NVIDIA Launches DGX Spark, the World’s Smallest AI Supercomputer

NVIDIA has unveiled the DGX Spark, a compact AI supercomputer designed for desktop use, set to begin shipping this week. The device combines GPUs, CPUs, networking, CUDA libraries, and AI software into a single unit. Integrated with the GB10 Grace Blackwell Superchip, it delivers up to 1 petaflop of AI performance and 128 GB of unified CPU-GPU memory.

CEO Jensen Huang positioned the DGX Spark as a return to NVIDIA's founding mission of democratizing AI computing. "In 2016, we built DGX-1 to give AI researchers their supercomputer," Huang said, referencing the system that powered OpenAI's early work. "With DGX Spark, we place an AI computer in the hands of every developer to ignite the next wave of breakthroughs."

The system enables local inference on models with up to 200 billion parameters and fine-tuning for models up to 70 billion parameters, reducing reliance on cloud services. It features ConnectX-7 200 Gb/s networking and NVLink-C2C technology, offering five times the bandwidth of fifth-generation PCIe.
