To complicate things more HT performance varies wildly between CPU architectures and workloads. e.g. AMD implementation, especially in later Zen cores, is closer to a performance of a full thread than you'd see in Intel CPUs. Provided you are not memory bandwidth starved.

IBM's Power cpu's have also traditionally done a great job with SMT compared to Intel's implementation.

Whats the difference between Intels and AMDs approach?

		Basically it comes down to how much shared vs dedicated resources each core has.
