Steam Deck 2: Is AMD Gainsborough the chip Valve’s been waiting for?
Leaked entries in AMD driver code and import records have revealed a previously unreported codename, 'AMD Gainsborough,' that appears to be a small semi-custom APU built on TSMC's N3P process. Observers note the name echoes the Steam Deck's original 'Aerith' codename and that package dimensions and rumored Ryzen Z3 family details line up with handheld power envelopes, prompting speculation that Gainsborough could be the chip Valve has been waiting for to enable a Steam Deck 2.
Why It Matters
Valve has said it needs a substantial generational improvement in performance and efficiency before launching a Steam Deck sequel, so evidence of a new small, low-power semi-custom AMD APU could mark a key hardware prerequisite. Confirming such a chip's intended customer and design would be crucial to assessing whether it will actually power a future Steam Deck model.
Key Facts
- Leaked codename: AMD Gainsborough
- Source of leak: AMD driver files reported by Moore's Law is Dead and IT Home
- Packaging size found in import records: FF6 package measuring 25 mm x 25 mm
- Process node reported: TSMC N3P
- Related product family: Rumored Ryzen Z3 and Z3 Extreme handheld chips
Leaked identifiers in recent AMD driver code and related import/export records have surfaced a previously unknown codename, 'AMD Gainsborough,' that appears to describe a compact semi-custom APU. IT Home’s checks of shipping records indicate AMD has dispatched test equipment tied to Gainsborough, which suggests validation work is underway for a specific customer. The chip is reported to use TSMC’s N3P process and to come in an FF6 package measuring 25 mm by 25 mm.
The Gainsborough name has drawn attention because it is the surname of Aerith Gainsborough, the character whose given name inspired the Steam Deck’s original 'Aerith' codename. That coincidence has prompted speculation the new APU could be aimed at a Steam Deck successor. Additional context comes from a leak attributed to Gotou_3rd suggesting AMD’s next handheld Ryzen Z3 family will also use 25 mm by 25 mm packages and target a roughly 15-watt power envelope, similar to the Steam Deck and Steam Deck OLED.
However, several caveats weaken a direct link between Gainsborough and a Steam Deck 2. Semi-custom chips are sometimes repurposed from their originally intended devices, and the original Steam Deck’s Aerith APU reportedly had design origins not exclusive to Valve. Valve itself has not used the Final Fantasy-based names officially; AMD chose those codenames. Moreover, the original Aerith design eventually existed in a smaller 19 mm by 19 mm form for later revisions, so a 25 mm by 25 mm package would be larger than some prior Deck-focused parts.
Valve has repeatedly said it will only build a Steam Deck 2 once a chip offers a meaningful generational leap in performance and efficiency. According to reporting, Valve was still determining 'how and when' to proceed with a sequel even after potential Gainsborough samples would have arrived, and the company has been cautious about committing to timelines following earlier hardware delays. The available evidence suggests Gainsborough is a plausible candidate to meet the kind of hardware leap Valve seeks, but it does not definitively identify the chip as the Steam Deck 2’s CPU-GPU solution.
