SteamDeck’s isn’t the same at all. It is a fake sleep: “Go to sleep but you can finish downloading whatever you need before” (inside the steam software, outside of it it has no idea).

On OLED screens you get to have the screen powered off. On LCD we see the screen is still powered. Maybe they just turn the brightness to the minimum and send black color of pixels?

Anyway, once the download queue finish, the SteamDeck goes to proper hibernation and does only get to wake up when using the power button. Not at any notification or when a background process want it like I see explained on comments in this thread.

Edit: The SteamDeck version looks a lot more like the “Finish the update and restart/shutdown/hibernate button”

I really dodged a bullet upgrading from my 1070Ti to the last AMD (9070XT or I misremembered?) for the black Friday. Lowest price of the generation just before RAM’s price skyrocketed.

My SO is not so lucky…

Maybe we should use this card for under TV computers with Windows… sadly?
