I took the first review (the most popular) and at 1080p you can clearly see the 7950x 3d is not the fastest in all games. Depending on the games you choose yes AMD win overall, but not in everything, and not in the 1% lows which as AMD fans know fine well is a big deal, or it was.
To simplify it, the 7950x 3d is not the fastest in enough of the games I’ve seen tested to be the outright winner. And certainly not by as large a gap as people in here try to make out.
Power efficiency under load yes 100%. But not at idle
