Benchmarks are meaningless. I know from experience at looking at the generated assembler code and intel Fortran's SIMD code that it's faster. Take a look at the generated code and then we can discuss it, but not before.

I'm not going to beat myself in C when I calculate a 100 million by 100 million matrix in Fortran. ifort will generate SIMD code with CPU autodetection and use machine code seqencing best for that processor, plus in Fortran a matrix is a normal variable type like any other. I'm not beating that with C (and I really know C).

And just so you know, my information isn't old, I come from supercomputing.
