This of course has the subtle implication that it’s equally easy for x86 to go as wide as ARM, and it’s not.
Yes, it’s true that x86 often relaxes pitch, that doesn’t make up for a factor of 6 perf/watt difference like Anandtech measures.
Like I said, I guess we’ll see, Zen4 and A16 will be on the same node next year. By that time the goalpost will move to something else, like this “x86 isn’t designed for power efficiency” defense.
