Unlike AMD and Qualcomm, Apple uses an expensive TSMC 3nm process, so you would expect better battery life from the "MBP3". I assume they used the process improvements to increase performance instead.

Perf per watt is higher for M1 on N5 vs Zen5 on N4P, so the problems go deeper than just process.

X Elite also beats AMD/Intel in perf/watt while being on the same N4P node as HX370.

Performance per watt also depends on clock speed. Other things equal, higher clock speed means worse performance per watt.
