> with Haswells mediocre improvements Intel has really not come up with anything substantial in years Unlocking Haswell's performance (up to 2x integer/FPU) requires using AVX2 instructions. Which means at least recompiling and to truly extract the performance, optimizing to AVX2 intrinsics or assembler.
