Leaks Suggest Valve's Steam Deck 2 Uses AMD's 'Gainsborough' Chip

Key points

• AMD driver documents reveal a new chip codenamed 'Gainsborough,' which leakers link to the Steam Deck 2.
• The chip is built on TSMC's N3P 3nm process, promising better efficiency than the current Steam Machine.
• The codename 'Gainsborough' is the surname of Aerith, the character after whom the original Steam Deck chip was named.
• Valve has stated it wants a 'generational leap' in performance, not just a minor upgrade, for the sequel.
• A release window of late 2027 or early 2028 is suggested, though pricing remains uncertain due to RAM costs.

Background

Valve has maintained strict secrecy regarding the Steam Deck 2, previously stating in September 2026 that its plans remain unchanged despite the global RAM price surge. The company has emphasized the need for a significant performance jump over the 2022 original. Recent leaks of Valve's internal data have also highlighted the company's long history of prototype development, though no specific hardware details for the new handheld were found in those archives.

How outlets are covering it

Gizmodo and PC Guide are optimistic, citing the 'Gainsborough' codename and 3nm process as strong indicators of a major upgrade, potentially featuring Zen 6 and RDNA 5 architectures. The Verge is more skeptical, noting that semi-custom chips do not always end up in their intended devices and that the leak lacks concrete proof of a direct link to Valve. All outlets agree that the naming convention (Aerith Gainsborough) is a compelling hint, but only Gizmodo and PC Guide explicitly link the chip to the Steam Deck 2 timeline.

Why it matters

The Steam Deck 2 is expected to redefine the handheld PC market. If the leaks are accurate, the device will offer significantly better battery life and performance, potentially challenging console handhelds like the PS6. However, the high cost of RAM may result in a price tag well above the original $400, impacting consumer adoption.

What to watch

Consumers should expect official announcements or further leaks in the coming months. A release in late 2027 or early 2028 is the current consensus. Pricing will likely be influenced by the ongoing memory crisis, with Valve's Pierre-Loup Griffais confirming that RAM costs have not changed their development plans but have likely impacted the final price.
