> You can't expect intel to benchmark if a feature would be better or not on amd, that's not its role. It is, in facts, its role as a major contributor. And they do, in fact, benchmark and fix AMD as part of its open source efforts, as they should. Case in point: https://github.com/OpenVisualCloud/SVT-VP9/pull/48 https://github.com/OpenVisualCloud/SVT-VP9/pull/48 (Intel developer contributing AVX2 improvements, specifically mentioned as AMD Epyc improvements). They can cater only to their own devices when the code only applies to those devices (e.g. the i915 graphics driver). In generic code paths, they must cater to all users. Adding optimization using generic features that have generic flags, but hiding them behind vendor detection, is borderline malicious. The developers here are well aware that there is a feature flag they should check instead.
