NVIDIA GH200 Grace Hopper
A Grace CPU and Hopper GPU fused over NVLink-C2C into one coherent superchip.
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.
GH200 bonds a 72-core Grace CPU to an H100-class GPU with a 900 GB/s coherent link, giving the GPU direct access to up to 480 GB of LPDDR5X alongside its own HBM. It pioneered the CPU+GPU superchip pattern that GB200 scaled up, and powers systems like the Alps and Isambard-AI supercomputers.
