NVIDIA DGX Spark supports 8-unit clusters: unified memory up to 1TB with 128GB versions, RTX PRO 6000 Blackwell related tasks up to 40% faster

NVIDIA announced at GTC 2026 in Berlin that DGX Spark can now be manually configured into clusters of up to 8 units, double the previous 4-unit limit; eight 128GB units deliver up to 1TB of unified memory. NVIDIA worked with the llama.cpp and vLLM open-source communities to optimize AI inference, yielding up to 40% speedups on RTX PRO 6000 Blackwell and up to 30% and 20% on DGX Spark and DGX Station; the 64GB version costs $4,999 and goes on sale via partners starting October 23, with the Sync Model Launcher tool arriving later this month. This matters because DGX Spark is NVIDIA's developer-focused local AI workstation, and doubled cluster capacity plus inference gains let individuals and small teams run large models locally at lower cost, reinforcing NVIDIA's position in local AI.
