AI Computer : Nvidia GB10 Grace Blackwell in NVIDIA DGX Spark Package and Main PCB detailed analysis

NVIDIA DGX Spark™	Main PCB

Product outline

The NVIDIA DGX Spark™ is one of the world’s smallest AI supercomputers equipped with the GB10 Grace Blackwell Superchip. Despite its desktop-sized form factor, it delivers up to 1 petaflop of performance and provides a highly efficient system capable of running 200‑billion‑parameter generative AI models locally.
The GB10 Grace Blackwell Superchip is NVIDIA’s latest AI‑focused SoC, announced in 2025, and is an innovative chip that integrates a CPU and GPU to achieve petaflop‑class computing performance.
The GB10 combines the Grace CPU and Blackwell GPU using 2.5D integration technology and features a compact, high‑efficiency package with 128 GB of unified memory.
