I was not able to find comparable results for all of these systems!
Apple officialy has posted only SPEC95 results. It is a pdf somewhere
on their web site.

probably (very likely) so. I'm in agreement here! :-)
Although, Athlons are very (VERY) reasonable and fast
for the most part I get Athlons to outperform PIII at the
same frequency doing int and fp stuff.
If moving big chunks of data then PIIIs are better.
