It's not just the math libraries (although these are indeed much better - especially under Linux), its loop unrolling and vectorization using intrinsics are much better than other compilers in my experience.
However, no compiler I've found can get close to hand-crafted intrinsics in non-trivial cases.
- justincormack 15y agoThat may well still be so, but these benchmarks did not seem to pick that up, I dont think any of the code was significantly vectorizable anyway....
