AMD's Opal GPU uses the GCN 1.0 architecture and is made using a 28 nm production process at TSMC. With a die size of 77 mm² and a transistor count of 950 million it is a very small chip. Opal supports DirectX 12 (Feature Level 11_1). For GPU compute applications, OpenCL version 2.1 (1.2) can be used. It features 384 shading units, 24 texture mapping units and 8 ROPs.
