NVIDIA GB203

NVIDIA's GB203 GPU uses the Blackwell 2.0 architecture at TSMC. GB203 supports DirectX 12 Ultimate (Feature Level 12_2). For GPU compute applications, OpenCL version 3.0 and CUDA 9.1 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 10752 shading units, 336 texture mapping units and 192 ROPs. Also included are 336 tensor cores which help improve the speed of machine learning applications. The GPU also contains 84 raytracing acceleration cores.
