wikipedia still says intel compiler make slower code for amd:
"The compilers generate optimized code for IA-32
<http://en.wikipedia.org/wiki/IA-32> and Intel 64
<http://en.wikipedia.org/wiki/Intel_64> architectures, but non-optimized
code on non-Intel but compatible processors, such as certain AMD
<http://en.wikipedia.org/wiki/Advanced_Micro_Devices> processors. A
specific release of the compiler (11.1) is available for development of
Linux-based applications for IA-64 (Itanium
<http://en.wikipedia.org/wiki/Itanium> 2) processors" --
But then, 2008 tests by some random programmers say patched icc is still
better than gcc
