First look at the NVIDIA DGX Spark — what the box actually reports (2026)
The NVIDIA DGX Spark reports itself as a 20-core Arm machine (10× Cortex-X925 + 10× Cortex-A725), 121 GiB of unified LPDDR5x memory, a single GB10 Blackwell GPU on CUDA 13, and a 4 TB Samsung NVMe — all in a gold box the size of a thick paperback. This first-look post reads the whole machine back from the command line (lscpu, free -h, nvidia-smi, lspci, lsblk) and shows it doing the one thing no consumer GPU can: holding a 67 GB llama4:scout and a 65 GB gpt-oss:120b model in memory at the same time.
