Depends if you want a laptop or something in the form factor of a switch. The rest is irrelevant.
Framework
Discussion around the Framework mission of building products that last longer by making them upgradeable, customizable, and repairable. Consumer electronics can be better for you and for the environment.
Actually there are handheld custom consoles built around the framework main board. So far I've seen 2, so it's probably not something OP uses, still interesting projects.
they are not comparable lol a reasonbly specced fw can cost you over $1200 while you can get a deck for less than half that.
I am in love with the stream deck for games and waiting for the framework for work.
You'd be better off comparing with something like a Lenovo Legion Go or Asus ROG Ally as both of these use an APU (do AMD still use that phrase?) that most closely approximates the 7840U (compare Z1 Extreme) or 7640U (compare Z1).
If you want a handheld, you could theoretically buy an AMD Framework board and go the DIY handheld route but they've only used an Intel board so far, so YMMV.
Then again, you can dock a Legion Go or ROG Ally and essentially get a similarly-performing system to a Framework AMD laptop with a keyboard and screen.
Ultimately, what form factor do you want? The whole point of Framework is the sustainability / noodleability of the platform so if that's what you're after, go Framework.
If you want to play handheld games with AMD 7x40U-ish performance, get a Go or Ally.
The 7840U is a solid upgrade over the steamdeck along with egpu support. If you don't need a handheld but want to game it's a no brainer.
Comparing apples and oranges here.
