The Steam Deck 2 has been one of the most talked-about pieces of hardware in PC gaming for years now, and the rumour mill just got a whole lot more interesting. A new AMD APU carrying the codename Gainsborough is circulating in hardware circles as the leading candidate to power Valve's next handheld, and if the naming convention holds up, the chip could represent a serious generational leap for portable PC gaming.

The codename that started it all
Here's the thing about AMD's codename choices: they follow a pattern. The original Steam Deck runs on a custom AMD APU codenamed Van Gogh, and AMD has a well-documented habit of naming its chips after famous artists. Gainsborough fits that lineage perfectly, named after 18th-century English painter Thomas Gainsborough. Final Fantasy 7 fans will also recognise it as Aerith Gainsborough's surname, which has already sent a corner of the internet into a mild frenzy.
But the naming quirk is secondary to what the chip reportedly represents. Gainsborough is expected to sit on a significantly newer process node than Van Gogh, which launched on TSMC's 6nm process back in 2022. A newer node means better power efficiency and more headroom for GPU performance, both of which matter enormously in a handheld form factor where thermal and battery constraints define the ceiling.
What a new APU actually means for handheld performance
The original Steam Deck's Van Gogh APU paired a quad-core Zen 2 CPU with an RDNA 2 GPU. That combination was genuinely impressive for its time, capable of running most PC games at 720p to 800p with reasonable frame rates. The key here is that handheld gaming has moved fast since then. The ROG Ally and Legion Go both shipped with AMD's Ryzen Z1 Extreme, which uses Zen 4 CPU cores and an RDNA 3 GPU, and the performance gap between those devices and the original Steam Deck is measurable.
A Gainsborough-based Steam Deck 2 would presumably close that gap and then some. If AMD moves to Zen 5 CPU cores and RDNA 4 GPU architecture for this chip, the generational uplift over Van Gogh would be substantial. RDNA 4 already demonstrated strong rasterisation and ray tracing gains in the desktop RX 9000 series cards, and a mobile variant tuned for low-wattage operation could translate that into genuinely next-level handheld performance.
Why Valve's timing matters here
Valve has been unusually quiet about a Steam Deck successor. The company has consistently said it plans to iterate on the hardware, but has avoided committing to a timeline. The current Steam Deck OLED, released in late 2023, was a meaningful refresh rather than a new generation, improving the display and battery life while keeping the same Van Gogh silicon underneath.
The competitive pressure from ASUS, Lenovo, and MSI has been building steadily. Those devices run Windows by default and carry higher price tags, but they also offer noticeably more raw performance. Valve's advantage has always been SteamOS, price accessibility, and a tightly integrated software experience. Pairing that with a genuinely modern AMD APU would give the Steam Deck 2 a compelling argument on every front.
For players who spend time optimising their setup for handheld play, the kind of hardware jump Gainsborough implies could change what's possible at the 15W to 20W power envelope that handheld devices typically operate within.

What to watch for next
AMD's product roadmaps typically surface through regulatory filings, driver code references, and supply chain leaks before any official announcement. Gainsborough appearing in those channels at all suggests the chip is real and progressing through development. Whether it lands exclusively in a Steam Deck 2 or also powers other handheld devices from third-party manufacturers remains an open question.
Valve tends to announce hardware on its own schedule, often with minimal lead time. The original Steam Deck was revealed in July 2021 and shipped in February 2022. If Gainsborough is far enough along in development to be circulating in hardware rumours now, a formal announcement from Valve could come sooner than most expect.
