What we know

Online discussions, including comments on Hacker News and other forums, suggest that encrypted firmware on Nvidia DGX Spark hardware reduces inference speed to about 35% of normal performance when running on Linux. These reports come from user observations rather than official benchmarks or statements from Nvidia.

Why it matters

If encrypted firmware significantly slows inference on Linux, this could impact the performance and efficiency of Nvidia DGX Spark systems for users relying on Linux environments. Such a reduction in speed would affect workloads that depend on fast inference, potentially limiting the hardware’s appeal for AI and machine learning applications on Linux. However, these claims have not been confirmed by independent testing or official sources.

What is still unknown

No independent tests have verified the accuracy of the reported performance drop or assessed its impact on different workloads. Details about which Linux distributions or driver versions are affected remain unclear. Nvidia has not publicly addressed these claims, and there is no information on whether firmware updates or patches might resolve the issue. Supported languages, broader availability, and official performance benchmarks have not been disclosed.
