Do Intel and AMD processor have the same assembler?
AMD and Intel processors(*) have a large set of instructions in common, so it is possible for a compiler or assembler to write binary code which runs “the same” on both. However, different processor families even from one manufacturer have their own sets of instructions, usually referred to as “extensions” or whatever. Ignoring the x87 … Read more

This means that the workaround no longer works, and AMD users have to either switch to OpenBLAS or keep using MKL.
