I would be surprised if they moved to ARM any time soon, because even if the CPUs can punch that hard, they're definitely not competing on the GPU front, from what I understand of the state of the art outside of Apple, so they're gonna wind up with a dGPU anyway if they did.

Maybe my knowledge is out of date, but I'd be kind of surprised if a Snapdragon can get anywhere near competing with even the existing Steam Deck on GPU performance. Looking at [1] for a ballpark number on Snapdragon GPU performance doesn't seem encouraging.
