The CPU core voltage (V CORE) is the power supply voltage supplied to the processing cores of CPU (which is a digital circuit), GPU, or any other device with a processing core. The amount of power a CPU uses, and thus the amount of heat it dissipates, is the product of this voltage and the current it draws. In modern CPUs, which are CMOS ...
In many applications, the CPU and other components are idle much of the time, so idle power contributes significantly to overall system power usage. When the CPU uses power management features to reduce energy use, other components, such as the motherboard and chipset, take up a larger proportion of the computer's energy.
The high temperature on the chip, if not controlled, can damage or even burn the chip. The chip high temperature also has impacts on performance and reliability. [10] [11] High chip temperature causes more leakage power consumption, higher interconnect resistance and slower speed of transistors. [10]

The average CPU power (ACP) is the power consumption of central processing units, especially server processors, under "average" daily usage as defined by Advanced Micro Devices (AMD) for use in its line of processors based on the K10 microarchitecture (Opteron 8300 and 2300 series processors).
A specified period of time that will be allowed to elapse in a system before a specified event is to take place, unless another specified event occurs first; in either case, the period is terminated when either event takes place. Note: A timeout condition can be canceled by the receipt of an appropriate time-out cancellation signal.
Here, a processor may be a (single-core) CPU or one core in a multi-core CPU. Example: A software application executed on a four-core processor creates four Unix processes. If each process is able to execute on a separate processor core, computation proceeds on four processor cores simultaneously. The total CPU time would be, ideally, four ...
