Its full English name is EPU(Energy Processing Unit), which is actually an independent power management chip hidden under the processor interface. Its function is to automatically adjust the CPU voltage and the number of CPU power supply phases according to the CPU workload. Power supply for four phases when the load is low, and for eight phases when the load is high, which can reduce the current loss.
EPU is a microprocessor chip, which is used to monitor power management in real time. By monitoring the CPU voltage in real time, EPU can save CPU power consumption when your computer runs applications with low requirements!
EPU's unique CPU calibration technology can select the best settings from the database according to different CPU models. (ASUS EPU technology can optimize the power management of all Intel CPUs on the market at present. )
Using ASUS AI Gear3 technology, the system performance can be automatically adjusted according to different situations. Technically, EPU is a programmable digital interface specification, including the design of voltage, current, thermal energy and computer phase. It can display the voltage, current, temperature and power consumption of CPU in real time.
Understanding EPU from another angle is more like a highly sensitive sensor. After the sensor detects the current (load) of CPU, it calls the targeted optimization program according to the CPU type in the database.
