Inquiry regarding power consumption issues of Jetson AGX Orin Industrial

Robotics & Edge Computing Jetson Systems Jetson AGX Orin

We recently used the Jetson AGX Orin Industrial and found that its CPU power consumption during stress testing was very low, approximately only 7W. I would like to inquire if this is within expectations?

The device is set to maximum power mode, and sudo jetson_clocks is simultaneously enabled. Then, stress-ng is used to perform stress testing on all CPU cores. With the command stress-ng --cpu 0 --cpu-method matrixprod --timeout 120s --metrics-brief, jtop shows that the power consumption is only around 10W

Thanks for the detailed setup information. To help determine if the 7-10W reading is expected, I need a few clarifications:

  1. Expected baseline: According to the official Jetson documentation, the expected maximum CPU power consumption during stress testing on AGX Orin is 60W (64GB) or 40W (32GB). Your reading of ~10W is significantly lower. Can you confirm which variant you’re using (64GB or 32GB)?

  2. CPU frequency: What CPU frequency is reported by jtop during the stress test? If the cores are running at reduced frequencies despite jetson_clocks being enabled, that could explain the lower power draw.

  3. Performance impact: Are you observing any performance degradation or thermal throttling during the test? Check the thermal alert status in jtop.

  4. Consistency: Is this low power reading consistent across multiple test runs, or was it a one-time observation?

These details will help determine whether this is normal behavior for your configuration or indicates a measurement/configuration issue.

Can you please try the test linked in this comment? The creator of that thread also saw 10W on CPU-CV rail.

Please check the result of tegrastats first.

  1. We are using Jetson AGX Orin Industrial, which is slightly lower than ORIN 64G
  2. We use tegrastats to record the CPU status, with a frequency of 2.0GHz
  3. The temperature is normal, far below the threshold
  4. Multiple tests were conducted, and the results were consistent across different machines

We will verify according to the link you provided, and if there are any issues, I will provide feedback

Hello, we have noticed that the CPU power is relatively low on both the ORIN module and Jetson AGX Orin Industrial, and it fails to reach the threshold. Could you kindly provide a testing method that can fully utilize the CPU power? Also, are there any risks associated with the power not reaching the threshold in practical use
