NVIDIA DGX Spark Details

NVIDIA DGX Spark

Supercomputer-class AI, on your desk.

Built on the Grace Blackwell architecture — the same generation powering the world's largest AI data centres — DGX Spark delivers data-centre AI in a desktop form factor, drawing the power of a small appliance.

1 PFLOP
FP4 AI performance
240 W
Total power draw
128 GB
Unified LPDDR5x
Coherent Unified Memory

One address space. No PCIe bottleneck.

The CPU and GPU share 128 GB of LPDDR5x at full bandwidth. Large language models and multimodal workloads that demand two GPU nodes on conventional hardware run in a single coherent memory space here — no copies, no partitioning.

Ready Out of the Box

Plug in and train.

Ships with NVIDIA AI Enterprise pre-installed. PyTorch, TensorFlow, TensorRT, and RAPIDS are ready the moment you power on. The ConnectX-7 NIC links nodes at 200 Gbps without an external switch — and you can scale out to DGX Cloud when the job grows.
