What, asking that a PPro 200 not be compared with a P166? He was
specifically talking about processers of the _SAME FAMILY_

So yes, comparing a P100 with a 486/100 is valid. It shows the P100
is faster. Comparing the MMX 166 with a P100 to show the "new" pentium
is faster is NOT valid.

Comparing CISC chips to RISC chips is always going to be diffuclt.

Tell me about it.. that's a great site. Good information for subtle
code tricks, as well.
