Orin NX vs Xavier NX power consumption difference

[cameron.turner1]

Hi, I have been testing the Orin NX in our products recently and it was pointed out to me the Orin NX appeared to be drawing more power than we expected it to. After asking in Orin NX SE hardware engine and power consumption and being told it is not related to the SE engine, I am still wondering why compared to a Xavier NX with both devices on Jetpack 5.1.2 I was seeing an idle draw of ~4W (as reported by jtop) vs ~6W on the Orin NX. There were no external connections besides a monitor and ethernet cable, both had an NVME drive connected, and both were using nvidia devkit carrier boards.

Has anyone else noticed similar? When running our software we also see differing power draw but since I can’t share it I can’t really use it as a discussion point here.

Hi cameron.turner1,

@cameron.turner1

I am still wondering why compared to a Xavier NX with both devices on Jetpack 5.1.2 I was seeing an idle draw of ~4W (as reported by jtop) vs ~6W on the Orin NX.

First of all, the performance of Orin NX is more powerful than Xavier NX.
They are from different platform. Xavier NX is from T194, Orin NX is from T234.

There were no external connections besides a monitor and ethernet cable, both had an NVME drive connected, and both were using nvidia devkit carrier boards.

In your use case, do you need the monitor connected?

@cameron.turner1

and both were using nvidia devkit carrier boards.

Is Xavier NX using p3509 devkit board and Orin NX using p3768 devkit board?
Or they both using p3509 devkit board?

@cameron.turner1

When running our software we also see differing power draw

What’s the application you are running?
Or can we just discuss the power consumption in idle state?

Please also share the nvpmodel configuration you used.

In your use case, do you need the monitor connected?

Sometimes yes, i was just being objective in my experiment as rendering to the screen can use more compute.

Or they both using p3509 devkit board?

This was a p3518 board for both.

What’s the application you are running?

Internal software we develop that I can’t share on a public forum. For my testing like I said this was just in an idle state.

The power mode would have been mode 3 (20W) for Orin NX and mode 8 (20W 6 core) for Xavier NX.

I think the devkit board should be p3509 as following.

i was just being objective in my experiment as rendering to the screen can use more compute.

For Orin NX, it is about 5.6W with display output connected, and 4.7W w/o display.

As our understanding, Orin NX would have slightly higher power consumption as expected.
You can also create the custom power config to meet the best power efficiency for your use case.
