This listing is a bundle of two NVIDIA DGX Spark units, each built around the GB10 superchip, combined for roughly 1 petaflop of FP4 AI compute and 128GB of memory, with ConnectX-7 networking and the DGX Spark bundle cable supplied specifically to link two units together into a single larger AI compute cluster, plus an EU power cable. DGX Spark is NVIDIA's compact desktop AI supercomputer aimed at developers who need to prototype, fine-tune and run large AI models locally; pairing two via the bundle cable effectively doubles available compute and memory for larger models or faster iteration than a single unit alone.
