Definition: Grace Hopper Superchip
Named in honor of Rear Admiral Grace Hopper, the Grace Hopper Superchip from NVIDIA was designed for large-scale AI and high-performance computing. Introduced in 2023 and used in major cloud computing datacenters, the chip contains NVIDIA's ARM-based 72-core Grace CPU and the Hopper H100 GPU that connect to each other via NVLink at 900 Gbps. See DGX and NVLink.

A Note from the Author
As a program director for computer education at the American Management Association in New York in the 1970s, I had the privilege of knowing Grace Hopper. On several occasions, I handled the logistics for the speeches she gave and escorted her to the venues. This Vassar and Yale graduate had a very dry sense of humor, and at 105 pounds, wherever she went in her official naval uniform, adorned with medals, she raised eyebrows. In 1992, Hopper died at age 85. She was unlike anyone else. See nanosecond.
The CPU connects to 480GB of low power (LPDDR RAM and to the outside world via four 16-lane PCIe 5 channels. The GPU uses 18 NVLinks to a network of GPUs and connects to high bandwidth memory (96GB HBM and 144GB HBM3e). See LPDDR SDRAM, PCI Express and high bandwidth memory.
One of the most famous people in the early history of computing, Commodore Grace Hopper became a rear admiral when the rank of commodore was renamed. Commodore Hopper joined the U.S. Naval Reserve in 1943. See Mark I and FLOW-MATIC. (Image courtesy of U.S. Navy.)
