AMD's Navi 32 GPU uses the RDNA 3.0 architecture and is made using a 5 nm production process at TSMC. With a die size of 346 mm² and a transistor count of 28,100 million it is a large chip. Navi 32 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 3840 shading units, 192 texture mapping units and 128 ROPs. The GPU also contains 60 raytracing acceleration cores.
