Very cool comparison, thanks a lot!

I think gcc has a lot of knowledge and experience under its belt, a larger
user base so no wonder it performs [slightly] worse. What has really
surprised me has been ImageMagick, apparently because of openmp. The OpenMP
stack has been contributed by intel, clang 3.4 if I recall it right.
Surprising.

Cheers,
Fernando
