Encyclopedia > CPU power dissipation

CPUs (Central processing units) in their various incarnations consume some amount of electric power. This power is dissipated both by the action of the switching devices contained in the CPU (such as transistors or vacuum tubes) as well as energy lost in the form of heat due to the resistivity of the electrical circuits. This is a major consideration in the design of CPUs and the computers they are used in. “CPU” redirects here. ... For delivered electrical power, see Electrical power industry. ... Assorted discrete transistors A transistor is a semiconductor device, commonly used as an amplifier or an electrically controlled switch. ... Structure of a vacuum tube diode Structure of a vacuum tube triode In electronics, a vacuum tube, electron tube, or (outside North America) thermionic valve or just valve, is a device used to amplify, switch or modify a signal by controlling the movement of electrons in an evacuated space. ... For other uses, see Heat (disambiguation) In physics, heat, symbolized by Q, is energy transferred from one body or system to another due to a difference in temperature. ... Electrical resistivity (also known as specific electrical resistance) is a measure of how strongly a material opposes the flow of electric current. ...


Some implementations of CPUs use very little power. For example, the CPUs in mobile phones and pacemakers often use just a few microwatts. On the other hand, CPUs in general purpose microcomputers dissipate significantly more power because of their higher complexity and speed. These microelectronic CPUs may consume power in the order of several watts. Historically, early CPUs implemented with vacuum tubes consumed power in the order of many kilowatts (103 watts). “CPU” redirects here. ... A pacemaker, scale in centimeters A pacemaker (or artificial pacemaker, so as not to be confused with the hearts natural pacemaker) is a medical device which uses electrical impulses, delivered by electrodes contacting the heart muscles, to regulate the beating of the heart. ... For other uses, see Watt (disambiguation). ...

CPUs for desktop computers typically use more power than any other component inside the computer, except perhaps recent technology video cards which contain special purpose CPUs themselves. The steady trend in CPU power supplies over the past decade has been towards using lower voltages and having considerably higher currents. While energy-saving features have been instituted in PCs for when they are idle, the overall consumption of today's high-drain CPUs is considerable. This is in strong contrast with the much lower energy consumption of CPUs designed for low-power environments. One such CPU, the Intel XScale, can run at 600 MHz with only half a watt of power, whereas x86 PC processors from Intel in the same performance bracket consume roughly eighty times as much energy. International safety symbol Caution, risk of electric shock (ISO 3864), colloquially known as high voltage symbol. ... The XScale, a microprocessor core, is Intels implementation of the 5th generation of the ARM architecture, and consists of several distinct families: IXP, IXC, IOP and PXA (see more below). ... MegaHertz (MHz) is the name given to one million (106) Hertz, a measure of frequency. ... x86 or 80x86 is the generic name of a microprocessor architecture first developed and manufactured by Intel. ...


Processor manufacturers usually release two power consumption numbers for a CPU, the typical thermal power, which is measured under normal load, and the maximum thermal power, which is measured under a worst-case set of instructions. For example, the Pentium 4 2.8 GHz has 68.4 W typical thermal power and 85 W maximum thermal power. When the CPU is idle, it will draw far less than the typical thermal power.


There are some engineering reasons for this pattern.

  • Performing at higher speed always requires higher power. Reducing processor speed when possible saves power.
  • New features generally require more transistors, each of which uses power. Turning unused areas off saves power.
  • As a processor model's design matures, smaller transistors, lower-voltage structures, and design experience reduce power consumption.

Note that these figures include power dissipation due to energy lost by the computer's power supply and some minor peripherals.

Central processing unit - Wikipedia, the free encyclopedia (7009 words)
CPUs provide the fundamental digital computer trait of programmability, and are one of the necessary components found in computers of any era, along with primary storage and input/output facilities.
A CPU that is manufactured using integrated circuits is known as a microprocessor.
This is a very simple view of CPU address space, and many modern designs use much more complex addressing methods like paging in order to locate more memory than their integer range would allow with a flat address space.
CPU power dissipation - Wikipedia, the free encyclopedia (788 words)
This power is dissipated both by the action of the switching devices contained in the CPU (such as transistors or vacuum tubes) as well as energy lost in the form of heat due to the resistivity of the electrical circuits.
The steady trend in CPU power supplies over the past decade has been towards using lower voltages and having considerably higher currents.
Processor manufacturers usually release two power consumption numbers for a CPU, the typical thermal power, which is measured under normal load, and the maximum thermal power, which is measured under a worst-case set of instructions.
