AMD’s driver 26.9.2 has potentially added the PS6 and Steam Deck 2 GPUs in its list of upcoming graphics cards.
As spotted by AnandTech forum member SixPie, the latest Windows driver introduces three previously unseen AMD GPU codenames: “ATlite3,” “AT2” and “Gainsborough,” possibly linked to linked to the PS6 and the Steam Deck 2. Medusa, another upcoming architecture, had already appeared in earlier drivers.
ATLite 3 could be a cut-down version of AT3, potentially featuring around 15–20 Workgroup Processors (WGPs). Known hardware insider Kepler_L2, suggested that ATLite 3 could be the GPU codename for Orion, believed to be associated with the PS6 SoC. The theory draws a parallel with the PS5, where AMD reportedly used “Navi 10 Lite” as the GPU codename for the current-gen PlayStation console. The “Lite” indicates a similar naming convention.
As for Gainsborough, the name appears to have a possible connection to Valve’s first handheld. The original Steam Deck’s Aerith SoC was named after Aerith from Final Fantasy VII, whose full name is Aerith Gainsborough. More importantly, a shipping-manifest image posted by AnandTech forum member olrak29 appears to show Gainsborough already undergoing silicon validation. Entries dated July 29–30, 2026, describe “skeleton aluminum parts” for test equipment and circuit-board boxes, explicitly naming “GAINSBOROUGH-HSL-VALIDATION-SUPPORT” and “GAINSBOROUGH-HSL-VALIDATION-LID,” with the designation “P-FF6.”
Hardware insider and content creator Moore’s Law Is Dead (MLID) recently claimed that Gainsborough had appeared in AMD documents as a semi-custom APU designed for a specific customer. The chip is reportedly being developed by the GPU maker’s S3 team and is said to use TSMC’s N3P 3nm process, an efficiency-focused variant of the company’s 3nm technology.
MLID claimed that some of the personnel working on Gainsborough have also worked on recent PlayStation APUs. He believes Gainsborough could be a custom chip rather than a conventional APU intended for mainstream laptops and desktops. Based on the leaked specs, the insider expects a Steam Deck 2 powered by Gainsborough to feature between 4 and 8 Zen 6C or other low-power cores, alongside 12 to 24 RDNA 5 or other recent-generation RDNA compute units.
