I think it does also help that a big chunk of Steams userbase are playing smaller indie titles that don't need obscene amounts of vram. The steam deck audience for example has a lot of people playing both a mix of AAA and smaller games. Given this is advertised as 6x as powerful as the deck I'm sure they'll be fine. It's not meant to be a top of the line console thats for sure, and if it was people would be moaning that its too expensive.
