Definition: DGX Spark

A desktop AI computer from NVIDIA designed for inference (user execution) on large language models as well as training small models. Originally Project DIGITS, the DGX Spark uses the scaled-down GB10 Grace Blackwell Superchip from NVIDIA. Showcased at CES 2025 and the size of a mini PC, 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 Sparks are linked together via NVIDIA's ConnectX networking.

NVIDIA subsequently introduced a chip for powering Windows computers (see N1X). 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.)
