Steam Machine Specifications: Valve's SteamOS Mini PC

Valve officially introduced Steam Machine, a compact mini PC powered by SteamOS — an attractive alternative for gamers who want a console-like experience but with PC flexibility. Here is a summary and detailed specifications of this device.

Steam Machine comes with a compact body measuring 152 × 162 × 156 mm and weighing about 2.6 kg, designed as a living-room-friendly device yet powerful enough for modern gaming. One important technical point is the use of two separate chipsets — standalone processor and GPU — so the Steam Machine relies on a discrete GPU for enhanced graphics performance.

Performance & Gaming Capabilities

Valve claims the Steam Machine can run various modern titles at 4K resolution with an average of 60 FPS when combined with upscaling technologies like AMD FSR. The combination of efficient Zen 4 CPU and discrete RDNA 3 GPU provides a balance between CPU-bound tasks and graphics capabilities, making it suitable for gaming, streaming, and multimedia tasks.
