Post Speed comparison for the above systems

I have given details and power consumption for my P4 and Celeron D systems above.

I here provide iteration speed benchmarks. From these you could work out electricity cost per iteration or electricity cost per exponent.

Time for iteration in ms (FFT size, my P4 left, my CeleronD right)

384K 11.893, 16.227
448K 14.217, 19.759
512K 16.250, 21.899
640K 19.439, 26.783
768K 23.719, 32.290
896K 28.028, 39.116
1024K 31.303, 42.686
1280K 40.896, 56.825
1536K 50.533, 69.411
1792K 59.986, 87.102
2048K 67.633. 97.131

The Celeron D isn't as fast but it's a cheaper system to build and uses less power.
