AMD's Navi 23 GPU uses the RDNA 2.0 architecture and is made using a 7 nm production process at TSMC. With a die size of 237 mm² and a transistor count of 11,060 million it is a medium-sized chip. Navi 23 supports DirectX 12 Ultimate (Feature Level 12_2). For GPU compute applications, OpenCL version 2.1 can be used. Additionally, the DirectX 12 Ultimate capability guarantees support for hardware-raytracing, variable-rate shading and more, in upcoming video games. It features 2048 shading units, 128 texture mapping units and 64 ROPs. The GPU also contains 32 raytracing acceleration cores.
