Block Diagram

AMD's Caicos GPU uses the TeraScale 2 architecture and is made using a 40 nm production process at TSMC. With a die size of 67 mm² and a transistor count of 370 million it is a very small chip. Caicos supports DirectX 11.2 (Feature Level 11_0). For GPU compute applications, OpenCL version 1.2 can be used. It features 160 shading units, 8 texture mapping units and 4 ROPs.
