  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.
