Agree with most of the comment, just to point out (I could be misremembering) 4-wide SIMD ops that are close together often get pipelined "perfectly" onto the same vector unit that would be doing 8- or 16-wide SIMD, so the difference is often not as much as one would expect. (Still a speedup, though!) |
