- Well in fact it is...but it's the most fair way to compare processors.
- There's little intelligence in comparing a 100MHz cpu with a 25MHz isn't it?

- Well it means cause if cpu A provides 2x power than cpu B at the same clock
- rate I tend to think that cpu A is clearly superior in terms of "power".

-
- Yes someone pointed that Intel has gained much in FP code.I was talking
- about 040 vs 486.However it seems that Pentium and 060 at same clock rate
- are about as fast.

-
- No this is wrong.Motorola tests say the 040 is twice as fast than a 486
- at the same clock rate.Pentium is instead just as fast than a 060 at the
- same clock rate.

-
- I'm not posting this crap..I've just stated that the problem is that Intel
- chips are available at higher clock rates.
