Actually, I wasn't asking which one was better though :) I'm only curious
as to how I can compare the two ... its kinda like Sun vs Intel ... I know
that the Sun should usually outperform Intel on fp, but Intel tends to do
a pretty good job against Sun on int operations ...
I'd tend to agree, and Kenneth also, it seems-- the raw FP performance of the P4s is kinda pokey compared to their int performance. But whether that matters depends on what tasks you're doing.
...although the spec2000fp numbers are 641 vs. 726, so the Xeon does
better at floating point. For that particular test, anyway. Do you
require SMP capabilities? What are you trying to do with this machine?
Server environment, Dual Processor ... web/mail/ftp generally ... all our
current servers are Intel based, but looking at the costs, the AMD are so
much cheaper, just figured for next one I'd check out what AMD had to
offer as comparable ...
Just trying to do some comparison shopping ... :)
OK. The price difference for AMD vs. Intel is pretty significant, but be aware that you'll also pay a significant premium for dual-proc hardware versus single-proc machines: compare an AMD 2400MP versus the 2400XP price, or the 2.4GHz Xeon P4 vs. a Northwood P4, and then factor in the additional costs for a MP-capable motherboard.
Are your machines especially busy, ie CPU-bound? Two 2.4GHz processors is a lot of computing horsepower, although dynamic web content generation or virus scanning can be resource intensive if there's enough traffic...
