Agree with most of the stuff below, but there is one difference between
the Intel and AMD chips you might find important. We put a fair amount
of effort into the Pentium 4 to have it self-monitor its temp. If it gets
too hot, the processor throttles its own performance until it has cooled
down. The idea is that if a fan fails, or the cooling vents are blocked,
it's better for the machine to keep running than to take a chance on the
CPU becoming permanently damaged. Reading Tom's HW page, I get the distinct
impression AMD did not provide this same facility.

Yeah, well my point is not that you can find a pentium that is cooler
than an athlon if you compare certain models of chips across particular
generations of manufacturing -- it's that blanket statements like
"athlons are hotter than pentiums" aren't true.
When *I* bought my CPU, there weren't any 0.13 chips, and the AthlonXP
was genuinely cooler than the P4! Intel has moved to a new process that
gives them better power specs, but soon enough AMD will do the same and
then their chips will be cooler instead, and then the cycle will repeat
again...
