Valve says the Steam Deck 2 needs a chip that doesn't exist yet

Valve is deliberately holding off on a Steam Deck 2 until a chip exists that can deliver a generational performance leap without sacrificing the 3–15W power envelope needed for 2–6 hours of battery life. Rather than releasing incremental updates, Valve is treating the Steam Deck like a console platform, waiting for AMD's RDNA 5 GPU architecture and Zen 6 CPU cores to converge. This approach preserves the fixed hardware target that lets developers optimize for a single spec baseline. Based on AMD's roadmap, a Steam Deck 2 is tentatively expected in late 2026 or 2027.
