When we tried the Compaq Visual Fortran 6.5 compiler, it built all SPECfp95 and SPECfp2000 benchmarks without a hitch. We achieved double digit performance improvements over other Fortran compilers. Compaq Visual Fortran 6.5 is, in our view, the best performing x86 compiler on the market. This chart illustrates the superior performance of Compaq Visual Fortran compared to other Windows Fortran compilers. The metric used is the geometric mean of the performance ratios for the specified number of tests from the SPECfp2000 industry-standard benchmark suite, compiled with the various compilers and run on the same system.
Higher scores are better.

Version 6.5 also includes the latest generation of Compaq's exclusive GEM optimization technology, along with other improvements, delivering superior application performance on all processor types.
