... Intel's C++ compiler, that cics uses, for instance, will take advantage of particular set of instructions, only if it's implemented exactly in the same way as in Intel's own CPU. Even then, I've read accusations that Intel-compiled code that utilizes SIMD demonstrates inferior performance on non-Intel CPUs (can't vouch whether it's true).
That's why for AMD processors, which support DIFFERENT set of instructions that they call SSE4a I believe, some other compiler would have to be used, for example GCC.
