Apple's perf/watt is much higher than AMD. Anandtech has the A14 within a few percent of the 5950X on single threaded workloads. Power consumption is 5 watts (entire iPhone 12) versus 49 watts (5950X package power).

Normalizing for performance (say A14 vs 5950X at 4.5GHz instead of 5GHz) would close the gap somewhat, but it's still huge. Perhaps 4x instead of 10x - those last 500MHz on the AMD chip cost a ton of power.

Of course, none of this is particularly surprising considering Apple is using both a newer process and gets nearly 60% higher IPC.

You are comparing a desktop processor that's been tuned to overboost as much as thermals will allow it to a mobile phone CPU ?!?

AMD has a laptop series of CPUs, M1 compared to that is the only relevant comparison - the rest is apples to oranges.
