Nvidia DGX Spark Draws Unexpected Idle Power
7.1
Relevance Score
Nvidia's DGX Spark, reviewed by Tom's Hardware, proved compact and capable for LLM inference and generative image/video workflows with 128GB RAM, a 20-core Arm CPU, and Blackwell GPU. However, testers found it consumed about 37W at idle despite a 3nm-class GB10 SoC and mobile-grade power management; reviewers identified the cause and an easy fix to reduce idle draw.
