A new class of computer for AI builders and researchers

The PNY NVIDIA DGX Spark GB10 redefines what a desktop workstation can do. Designed for developers, data scientists, and AI researchers who need real supercomputer capability without a server room, it delivers up to 1 petaFLOP of AI compute at FP4 precision from a compact, champagne-gold enclosure that weighs just 1.2 kg. Powered by the NVIDIA Grace Blackwell architecture — the same generation driving the world's most advanced data centres — the DGX Spark lets you prototype, fine-tune, and run inference on large language models and generative AI workloads entirely on your desktop, then deploy seamlessly to the data centre or cloud when you are ready to scale.

128 GB of unified memory: no model too large for your desk

Tired of hitting memory walls mid-training and waiting on cloud queues to continue your work? The DGX Spark's 128 GB of LPDDR5x unified system memory — shared coherently between the CPU and GPU — removes that bottleneck entirely. With a 256-bit memory interface delivering 273 GB/s of bandwidth, you can run AI models of up to 200 billion parameters locally in a single system. Link two DGX Spark units together via NVIDIA ConnectX networking and the combined capacity extends to AI models of up to 405 billion parameters, giving your team a compact, high-performance AI cluster without the infrastructure overhead.

Grace Blackwell silicon: 5th-generation Tensor Cores at your fingertips

At the heart of the DGX Spark is the NVIDIA GB10 Superchip, combining a 20-core Arm CPU — ten Cortex-X925 performance cores paired with ten Cortex-A725 efficiency cores — with a Blackwell-generation GPU featuring 5th-generation Tensor Cores and 4th-generation RT Cores. This architecture is purpose-built for the compute demands of modern AI: transformer training, large-scale inference, retrieval-augmented generation, and multi-modal workloads all benefit from the raw arithmetic throughput that previously required a rack of servers. The preinstalled NVIDIA AI software stack — including frameworks, libraries, and pretrained models — means you can be productive from the moment you power on.

Enterprise-grade connectivity in a mini form factor

Despite its compact footprint, the DGX Spark is exceptionally well connected. Four USB Type-C ports (three available for peripherals, one powering the unit), a single HDMI 2.1a output supporting up to 8K displays at 120 Hz with HDR, a 10 GbE RJ-45 port for reliable wired networking, and a ConnectX-7 Smart NIC capable of up to 100 GbE ensure that data moves as fast as your models demand. Wi-Fi 7 and Bluetooth 5.3 keep the unit cable-light when you need flexibility. The 4 TB self-encrypting NVMe M.2 drive safeguards your proprietary models and datasets at rest, meeting the security expectations of professional AI development environments.
