Intel Fortran vs gcc ???

How about Intel Fortran vs. Intel C ? How about gcc C vs. gcc Fortran ?

Hyper-optimized compiler for Intel architecture beats compiler designed to be portable to many, many target architectures? Not very shocking.

This. ICC is known to beat gcc usually.

Yeah, I'd suspect that better use of SSE instructions is the big win for number crunching.

Cool. Yeah, seems like it's better inlining and use of XMM registers more than the SSE instructions themselves.
