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
mgruner: Please explain this better. I don't understand what and ID of 5 is, and how do I set a power mode? (please remove this box when addressed) |
An 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
