NVIDIA has officially launched the DGX Spark, a compact AI supercomputer that delivers data-center-class performance in a desktop-sized form factor. Announced at GTC 2025, DGX Spark is designed to democratize access to high-performance AI, enabling developers, researchers, and startups to work with massive models locally—without the immediate need for cloud infrastructure.

This release marks a pivotal moment in AI computing, bridging the gap between personal workstations and enterprise-grade systems.

Core Architecture and Performance

At the heart of DGX Spark is the NVIDIA GB10 Grace Blackwell Superchip, a System-on-a-Chip (SoC) that fuses CPU and GPU capabilities with a unified memory architecture.

• Processor: 20-core ARM CPU with 10 high-performance Cortex-X925 cores and 10 energy-efficient Cortex-A725 cores.
• GPU: Integrated Blackwell architecture GPU with fifth-generation Tensor Cores.
• AI Performance: Up to 1 petaFLOP at FP4 precision, leveraging sparsity for optimized throughput.
• Memory: 128 GB of coherent LPDDR5x unified memory, supporting inference and fine-tuning of models up to 200 billion parameters.
• Storage: 4 TB NVMe M.2 SSD with self-encryption for secure, high-speed data access.
• Form Factor: Ultra-compact at 150 x 150 x 50.5 mm and just 1.2 kg—small enough to fit on any desk.
• Connectivity: 10 GbE port and ConnectX-7 Smart NIC, enabling two DGX Spark units to be linked for models up to 405 billion parameters.

Software Ecosystem and Integration

DGX Spark runs NVIDIA DGX OS, based on Ubuntu Linux, and includes the full NVIDIA AI software stack:

• CUDA libraries and optimized frameworks for deep learning, data science, and simulation.
• NVIDIA NIM for deploying pre-trained models with minimal setup.
• Seamless migration to DGX Cloud or larger DGX systems with no code changes required.

This "develop on your desk, deploy in the cloud" model addresses common pain points such as limited local resources and cloud dependency, while offering a secure environment for sensitive workloads.

Use Cases and Target Users

DGX Spark is tailored for a broad spectrum of users:

• Individual AI Developers and Researchers
  Enables local experimentation, fine-tuning, and inference without relying on cloud credits or shared infrastructure.

• Startups and Small Businesses
  Offers an affordable, high-performance entry point into enterprise-grade AI development.
