Well, the article is talking 65 and 80w, so uh, that's probably sadly not where these will end up.
There's a big gap between the 15w tdp on the steam deck and either of those numbers, especially in battery life (unless measuring battery life in minutes) and the fact that 80w in a steam deck would be less gaming console and more portable burn generator.
For laptops, though, yeah, that's looks pretty remarkable given that roughly equivalent laptops now use quite a lot more than 65w for that alleged performance.
