AMD Gainsborough APU leaked, potentially powering Valve Steam Deck 2

Leaked benchmarks from OpenBenchmarking have revealed details regarding an AMD APU codenamed ‘Gainsborough,’ which is widely speculated to be the successor chip for Valve’s Steam Deck 2.

The engineering sample features a CPU with 6 cores and 12 threads, representing a 50% increase in core count over the original Steam Deck. The chip is reportedly paired with 24GB of LPDDR5X memory running at 9,600 MT/s, a significant upgrade from the current model’s 16GB of LPDDR5 at 6,400 MT/s.

While specific GPU architecture remains unconfirmed, rumors suggest it may utilize RDNA 5 technology. Early FurMark testing showed a score of 3,508 at 768p resolution, which is comparable to the original Steam Deck’s 3,323 score at 800p. However, experts note that these results are preliminary, as the sample is running on early drivers and lower clock speeds, meaning final performance could be substantially higher.
