Steam Deck GPU: specs and benchmarks

Summary

AMD started Steam Deck GPU sales 25 February 2022. This is a desktop graphics card based on a RDNA 2.0 architecture and made with 7 nm manufacturing process. It is primarily aimed at gamer market. 16 GB of LPDDR5 memory clocked at 1.38 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of 88 GB/s.

Its manufacturer default version has a length of 298 mm. No additional power connector is required, and power consumption is at 15 Watt.
