AMD Will Develop Gainsborough Chip for Steam Deck 2

Live Poll

Is now a good time to wait for the next generation of handheld gaming devices?

AMD is reportedly developing a new APU codenamed Gainsborough to power the successor to Valve's Steam Deck. The chip is expected to be ready by late 2027 or early 2028, with the Steam Deck 2 launch projected for late 2028.

Why it matters

Valve is seeking a substantial performance leap for its next handheld device rather than incremental upgrades. By utilizing cutting-edge semiconductor nodes, the company aims to significantly enhance efficiency and processing power compared to previous models.

The Gainsborough APU is expected to utilize TSMC N3P production nodes. This represents a significant shift from the 7 nm silicon used in the original Steam Deck Aerith chip.
