Definition: DGX Spark

A desktop AI computer from NVIDIA designed to prototype large language models. Originally known as Project DIGITS, the DGX Spark machine uses the scaled-down GB10 Grace Blackwell Superchip from NVIDIA. Showcased at CES 2025 and about the size of a mini PC, it was designed to support AI training as a peripheral to a desktop computer.

The GPU in Spark is from 5 to 10% as powerful as NVIDIA's GB200 Superchip; however, it is expected to support AI models with up to 200 billion parameters and up to 400 billion when two units are linked together via NVIDIA's ConnectX networking. See DGX, Blackwell and NVMe.

An AI Computer - Really?

The computer looks rather harmless sitting on a desk, but it is actually capable of one quadrillion floating point calculations per second (one petaFLOPS). The machine comes with 128GB of memory and up to 4TB of NVMe storage. (Image courtesy of NVIDIA Corporation.)
