Acronym/initialism definer here. There are two in your comment that I wasn't familiar with, although I understood them once I saw them spelled out.

SMT is simultaneous multithreading, which may be more familiar under Intel's name of hyper-threading.

PPA is not the Professional Photographers of America, nor the Professional Pickleball Association, nor the Philadelphia Parking Authority, all of which came up at the top of my naïve search.

It's Power-Performance-Area.
