Rumors of 4-way SMT on Zen 3 are making the rounds, parallelism not yet seen with x86-64. I have questions.

1) what sort of changes (from Zen 2) might AMD need to make in order to see an increase in performance of multi-threaded workloads?
2) is there likely to be a performance uplift in any desktop workloads?
