In Cinebench 2024, Vivobook S15(X Elite 78-100) scores 108 and consumes 14.4W of power. Macbook Air 15(M3) scores 142 and consumes 9.98W of power.
But notebookcheck measures device TDP so idle must be subtracted from these figures.
Idle power for the Vivobook is 4.4W and 2.15W for the Macbook. Subtracting these figures, we arrive at 10W CPU only package power for the Vivobook and 7.83W CPU only package power for the Macbook.
The M3 Macbook pro is 31% faster than the X E while consuming 20% lesser power than the X Elite.
This gives the M3 P core a 61.7% better P/W advantage over the X Elite. Bear in mind this would increase if we compare them at iso performance.
