Power consumption increasing when adding stress on AGX Orin 32GB and AGX Xavier 32GB

[jiangtao.zhao]

Hi guys, anyone who had got the data of power consumption increasing when adding stress on CPU and GPU of AGX_Orin_32GB and AGX_Xavier_32GB as below:

I need to check my result right or not. Thanks a lot.

hello jiangtao.zhao,

you should check with real use-case instead of GPU/CPU stress power consumption.
besides, you may refer to Topic 251265 for the description/linkage of Jetson Power Estimator tool.

Hi Jerry, Jetson Power Estimator great help for me. Thank you very much.

I have another question:

Are there any other parameters besides the above four that can adjust the operation of matrixMul? The power consumption increasing about ~20W when running at AGX_Xavier_32GB, but the power consumption only increasing about~10W when running at AGX Orin_32GB.

[JerryChang]

it’s due to Xavier and Orin they’re having different performance.
may I have more details, what’s the real use-case to compare power consumption between them?

Actually, the purpose is to define a reasonable stress level for the GPU of AGX_Orin_32GB to confirm the thermal situation of our product. On the PowerEstimator, for maximum GPU stress, the power increasing of the GPU is approximately 18.4W, while the power consumption has increased about10W by using matrixMul. So, we would like to know if matrixMul can have other parameters to adjust the stress level , Or any other stress tools be available? Thanks.
