compiler. All of these compile code that is as much as 70% faster than GNU in other-than-linpack benchmarks, & probably average 25-30 % faster.
That's not true on x86-64. The 64bit Integer code generated by gcc is still extremly competive with other available x86-64 compilers (e.g. as shown in SpecINT) For Floating Point intensive code there are some compilers who do better, but the differences are also not that dramatic. Of course you will always find some code that one compiler likes and the other doesn't, that is why in the end you should benchmark your own application yourself. -Andi
