NVIDIA Jetson Orin Nano - Performance Tuning by Tuning Power
NVIDIA Jetson Orin Nano RidgeRun documentation is currently under development. |
Max-Q and Max-P Power Efficiency
The Orin supports three different power modes known as 7W and 15. For each mode, several configurations with various CPU and GPU frequencies, and a number of cores online are possible.
Mode ID | 0 | 1 | 2 | 3 |
---|---|---|---|---|
Power Budget | EDP | 7W | 15W | 50W |
Online CPU | 12 | 3 | 6 | |
CPU Max Frequency (MHz) | 2147.48 | 1.1136 | 1.728 | 1.4976 |
GPU Max Frecuency (MHz) | 2147.48 | 420.75 | 624.75 | 828.75 |
DLA Max Frequency (MHz) | 2147.48 | 1369.6 | 750 | 1369.6 |
PVA Cores | 2 | 1 | 1 | 1 |
PVA Max Frequency (MHz) | 1088 | 307.2 | 512 | 704 |
The default mode is id 0. EDP represents the limits and therefore has no power budget.
A utility is provided to change the board operations between these modes. In order to change the current operation mode use the command:
ID=2 sudo /usr/sbin/nvpmodel -m $ID
The mode persists across power cycles and won't change unless nvpmodel is called again.
NOTE: You can use the modes ID from the table above to change the board operations. |
In order to find the current mode use:
sudo /usr/sbin/nvpmodel -q
Extra Definitions can be added in a file located in:
/etc/nvpmodel/nvpmodel_t194.conf
