Some people care only about maximum absolute performance, others care for performance per Watt. I find the latter much more sensible. What performance Apple can reach in, say, 50W, Intel reaches in 150W.

I have a list of instructions per clock from SPECINT results which I compiled from Web sources. (I didn’t verify the results myself.) I added in rumored future processors with their highest rumored performances:
