The Gainsborough APU, a semi-custom AMD chip, returned to the radar on Thursday as a candidate for the Steam Deck 2. There is no announcement from Valve or AMD. What exists is a rumor cross-checked by PC Gamer, The Verge and Notebookcheck, based on the Moore's Law Is Dead channel, mentions in AMD drivers and import records cited by IT Home.
What the rumor claims
According to those reports, the Gainsborough APU would be a semi-custom processor, built for a specific customer, manufactured on TSMC's N3P process — the most efficient variant of the 3 nm family. Moore's Law Is Dead ties the project to AMD's S3 team and talks about a mix of Zen 6 cores and RDNA 5 graphics. None of this has been confirmed by the companies.
The nickname stands out because the original Steam Deck uses the Aerith APU, named after the Final Fantasy VII character. Gainsborough is Aerith's surname. The Verge notes that the FF6 package would measure about 25 mm by 25 mm, a size also associated, in another leak, with the upcoming Ryzen Z3 and Z3 Extreme for handhelds. The same outlet treats the Valve link as plausible, but still speculative.
When a Steam Deck 2 could exist
The window cited by Moore's Law Is Dead is late 2027 or sometime in 2028 for the chip to be ready. PC Gamer notes that Valve does not seem to be in a hurry, partly because of the memory shortage tied to AI demand, which has already affected other recent hardware launches from the company, such as the Steam Machine. The first Steam Deck reached the market about four and a half years ago.
What is still unknown
There is no price, announcement date, battery life or game list. It is also not confirmed that the chip's customer is Valve: a small semi-custom package could fit other handhelds. Until then, the Gainsborough APU is a clue, not a product.
The reports are at PC Gamer, The Verge and Notebookcheck.
