Valve seems to be testing ARM64 and Android support on Steam, as per a new SteamDB leak. Popular titles like Left 4 Dead 2 and Garry's Mod are being tested with "proton-arm64" tags, among others. This could hint towards new future Valve hardware running on ARM64 architecture.
Going by Apple’s transition from Intel to ARM, an ARM-based Steam Deck would be a no-brainer. They could make it a lot less bulky, ditch the cooling fans and still bump up performance.
It’s not a no brainer. If they want to run x68-64 games on it, they need good tools like Apple’s Rosetta. It would definitely decrease performance and lower the number of compatible games.
