Spike, you'll have to come up with a better explanation than that.
I think for us hardcore computer types its generally agreed that
the P4 is a lemon. Until Intel starts producing it on their
next smaller fab and ups the processor speed to 2-3 GHz it really
isn't as great as Intel would like you to believe. It was designed
to be a deeply pipelined processor that could run at very high clock
speeds (and heat your house in the process). Until it is operating in
the range it was designed for its a door stop as far as I'm concerned.

The only "caveat" is if there is something in the deep pipeline
architecture that prime searching can take advantage of. But
if not and especially if there is any floating point involved
my impression is that the Athlon kicks the P4's butt at least
at this point in time.
