i have some povray benchmarks. they're much faster than my old celeron 800.
they even beat my dad's celeron 2ghz by 33%. what i find interesting is
that the gcc compiled binaries beat the icc binaries. it was vice versa on
my old celeron. in a nutshell, gcc (3.2.x) is better than icc (7.x) for
povray on an athlon-xp core cpu

I think there is something wrong on your dad's pc : a celeron 4 @ 2GHz 
CANNOT be slower than a celeron 2 @ 800 MHz !!!!

On an other hand, you must not compare ICC and GCC on a non-INTEL 
processor : INTEL has no reason to create optimized compiler for 
concurrent processors !

Finally, GCC and ICC have been largely improved since you got your old 
celereon

  You are somewhat prejudiced.

  It is well known that optimizing for P4 gives speed advantages also
in AMD processors. The P4-optimized binary might not be the fastest
possible binary which could be compiled for the AMD, but it's clearly
faster than a P3-optimized binary.

  I believe it's not like Intel has no reason to optimize for AMD; it's
like Intel doesn't really care, but their optimizations just happen to
give benefits when run on an AMD as well.

  Thus it's quite fair to compare icc and gcc on an AMD system. The gcc
binaries might usually win, but I think often the icc binaries give a
quite good challenge.

	Let's start spreading a little teaser:

	You have to be more specific than that so anybody can
really grasp the meaning of your numbers.

	Both are outdated compilers and do not reflect the current
state of nowadays compiler performance.

	I'd suggest you first start by presenting your results
with graphics (if you can post that on some website) and wrap
them with more explanatory text.

i was actually referring to my duron 1.6 being faster than both. i'd like to
do a gcc 3.3/3.4 vs. icc 8.x but i don't really have much time now. and by
the time i do get around to it, there will probably more compiler upgrades.
