NVIDIA's Desk-Size Supercomputer Puts Big AI Models Within Arm's Reach
Techstrong.ai, Wednesday, October 15th, 2025
NVIDIA has begun shipping DGX Spark, a book-sized AI supercomputer that brings a full NVIDIA software stack and a robust amount of memory to a desk or lab bench, at a list price of $3,999.
DGX Spark centers on the GB10 Grace Blackwell Superchip, which pairs a 20-core Arm CPU with a Blackwell-class GPU and ties them together with coherent memory. The headline spec is 128GB of unified LPDDR5x shared between CPU and GPU. That figure matters more than raw TOPS for many practitioners, because it determines which models fit entirely on the device.
