 - 17.1 GFLOPS; Windows - 0.95 GFLOPS; GPU - 58.6 GFLOPS (based on active CPUs). Clearly, the GPU has the most power, nearly 3.5 times that of the PS3
True Chozart. Also keep in mind that the CPU number include CPUs like my P3 700mhz machines. So the CPU numbers are not realy apples to apples even when comparing current technology like a PS3 vs a new CPU.
