The Steam Deck is a handheld gaming computer produced by Valve Corporation, designed to run games available on its Steam storefront. Built upon the experiences gained from Valve's earlier ventures with the original 2015 Steam Machine and the Steam Controller, the Steam Deck integrates a custom AMD APU and SteamOS, a Linux-based operating system. The Steam Deck represents Valve's pivot towards a fully in-house hardware development approach, following the challenges faced with Steam Machines' reliance on OEMs and the requirement for native Linux game support.
