They got those kinds of numbers across multiple systems. You can take it up with them I guess.

I didn't even mention one of these systems was peaking at 59w on single-core workloads.

I see what's going on, they have two HX370 laptops:

  Laptop  MC score  Avg Power
     P16      1213      113 W
     S16       921       29 W
  M3 Pro      1059    (30 W?)

They don't have M3 Pro power numbers, but I assume it is somewhere around 30W, seems like S16 has similar power efficiency as HX 370 at 30 W.

Any more power, and the CPU is much less power efficient, 300% increase in power for 30% increase in performance.

This is true for every CPU. Past a certain point power consumption scales quadratically with performance.
