RTX Spark笔记本在Linux接电时GPU锁频致推理性能暴跌
Start here
2026年11月4日，评测报道指出，在搭载Nvidia RTX Spark架构的笔记本（例如微星 Prestige N16 Flip AI Plus）上安装原生Linux系统时，若接通电源，GPU频率会被异常锁死在约780 MHz。受此影响，相关AI推理性能发生大幅滑坡，以运行GPT-OSS-120B模型为例，其推理速度从Windows系统下的65.4 tokens/s骤降至Linux接电环境下的13.9 tokens/s。

When running native Linux on RTX Spark-based laptops (such as the MSI Prestige N16 Flip AI Plus) while connected to AC power, GPU clock speeds are locked at around 780 MHz. This causes GPT-OSS-120B inference speeds to plummet from 65.4 tokens/s on Windows down to 13.9 tokens/s.
