Intel Compiler Compared To gcc

Posted by timothy on from the depends-what-you-want dept.

Screaming Lunatic writes "Here are some benchmarks comparing Intel's compiler and gcc on Linux. Gcc holds it own in a lot of cases. But Intel, not surprisingly, excels on their own hardware. With Intel offering a free (as in beer) non-commercial license for their compiler, how many people are using Intel's compiler on a regular basis?"

    I wasn't trying to imply anything that you are implying that I tried to imply. Intel writes an optimizing compiler. The compiler optimizes well for Intel hardware. I don't think that there are undocumented instructions or any other conspiracy theory. Intel would be stupid do that. It would give AMD more opportunity to whip them with programs compiled with msvc or gcc.

    I do believe that Intel engineers probably have a better understanding of branch prediction and cache misses on Intel hardware.

    I don't think these benchmarks give gcc a black eye at all. gcc aims to be a cross-platform compiler first, optimizing compiler second. icc aims to be an optimizing compiler first, cross-platform compiler second.

    And chill with the conspiracy theories.
