Bandwidth gains over the Deck 1 should be substantial, but they heavily depend on the type of memory utilized by Valve.

The memory controller would be limited to LPDDR 128-bit. On the graphics side, the RDNA3 iGPU could feature 4 work groups with 8 compute units and a total of 1024 stream processors. This could lead to 24-35% higher PPC and possibly 50% overall CPU boost in performance over the Steam Deck 1 processor with Zen 2 + RDNA2. It could integrate a maximum of 4 cores with 8 threads boosting to 4 GHz. Pricewise, it will cost more than Van Gogh as it is produced on a newer TSMC node. Currently codenamed “Little Phoenix,” this cut-down version is rumored to be utilized in Steam’s Deck 2 handheld console, which could be launched in Q4 2023 at the soonest.Īccording to MLID, the "Little Phoenix" would feature a 110-150 mm2 die, which roughly puts it between Van Gogh and Mendocino. Sources close to Youtuber Moore’s Law Is Dead suggest that AMD is planning to launch a ultra low-power version of the upcoming "Phoenix" mobile processors based on the Zen 4 CPU cores and the RDNA3 graphics architecture.
