NVIDIA GB200 Grace Blackwell
One Grace CPU + two B200 GPUs: the building block of the NVL72 rack.
You're looking at a chip record: what this processor is, its key specs, who designs, manufactures and supplies its parts, and where it gets used.
GB200 packages a 72-core Grace CPU with two B200 GPUs on one board, coherently linked at 900 GB/s. Thirty-six of them form the GB200 NVL72 — a 120 kW, fully liquid-cooled rack in which 72 GPUs share one NVLink domain and behave, to software, like a single enormous accelerator.
