I really only care about performance in a SIMD sense, as not using SIMD means you aren't targeting performance to begin with(GPU == SIMD, CPU SSE/AVX == SIMD)

I really only care about performance in a SIMD sense, as not using SIMD means you aren't targeting performance to begin with(GPU == SIMD, CPU SSE/AVX == SIMD) Branches fall off vs cmov/select as your lane count increases, they are still useful but only when you are certain the probability all lanes agreeing is reasonably high.
