tepping Further into the Era of AI and GPU-Accelerated HPC
Moving beyond pure CPU applications, the NVIDIA GH200 Grace Hopper Superchip is built on a combination of an NVIDIA Grace™ CPU and an NVIDIA H100 Tensor Core GPU for giant-scale AI and HPC applications. Utilizing the same NVIDIA® NVLink®-C2C technology, combining the heart of computing on a single superchip, forming the most powerful computational module. The coherent memory design leverages both high-speed HBM3 or HBM3e GPU memory and the large-storage LPDDR5X CPU memory. The superchip also inherits the capability of scaling out with InfiniBand networking by adopting NVIDIA BlueField®-3 DPUs or NICs, forming a system connected with a speed of 100GB/s for ML and HPC workloads. The upcoming NVIDIA GH200 NVL32 can further improve deep learning and HPC workloads by connecting up to 32 superchips through the NVLink Switch System, a system built on NVLink switches with 900GB/s bandwidth between any two superchips, making the most use of the powerful computing chips and extended GPU memory.
