Overview
The NVIDIA DGX Spark is a compact personal AI supercomputer built on the NVIDIA GB10 Grace Blackwell Superchip. It pairs a 20-core Arm CPU (10x Cortex-X925 + 10x Cortex-A725) with a Blackwell GPU delivering up to 1 PFLOP of FP4 tensor performance, 128GB of coherent unified memory, and 4TB of self-encrypting NVMe storage. With ConnectX-7 200 Gbps networking, it is designed to run large AI and machine-learning models locally in a 150mm cube chassis.
Key Highlights
- NVIDIA GB10 Grace Blackwell Superchip combining a 20-core Arm CPU with Blackwell GPU in one unified design
- 128GB of coherent unified LPDDR5x system memory (273 GB/s) for large AI and machine-learning workloads
- Up to 1 PFLOP of FP4 tensor performance (5th-gen Tensor Cores, 4th-gen RT Cores) for the DGX platform
- ConnectX-7 200 Gbps networking plus 10GbE wired Ethernet and Wi-Fi 7 / Bluetooth 5.4 wireless
- Compact 150mm cube chassis (1.2 kg) with 240W power supply (140W GB10 TDP) and AI-optimized DGX OS
