> IMO, this is more on AMD than Intel. If Intel's kernel is faster than the open alternative, then Intel is doing AMD a favor, even if they're not doing the absolutely best job they possibly could.
If AMD chips are slow on the Intel-optimized kernel, then it's partly on AMD.
If Intel writes an "AMD-optimized" kernel that's worse on AMD than the "Intel-optimized" kernel, that's definitely not on AMD. And in that case it's not doing them a favor to make that kernel when they could just use the same code on everything.
