Power Consumption of Genio 520/720-EVK

The following is the power consumption data of Suspend and Idle, and we will provide the measurement SOP.

Table 1. Low Power Data of G720-EVK

	Current (mA)	Power (mW)
Suspend	46.65	195.93
Idle (cluster-off state)	138.95	583.59

Table 2. Low Power Data of G520-EVK

	Current (mA)	Power (mW)
Suspend	45.01	189.04
Idle (cluster-off state)	136.75	574.35

Suspend

• Step 1 : Power on DUT

• Step 2 : Wait for the system to initialize, about 1-2 minutes

• Step 3 : Set the system to suspend mode.

  echo mem > /sys/power/state
  

• Step 4 : The console cannot input commands, which means it enters suspend

• Step 5 : Wait for 1 minute and start measuring

Idle

• Step 1 : Power on DUT

• Step 2 : Wait for the system to initialize, about 1-2 minutes

• Step 3 : Turn off some extra services

  systemctl stop NetworkManager.service
  echo off > /sys/class/drm/card0-DSI-1/status
  

• Step 4 : Wait for 1 minute and start measuring
