Just grab a beefy x86 CPU (e.g. one based on AMD zen4) and put it in SMT=1, and you'll probably have a much better experience. A lot of windows/Linux software is already optimized for x86, and you'll get good performance uplift per logical thread from SMT=1.

Is this true? You mean this implies single threaded applications will perform better?

If you're referring to the SMT=1 part it means not more than 1 hardware threads will be assigned to a hardware core at a time, not that the processes are single thread.

If you're referring to the general performance of single thread apps between the two yes.
