The Grace Hopper Superchip is an NVIDIA module that fuses a Grace Arm-based CPU and a Hopper GPU on one package, linked by a coherent NVLink-C2C interconnect far faster than PCIe. The tight coupling gives the GPU low-latency access to large CPU-attached memory, benefiting workloads with big datasets or embeddings. It represents the CPU-GPU superchip approach increasingly used in AI and HPC nodes.
