DGX Spark

AI workstation, GB10 superchip

Short answer. The DGX Spark is a compact NVIDIA AI workstation built around the GB10 superchip (128 GB unified LPDDR5X at 273 GB/s, 1 PFLOP FP4). Its NVIDIA list price is $4,699 excl. tax (€5,083 to €7,000 excl. VAT at European resellers as of October 2026, or €8,400 incl. VAT). It runs models up to 200 billion quantised parameters locally on one node (up to 405 billion across two QSFP-linked units) with llama.cpp or vLLM.

What the machine runs

Models up to 200 billion parameters quantised on a single node. With two nodes directly connected by a QSFP cable, NVIDIA claims up to 405 billion parameters (Project DIGITS announcement, January 2025); beyond that, the ConnectX-7 NICs go through an Ethernet switch, up to four units and 700 billion parameters according to the NVIDIA datasheet re-read on 2 September 2026. Recommended runtime: llama.cpp or vLLM locally.

Positioning

DGX Spark: NVIDIA's compact AI workstation on the GB10 superchip, 128 GB of unified memory, quantised models up to 200 billion parameters on one node.

Manufacturers

NVIDIA offers the DGX Spark through its partners, including Acer, ASUS, Dell, Gigabyte, HP, Lenovo and MSI.

GPUDirect Storage

On platforms fitted with ConnectX cards, GPUDirect Storage technology establishes a direct path between NVMe or NVMe over Fabric storage and GPU memory, bypassing the CPU buffer. Compatible storage arrays, such as NetApp, VAST, DDN or WEKA, feed training and large-scale RAG at full speed.

Support

Open stack, maintained by its communities. Optional NVIDIA AI Enterprise (NIM, NeMo, Triton) with a service-level agreement, licensed per GPU.
