Measuring maximum power consumption

Hello,
as part of power consumption for jetson AGX Orin i’m trying to implement SW tests which will consume maximum power from the jetson.
I configured my own power mode using nvpmodel that contains maximum GPU performance.
I’m running AI inference on TRT and i see 99% GPU load and the VDD_GPU_SOC is near 30W.
i tried run cuda code in parallel to the inference and the power still near 30 W.
I’m using Jetson Power GUI for checking the power.
Does it mean that the GPU is limited to 30W maximum?
If yes, is there a list of maximum power for each “device” in jetson?

Thanks

Hi,
Here are some suggestions for the common issues:

1. Performance

Please run the below command before benchmarking deep learning use case:

$ sudo nvpmodel -m 0
$ sudo jetson_clocks

2. Installation

Installation guide of deep learning frameworks on Jetson:

3. Tutorial

Startup deep learning tutorial:

4. Report issue

If these suggestions don’t help and you want to report an issue to us, please attach the model, command/step, and the customized app (if any) with us to reproduce locally.

Thanks!

Thanks for the respond.
Maybe i’ll try another more generic approach for my question.
CPU power:
What maximum value should i expect at VDD_CPU_CV with maximum stress test?
I ran stress application (that was downloaded according to your answer from Jetson/L4T/TRT Customized Example - eLinux.org) and the maximum power i received was 10 W.
So, i could think that the maximum power that the CPU can consume is 10W.
But when i ran my benchmark, i got maximum value of around 12 W at VDD_CPU_CV.
How i should know what is the maximum value of the power that i can get?
By the way i ran both benchmarks on all 12 cores (i’m using AGX Orin industrial board).

GPU power:
If the GPU works for 10 minutes at GPU load 99% (at MAXN power mode with jetson_clocks enabled).
What value should I expect at VDD_GPU_SOC?
I succeed to go up to 30W.

Hi, please refer to below info in Orin module data sheet.

JAOi Maximum Module Power: Up to 75W
JAO 64GB Maximum Module Power: Up to 60W
JAO 32GB Maximum Module Power: Up to 40W

Thanks.
My goal is to bring the jetson to maximum power consumption for power analysis.
And for now i can’t reach even 60 W in total.
So i’m trying to understand how to reach it by stress test for specific HW (CPU, GPU, memory).
