NVIDIA DGX Spark
Consumer GPU · Blackwell · GB10
The DGX Spark is NVIDIA's compact desktop AI computer, built around the GB10 chip. It pairs a Blackwell GPU with an Arm CPU and 128GB of unified LPDDR5x memory.
The DGX Spark's unified memory is signficantly slower than most modern discrete GPUs' HBM. It also has lower processing power than most data centre GPUs and the top gaming GPUs. See our Rent vs Buy article for the DGX Spark's prefill/decode performance on Qwen3.8-27B and Qwen3.8-Flash-Next.
It is currently only available for short-term rental from peer-to-peer marketplaces such as Vast.ai.

Peak theoretical performance
Performance figures assume no sparsity; in cases where only sparse performance figures are published by the manufacturer, these are halved to give approximate dense performance.
