Right. Because AMD had the same instructions (but presumably different pipeline timings?), they kept their secrets behind a bit of a wall which added friction for people who would have liked extra performance but not been willing to jump through the hoops required to get it. So now Intel chips are limiting battery life because every application is executing unoptimized garbage that runs longer and therefore uses more energy. Meanwhile, Apple Xcode will produce optimized binaries for Apple Silicon and the press will go wild.
