There's a more modern comparison here, comparing MS 2010, MinGW 4.6.1 and Intel 12.0: http://www.hardware.fr/articles/847-1/impact-compilateurs-architectures-cpu-x86-x64.html Intel generally wins due to their superior maths libraries anyway, but some of the AVX and SSE4 vectorizing ICC does is very impressive if you look at the resulting asm...
