For those unaware, this isn't AMDs top of the line laptop chip, but the top of the line ultra low power laptop chip.
It's meant for ~15W thin and light devices, not thick gaming laptops, AMD has 35W parts for those.

Notable improvements from previous generation:
* AV1 encoding
* AVX512 supportMany benchmarks for these 2 models can be seen at:

TLDR: Both Ryzen 9 7940HS and Ryzen 7 7840HS laptop CPUs (which are slower than the Ryzen HX laptop CPUs) are faster than the fastest 65 W desktop Intel Alder Lake CPU, Core i9-12900 (despite the fact that the latter not only uses more power, but it has 50% more threads).
And it's comparing against the previous generation 12900 instead of the current generation 13900.
And the extra threads on the 12900 are the E-cores, which aren't that fast.
Basically the result is that current gen AMD mobile CPUs are faster than last gen Intel desktop CPUs. Which is true, and not unimpressive, but far less informative than a comparison of like with like would have been.
