How it compares to Windows I wouldn’t know. I did use an Intel Arc for a while on Linux but switched to AMD for performance and idle power draw before the start of 2025. It was stable though with Steam Proton games and general day to day usage. Probably pretty good performance today relative to what it can do on Windows today compared to 2023-2024 when I was using Intel

When I first got the card, Switch emulation did not work. I think it was around mid 2024 when it started to work well

I’m betting on a $700/$800 Steam Deck 2 when that launches and that being a solid deal. PS6 and it’s rumored 36GB of memory, don’t hold your breath for a release
