Site with the WU graphs...

Semi-off topic, but I never saw why PPD/Ghz is used as a universal benchmark on these sites. Some types of CPU do more work per Ghz than others, others run at higher clock speeds to compensate. A chip with a higher PPD/Ghz is more efficient, but not necessarily better for Folding or anything else...

I think it's the only real way you can compare like for like - it's not much use for comparing completely different architectures.
By dividing the results by the clock speed you normalise them, ending up with many more results for a particular group of chips rather than focussing more on individual setups.

At least I think that's the idea anyway :p
