as i understand it, the regular PII, PIII and celeron chips will only
go to dual configurations. get a xeon if you need quad or more. the
ability to have more than two cpus is basically what xeon offers.
you'll notice nearly no one using them in uniprocessor and dual
machines.
xeon has faster cache than the pentia and more of it than the celeron.
since the speed rating difference is dramatic, i figure the higher
speed piii will beat the better cache size of xeon. cache is
important but it's a secondary issue. you'd have to benchmark to be
sure how important it is.
as the other poster stated, if you're doing number crunching then the
alpha ev6 will mop the floor with any of intel's offering.
also, depending on the task, it might be cheaper to get a bunch of
uniprocessor boxen. the athlon has bester performance than the
pentia.
