It's not clear that he's using "SMT" to refer to AMD specifically as he goes on to talk about "Intel CPUs" and disabling it in "Intel BIOS". Does the Zen architecture have the same issue?
SMT is the generic name? Hyper-Threading is the name of Intel's 2 way SMT implementation. I don't think they call the Xeon Phi 4-way SMT Hyper-Threading, but I could be wrong there.
