If I remember correctly, benchmarks of the ryzen 6800u (not quite this chip, but close) showed that the perf/watt sweet spot was probably _less_ than 15W. Even at 28W there were clear signs of diminishing returns, and anything north of 50W is largely pointless.

The intel competition in the form of alder lake scales for much longer if you just pump more juice into it. Scaling varies from chip to chip.

Edit - I might be misremembering, because 6900HS's sweet spot was at 20W: https://www.anandtech.com/show/17276/amd-ryzen-9-6900hs-remb... But anyhow, they also noted that "going from 50 W to 80 W is a 60% power increase for only +375 MHz and only +7.7% increased score in the benchmark".

But TL;DR: 15-28W probably really is the ideal range for a chip like this. Which won't stop ODMs from pushing well beyond that, of course.
