Nvidia DGX Spark Review the GB10 Machine Is So Freaking Cool (www.servethehome.com)

NVIDIA’s compact DGX Spark (GB10) has arrived for review as a pre-production mini AI workstation and it delivers on the hype: tiny (150 x 150 x 50.5 mm), strikingly designed, high-memory, NVIDIA-based hardware that’s being touted as a must-have for many AI developers — and even a seriously practical tool for executives leading AI deployments. The reviewer ordered two with the copper DAC bundle immediately after seeing it at GTC 2025 and says the Spark’s combination of size, build, and purpose-built I/O make it especially compelling, though this unit is pre-production and has a few early “teething” quirks (notably some display caveats and embargo-related demo constraints). The technical showpiece is networking: DGX Spark ships with NVIDIA ConnectX‑7 NICs providing 200GbE QSFP56 ports (four channels of 56G/50Gbps PAM4) plus a Realtek 10GbE port. Those QSFP56 ports support RDMA and can be linked via copper DACs to stitch multiple GB10 units together for pooled compute and memory — a core part of the GB10 value proposition. Other I/O includes USB‑PD Type‑C power input, three USB‑3 20Gbps Type‑C ports with DisplayPort alt mode, and HDMI; DGX OS bundles the necessary drivers. In short: a tiny, high‑memory, network-centric appliance designed to scale through fast RDMA fabrics — ideal for local development, clustered edge deployments, or compact on‑prem AI nodes.
