DGX Spark

The NVIDIA DGX Spark is a desktop-sized AI supercomputer powered by the GB10 Grace Blackwell Superchip, delivering 1 petaFLOP of performance for local model development.

DGX Spark brings data-center-grade power to the desk by integrating a 20-core Arm CPU and a Blackwell GPU into a single, power-efficient package. With 128GB of coherent unified memory and support for the FP4 data format, it enables developers to prototype and fine-tune models with up to 200 billion parameters locally. The system ships with the full NVIDIA AI software stack preinstalled (including DGX OS and CUDA), ensuring seamless code migration to larger DGX clusters or the cloud. For massive workloads, the built-in ConnectX-7 networking allows users to link two Spark units to handle models as large as Llama 3.1 405B.
