Nvidia has announced two products: the GB200 NVL4, a monster quad-B200 GPU module featuring two Grace CPUs, and the H200 NVL PCIe GPU, aimed at air-cooled data centers.
The GB200 Grace Blackwell NVL4 Superchip is an even more potent variant of the standard (non-NVL4) dual-GPU variant, featuring a whopping four B200 Blackwell GPUs hooked up to each other with NVLink and two Grace ARM-based CPUs all on one motherboard. The solution is aimed at HPC and AI-hybrid workloads featuring a whopping 1.3TB of coherent memory. Nvidia advertises the GB200 NVL4 as having 2.2X the simulation, 1.8X the training, and 1.8X the inference performance of the Nvidia GH200 NVL4 Grace Hopper Superchip — its direct predecessor.
