All else being equal, a complex decoding pipeline does reduce the efficiency of a processor. It’s likely not the most important aspect, but eventually there will be a point where it does become an issue once larger efficiency problems are addressed.
Well, not exactly. You have to remove instructions at some point. That’s what Intel’s x86-S is supposed to be. You lose some backwards compatibility but they’re chosen to have the least impact on most users.
