Whistler

Block Diagram

AMD's Whistler GPU uses the TeraScale 2 architecture and is made using a 40 nm production process at TSMC. With a die size of 118 mm² and a transistor count of 716 million it is a small chip. Whistler supports DirectX 11.2 (Feature Level 11_0). For GPU compute applications, OpenCL version 1.2 can be used. It features 480 shading units, 24 texture mapping units and 8 ROPs.
