Plausibly. But x265 maybe the most CPU stressful real software in the world, hitting the cores, caches, and SIMD super hard at once. Hopefully Intel is benchmarking x265 during development!

It is hard to predict the optimal performance tuning of a given CPU without actually having it, as theoretical improvements don’t always work as expected.

I’m curious if anyone has benchmarked performance improvements from arch-specific and profile-driven builds.

X265 is also pretty stressful for compilers too.
