It was already opt-in (disabled unless you also disable efficiency cores), that is no justification to make it impossible to use for people who want to try it out.
But I suppose Intel just doesn't want people to write software using those new instructions.
- fomine3 4y agoIf Intel allow to enable AVX-512, they need to validate functionality on every chip. Some chips may dropped (or reused as i3) due to this. There's not much reason to do so for AVX-512 that only enthusiasts enable.
