NVIDIA DGX Spark 128GB · 4TB

The NVIDIA DGX Spark is a compact personal AI supercomputer built on the NVIDIA Grace Blackwell architecture and powered by the GB10 Superchip. It pairs a 20-core Arm CPU (10 Cortex-X925 plus 10 Cortex-A725) with an integrated Blackwell GPU and 128GB of LPDDR5x unified memory, so the CPU and GPU share one coherent memory pool. This makes it purpose-built for AI developers, researchers, and data scientists who need to prototype, fine-tune, and run inference on large models locally rather than renting cloud capacity. A 4TB NVMe solid-state drive gives ample room for datasets, checkpoints, and model weights on-device.

The system ships with the NVIDIA DGX software stack and connects over 10GbE wired LAN, Wi-Fi 7 (802.11be), and Bluetooth 5.3. Rear I/O includes four USB 4.0 Type-C (Gen 3) ports, one HDMI output, and an RJ-45 jack. Housed in a horizontal desktop chassis measuring 5.91 x 5.91 x 1.99 inches and weighing just 2.65 lbs, it slots onto a desk without the footprint of a tower or rack. NVIDIA backs it with a 1-year limited parts and labor warranty.
