But even the M1 isn't an order of magnitude ahead on power/performance ratio. It's the leader, but it's sure as shit not 10x faster for the same power draw.
Android phones with Qualcom Snapdragon 865 scores better than an Intel i7 7700HQ (4 cores, 8 threads) on Geekbench on multi-core and ties on single core while using a magnitude less energy.
While this i7 model is not new, it's not the "U" low voltage processor version.
I could see Qualcom getting fancy and trying to scale their processors at 5nm.

Single core performance is ~17.5% better and multi-core performance is ~51.2% better than the 865. The numbers are still surprisingly close given that the Snapdragon uses significantly less power.

Or the 15w Ryzen 4800U's results https://browser.geekbench.com/v5/cpu/4972763
Shows how poor is Intel's form lately.
