Leaked AMD Gainsborough APU details suggest a three-generation performance leap for the Steam Deck 2

A leak attributed to Moore's Law Is Dead identifies a new semi-custom AMD APU codenamed "Gainsborough" as the likely processor for the Steam Deck 2. The codename follows Valve's established naming convention, as the original Steam Deck's "Aerith" chip shares a name with the Final Fantasy VII character Aerith Gainsborough. This new processor is reportedly built on TSMC’s N3P 3nm process, a significant advancement over the 7nm and 6nm nodes used in previous models. Rumored specifications include between four and eight Zen 6C CPU cores and 12 to 24 RDNA 5 compute units, representing a three-generation jump over the current Zen 2 and RDNA 2 architecture. This hardware configuration is expected to enable the handheld to run current-generation console titles at a stable 30 FPS while maintaining a 15-watt power target for battery efficiency. The video speculates a release window between 2027 and 2028, citing ongoing component supply challenges. Furthermore, the Gainsborough chip reportedly shares architectural similarities with hardware Sony is developing for a future PlayStation 6 handheld, potentially streamlining optimization for cross-platform titles. Valve is expected to retain X86 architecture to ensure continued compatibility with the existing Steam library and SteamOS ecosystem.

Valve is expected to retain X86 architecture to ensure continued compatibility with the existing Steam library and SteamOS ecosystem.

The leaked AMD "Gainsborough" APU is identified as the successor to the original Steam Deck's "Aerith" processor. The new chip is reportedly manufactured using TSMC's N3P 3nm process for enhanced power efficiency.

Potential hardware specifications include up to eight Zen 6C CPU cores and 24 RDNA 5 compute units. This architecture represents a three-generation leap over the Zen 2 and RDNA 2 components in the current Steam Deck.

The Steam Deck 2 is projected to launch between 2027 and 2028 depending on global component availability. The Gainsborough APU may share architectural traits with Sony's rumored PlayStation 6 handheld hardware codenamed "Canis."

Valve intends to stick with X86 architecture to maintain seamless compatibility with the existing Steam library.
