Power and Thermal values on JTOP

[amira31415]

Hi!

I have a question regarding the thermal configuration vs Jtop app of the orin nano.

Jetson Orin Nano 8GB (performance for 25W): In the thermal guide (figure 3-3 and table 3-8), the listed components are as followed: number 1 is the SOC (20.20 W) , number 3 CPU/GPU Mosfet (0.93W) and number 4 CPU/GPU inductor (0.62W).
When I open JTOP and run a stress load of the same power, I received an output saying: total power 22.5W and from it ‘CPU,GPU’: 15.4 W and ‘SOC’: 3.8W (meaning there is a peripheral power of 3.3W).
How do i match the JTOP and thermal guide components names and power? Does the JTOP CPU\GPU+SOC are equivalent to number 1 SOC in thermal guide?
I want to understand in the case of 25W how the power divides between main components.
And another question regarding the fan: The fan power [W] should be included in the peripheral power that was 3.3W? Any estimation regarding its heat consumption ?
Thanks!

Where can I find the total power from JTOP?

VDD_IN - isnt that the total power?

OK, Have reference to below topic.

Thanks

1. So, the power of VDD_IN is power consumption of whole SOM, right? Yes, VDD_IN is Total SOM power. 2) The value of VDD_CPU_GPU_CV is power of CPU and GPU? The VDD_CPU_GPU_CV is a CPU, GPU, CV (ie DLA & PVA) combined power rail. 3) How about VDD_SOC? By the value from Power GUI, it looks like not the whole SOC power, what does it stand for? Yes, it is not whole SOC power. It is a SOC’s core rail which supplies memory subsystem, engines like decoder, encoder, vi, vic, isp …etc. 4) Channel …
