CPU/GPU power consumption in idle mode

[andy.yu1]

Hi Nvidia experts,

We checked the document Supported Modes and Power Efficiency, but it didn’t provide power consumption in idle mode.

mode_15W:
In system idle, we noticed that the GPU consumes 2800mW, the CPU consumes 400w.
Is this within the specifications of the Jetson AGX Orin?
Could you please help to provide CPU/GPU power consumption information?

Best regards,
Andy

Hi andy.yu1,

Are you using the devkit or custom board for AGX Orin?
What’s your Jetpack version in use?

Could you try to run any cuda-samples to get GPU working and check the power usage?

Hi KevinFFF,

We are using custom board for AGX Orin.
Version: nvidia-l4t-core 35.4.1-20230801124926
Cuda version:12.2

Result of cuda_sample matrixMulCUBLAS:

The GPU works fine, but our question is about GPU power consumption in idle mode.
Is there a standard range for CPU/GPU power consumption in idle mode?

@andy.yu1

Is there a standard range for CPU/GPU power consumption in idle mode?

You can compare the result with the AGX Orin devkit.
