Measuring 30b CPU speed reduction

This reduces the power consumption by a factor much greater than the ~5 time drop in CPU speed [...]

So, the correct car analogy is to say that driving a car at 20Mph DOES save gaz compared with driving it at 200Mph

This is math from a different universe. 200/5 = 40 or 100/5 = 20. Close to what Csaba got and hence my analogy was:

I meant no offense. Just didn't knew the underclocked CPU was more efficient.

Have I missed something?
