The new NVIDIA GB200 Grace Blackwell Superchip is a processor for trillion-parameter-scale generative AI, with 40 petaFLOPS of AI performance, a whopping 864GB of ultra-fast HBM3E memory with an even more incredible 16TB/sec of memory bandwidth.

Each of the new GB200 Grace Blackwell Superchips will feature 2 x B200 AI GPUs and a single Grace CPU with 72 Arm-based Neoverse V2 cores. Alongside the 864GB HBM3E memory pool, 16TB/sec memory bandwidth is joined by a super-fast 3.6TB/sec NVLink connection.

NVIDIA has its new GB200 compute notes with 18 compute trays that support an incredible 36 x Grace CPUs and 72 x Blackwell GPUs, with each of the racks featuring ConnectX-800G Infiniband SuperNIC and Bluefield-3 DPU (with 80GB/sec of memory bandwidth) for in-network computing. NVIDIA uses its latest NVLink switches, which feature 8 ports at 1.8TB/sec each, for up to 14.4TB/sec of aggregate bandwidth. Impressive stuff, NVIDIA.

NVIDIA promises a game-changing 30x performance boost for AI operations with its new GB200 Grace Blackwell Superchip over the current H200 Grace Hopper Superchip.
