Intel C/C++ compiler vs. GNU gcc/MS Visual Studio

the_real_tigga writes "OpenMag features a benchmark review of the Intel C/C++ compiler as opposed to gcc on linux and Microsoft Visual Studio compiler on Windows XP. Not surprisingly (for me at least), icc beats them both, with dramatic performance improvements. Too bad they chose to review gcc version 2.95, and not the 3.x series, which is known to produce faster code. What is surprising, even AMD CPUs benefit from the icc-compiled code. There is another version of the article here, and they provide a download of the used tools , so you can try it at home too!"
