Max-Q and Max-P Power Efficiency
The Orin supports three different power modes known as 15W, 30W, and 50W. 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 | 15W | 30W | 50W |
| Online CPU | 12 | 4 | 8 | 12 |
| 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
