Valve unveils compact Steam Machine for 2026 | JQJO

Valve unveiled a new Steam Machine, a compact 6 inch cube running Linux based SteamOS and Proton to play Windows games, shipping in early 2026 where Steam Deck is sold. Promising background updates and about six times Deck power, it uses two AMD chips—Zen 4 CPU and discrete RDNA 3 GPU—inside a 3.8 liter chassis with custom cooling and an internal PSU. Upgrades are limited to the SSD and, with effort, RAM. It supports twin displays, USB and Ethernet, works with a new Steam Controller and Steam Frame headset, and pricing not finalized but comparable to a similar PC.
