It does AVX2 at half speed, AVX1 at full speed, but in return it runs at full clock rates with AVX, so it's not as bad as it sounds.

- emn13 9y agoMost programming related workloads I can think of hardly benefit from avx2. Also, the additional power draw while using avx on intel is considerable, despite the clock rate drop; so perf/watt may not be as much behind as one might initially think. This downside is likely to become slightly more serious as time goes on and more software uses avx2; but it's certainly not crippling.
