AMD's Hainan GPU uses the GCN 1.0 architecture and is made using a 28 nm production process at TSMC. With a die size of 56 mm² and a transistor count of 690 million it is a very small chip. Hainan supports DirectX 12 (Feature Level 11_1). For GPU compute applications, OpenCL version 2.1 (1.2) can be used. Unknown texture mapping units and Unknown ROPs. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support).
