DGX Spark brings Blackwell inference to desktops

The DGX Spark is a category-defining moment for local AI development, bridging the gap between consumer workstations and data-center clusters. The GB10 Grace Blackwell Superchip integrates 128GB LPDDR5X unified memory for massive model capacity on a single SoC. Optimized for vLLM using NVFP4 quantization, it runs 100B+ parameter models with minimal accuracy loss. Integrated ConnectX-7 networking supports linking two units via NVLink for 405B parameter model support. An ultra-compact 150mm footprint powered via USB-C PD enables true portable supercomputing for on-premise development. Although the 273 GB/s memory bandwidth is a bottleneck compared to H100, it provides a private, cloud-free inference path for enterprise data.
