Good evening, I purchased a Jetson Orin NX 16GB from seed studio.
I use the card to make inference using Yolo.
With a Jetson Orin Nano (less powerful) I get a real time result of 60 milliseconds per frame, while using the Jetson Orin NX (more powerful) I get a real time result of 100 milliseconds per frame
(same camera connected and same program)
Using jetson-stats I can see the following statistics:
- 95%/100% GPU usage
- 8GB RAM used on 16GB
- 4 CPU cores are turned off (before, after and during program execution)
jetpack: 5.1.1 for both cards.
The libraries I use are the same for both cards:
- opencv 4.5.4
(the most significant)
I wanted to ask for your help to understand first of all why there are 4 out of 8 CPU cores constantly turned off and if they can be activated in some way.
And above all why a card with approximately double the power compared to the Orin Nano makes an inference at double the milliseconds per frame compared to our Orin Nano (following the factory statistics I should find a lower result, therefore much less than 60 milliseconds per frame with the Orin NX).
Are there drivers to install that are not present in the jetpack installation?
What should I do/check/change/install?
I really don’t know how to explain myself and what to do.
I hope someone can help me, I really need it, sorry if it seems trivial, but I’m a beginner.
Thanks a lot in advance to anyone who will help me!
