| Note | Micro-benchmark study of nvidia-smi power readings on over 70 NVIDIA GPUs from every generation since Fermi. States that nvidia-smi uses NVML, that on A100 and H100 GPUs only 25% of runtime is sampled for power, and that the reading's error is about ±5% rather than the ±5 W NVIDIA claims. |
