just curious why you think Power is so amazing.
to me, it's impressive the engineering that IBM can still bring to bear, but the results are distinctly meh. sure, they occasionally get out in front in some micro-architectural metric. but differences that matter to real systems?
the only thing I can think of is Power's tight integration with Nvidia - really just a political thing. And who cares much about it? It is at best a marginal benefit for a very niche market (gold-plated HPC clusters).
real SMT, sure, but show me a widespread use-case where that's critical.
