Despite the implication that this is pointless, I looked at a really small 1260P based system last year as a lightweight work travel machine that could also do gaming. It could, but only for older titles. I ended up spending more money for a larger and heavier device because it just missed my performance targets for a couple games i wanted to play.
This overclocking, along with the already stronger generational improvements over the intel 1260P, means that a lot of the games that would only hit 20fps at 1080 are now a playable 30fps. This isn't 'pointless'.
FF14, for example, was borderline before. This makes it a decent experience.
These little incremental gains shouldn't be undervalued, as each of these incremental gains is putting another class of games within reach of these ridiculously small thin and light and cheap laptops. And it applies to the Intel parts as well, not just AMD.
The steamdeck APU, for example, is 'only' 1.6TF at peak power (most of us run it much slower it for better battery and have it at 1TF.), and no one scoffs at that chip. These thin and lights are getting closer and closer to steamdeck performance here.
