FYI, this was linked from Slashdot:

It's a fairly detailed performance comparison of GCC-generaged vs.
Intel C++-generated code, using a bunch of different benchmarks.
The most interesting comparison is the Monte Carlo integration in
Scimark 2.0. The code from Intel C++ is almost 3x faster on the
Pentium III and almost 5x faster on the Pentium 4. On most other
benchmarks, the Intel compiler's code is a little bit faster, not
enough to get too worked up about.
