AMD's Navi 31 GPU uses the RDNA 3.0 architecture and is made using a 5 nm production process at TSMC. With a die size of 529 mm² and a transistor count of 57,700 million it is a very big chip. Navi 31 supports DirectX 12 Ultimate (Feature Level 12_2). For GPU compute applications, OpenCL version 2.2 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 6144 shading units, 384 texture mapping units and 192 ROPs. The GPU also contains 96 raytracing acceleration cores.
