Yep! The article title is a bit misleading, as the Steam Machine is still x86_64. Which is good imo: that’ll have better compatibility and the power draw/thermals matter less there than in a handheld or headset.
The Frame is the arm-based hardware Valve is going to be shipping.
But their work on FEX is taking ARM compatibility into the future, much like how their work on Wine/Proton has taken Linux compatibility to a new level.
Anyways, I agree with the article, that it’s going to extend to more than the Frame as support matures. ARM CPUs (or RISCs in general) are the future for non-desktop processors; I’d argue Apple has already been there with their M-series laptops, though not to nearly the same extent with gaming.
