Combines 10 performance-focused Cortex-X925 cores and 10 energy-efficient Cortex-A725 cores. The result is a system that can deliver solid performance while using only 240 watts of power. Making it ideal for those seeking a powerful, energy-efficient solution. This CPU architecture strikes a balance between high-speed computing for intensive workloads and low-power consumption for prolonged operation. Making the DGX Spark suitable for both high-performance AI development and energy-conscious users. Whether you’re running large AI models or conducting real-time data analysis, this system delivers without overloading power requirements.
This compact system also includes 128 GB of LPDDR5x RAM and a massive 4 TB NVMe M.2 storage. Together, these components enable the DGX Spark to achieve up to one petaflop of Tensor Core performance. Specifically in FP4 operations, utilizing the sparsity feature. While not faster than Nvidia’s higher-end GPUs like the RTX 5080 or 5090. The DGX Spark’s unified memory provides a unique advantage for AI model developers, eliminating the need for model quantization or GPU VRAM swapping.
Practical Design and Affordability
Despite its power, the DGX Spark is impressively small. Its dimensions of just 150 x 150 x 50.5 mm (5.9 x 5.9 x 2.0 inches) and weight of only 1.2 kg (2.6 lbs.) make it a versatile desktop that can fit in almost any workspace. This compact design is perfect for developers who need a portable. High-performance workstation for AI development without taking up much desk space.
The system runs Nvidia DGX OS, a custom version of the widely-used Ubuntu Linux distribution. This software platform is tailored for AI development, providing developers with the tools needed to fully leverage the system’s hardware capabilities. The DGX Spark’s ability to run demanding AI workloads while using minimal power is a significant advantage for those working in environments where energy consumption is a concern. Its optimized performance allows developers to efficiently run complex AI models locally, speeding up the iteration process. With Nvidia’s OS, users can also access a range of AI-focused libraries and frameworks, streamlining the development and deployment of cutting-edge applications.
