NVIDIA's GB202 GPU uses the Blackwell 2.0 architecture and is made using a 5 nm production process at TSMC. With a die size of 750 mm² and a transistor count of 92,200 million it is a very big chip. GB202 supports DirectX 12 Ultimate (Feature Level 12_2). For GPU compute applications, OpenCL version 3.0 and CUDA 12.0 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 24576 shading units, 768 texture mapping units and 192 ROPs. Also included are 768 tensor cores which help improve the speed of machine learning applications. The GPU also contains 192 raytracing acceleration cores.
