I don't really get your post. I never said that I want to 'beat' the performance of x86 Fortran. This particular framework is designed to make Fortran GPGPU compatible while not loosing any CPU performance. It was used to speed up the next generation Japanese weather physics by 3.5x (compared to six core Westmere) doing exactly that.
