In collaboration with AMD, Valve created a custom hybrid processor for Steam Deck, optimized for a portable gaming PC. The performance of this processor, based on Zen 2 and RDNA 2 architectures, is more than sufficient to run modern high-budget games.
The device is designed for comfortable long gaming sessions and is equipped with full-size controls arranged in a convenient layout. The built-in 40 Wh Steam Deck battery provides several hours of gameplay in most scenarios. When streaming from other devices, playing lightweight 2D games, or browsing the web, battery life can reach 7–8 hours.
The fast suspend and resume feature has been added to SteamOS. Pressing the power button pauses the game and puts Steam Deck into sleep mode. Pressing the power button again turns the device back on and allows gameplay to continue from the same point.
