Linux installations on Nvidia RTX Spark laptops like the MSI Prestige N16 Flip AI Plus face severe performance throttling. When plugged into wall power, the GPU clock speed drops from over 2 GHz on Windows to roughly 780 MHz on Linux. This reduces inference speed on a 120B parameter model from 65 tokens per second to just 14 tokens per second.
The issue stems from encrypted power management firmware that only Windows can decrypt. Memory allocation is another hurdle, as Linux cannot adjust the default 96GB unified memory split without Windows settings. WSL remains the best compromise for developers needing full GPU boost and Linux tooling.
A permanent fix requires Nvidia to port the platform controller logic to the Linux driver.
