Steam Deck 2: Is AMD Gainsborough the chip Valve’s been waiting for?
AMD has leaked a new chip codenamed "Gainsborough" that could power a long-awaited Steam Deck 2. The discovery comes as handheld gaming enthusiasts wait for Valve to release a sequel to the four-and-a-half-year-old original device, which the company has said requires a chip offering "generational leap" improvements in performance and efficiency. However, the original reporter expresses significant caution about whether this chip is genuinely intended for the Steam Deck 2.
Evidence for Gainsborough's involvement includes the naming convention—the original Steam Deck's chip was called "Aerith" after a Final Fantasy VII character, and Gainsborough is that character's surname. The semi-custom chip is built on TSMC's N3P process and measures 25mm by 25mm, with import records suggesting AMD is already shipping test equipment for validation. Yet several factors create uncertainty: semi-custom chips sometimes end up in different products than originally planned, the Final Fantasy codenames are actually AMD's rather than Valve's, and the chip is larger than the original Steam Deck's 19mm by 19mm processor. As of last month, Valve was still determining the timing and approach for a Steam Deck 2.
- AMD leaks Gainsborough chip possibly destined for Steam Deck 2.
- Gainsborough named after Final Fantasy VII, but Steam Deck link uncertain.
- Valve hasn't confirmed Steam Deck 2 plans as of late 2026.

The Steam Deck is a handheld gaming device made by Valve that plays full PC games on the move since launching in late 2021. It proved popular with players, and many have been waiting for an improved sequel that Valve has said would require major advances in processing power and battery efficiency.
A new chip codenamed "Gainsborough" has surfaced in leaked documents and could potentially power this successor. The naming convention hints at the connection: the original Steam Deck's chip was called "Aerith" after a Final Fantasy VII character, and Gainsborough is that same character's surname, suggesting AMD may be following the same naming approach.
Substantial doubt exists about whether Gainsborough is actually destined for the Steam Deck 2, however. Semi-custom chips frequently end up in products other than their initial target, the Final Fantasy naming comes from AMD rather than Valve, and the new chip is physically larger than the original processor, raising questions about compatibility with the handheld's existing design.
