Normally, when someone creates a benchmark to show off their system, they choose the compiler that will make their product look the very best. With judicious choice of compiler flags and PGO, the latest GCC compiler can often perform about as well as the Intel compiler. If they chose GCC, it is probably because GCC produces a better binary than anything else at their disposal. And if that is the case, then we are certainly seeing the true measure of performance. After all, anyone else who creates software tools will have to use that compiler or an inferior one also. Do you think that INTEL is going to target the MAC with a version of their compiler? ;-)
