Rumors suggest that AMD's upcoming 'Gainsborough' APU could be the engine behind the long-awaited Steam Deck 2. The codename, mirroring the 'Aerith Gainsborough' naming scheme used for the original Steam Deck's 'Aerith' APU, hints at a next-generation device rather than an incremental update.
While details are scarce, the 'Gainsborough' chip is reportedly built on TSMC's N3P manufacturing node. This advanced process is expected to offer improved efficiency, a critical factor for battery life in a handheld gaming device. This aligns with Valve's stated desire for the Steam Deck 2 to represent a substantial performance increase over the current model, not just a minor improvement.
Further speculation indicates that 'Gainsborough' will feature AMD's next-generation Zen 6 CPU and RDNA 5 GPU architectures. These are the same architectures anticipated for upcoming consoles from Microsoft and Sony, as well as future PC hardware. For context, the current Steam Deck's 'Aerith' and 'Sephiroth' APUs utilize RDNA 2 graphics. A jump to RDNA 5, potentially with an increased number of Compute Units and higher clock speeds, could deliver the significant performance uplift Valve is aiming for.
Moore's Law Is Dead, the YouTube channel reporting these rumors, has a track record of accurate leaks. However, as with all unconfirmed information, this should be approached with caution. The channel suggests that the 'Gainsborough' chip could be ready by late next year or early 2028, potentially targeting a release around that timeframe.
The timing of a potential Steam Deck 2 launch may also be influenced by current market conditions, including the ongoing impact of AI-driven demand on memory prices. Valve may opt to delay the release to ensure better component availability and more stable pricing.
