Processor power dissipation

From Wikipedia, the free encyclopedia
This is an old revision of this page, as edited by 72.23.146.88 (talk) at 21:27, 21 November 2008 (→Intel Core 2 Duo & Core 2 Extreme (dual core): added the tdp of the t5200 and t5270 processors). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

CPU power dissipation or Central processing unit power dissipation is the process in which Central processing units (or CPUs) consume electrical energy, and dissipate this energy by both the action of the switching devices contained in the CPU (such as transistors or vacuum tubes) and via the energy lost in the form of heat due to the resistivity of the electrical circuits. Designing CPUs that perform these tasks efficiently without overheating is a major consideration in nearly all CPU manufacturers to date.

Some implementations of CPUs use very little power, for example, the CPUs in mobile phones and artificial pacemakers often use just a few microwatts of electricity. In comparison, 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 tens of watts. Historically, early CPUs implemented with vacuum tubes consumed power in the order of many kilowatts (103 watts).

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. The steady trend in CPU power supplies over the past decade has been towards using lower voltages and having considerably higher currents.[citation needed] 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.

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.

  • For a given device, performing at higher speed always requires higher power. Reducing processor speed when possible saves power. Speed is often measured in IPS instructions per second or floating-point operatings per second FLOPS.
  • New features generally require more transistors, each of which uses power. Turning unused areas off saves power (for instance, see Clock gating).
  • As a processor model's design matures, smaller transistors, lower-voltage structures, and design experience may reduce power consumption.

Early CPUs

Note that these figures include power dissipation due to energy lost by the computer's power supply and some minor peripherals. However, since the CPU component of these early computers easily accounted for most of the computer's power dissipation, they are mentioned here:

Microprocessors

If not stated otherwise, the watts dissipated refers to the peak-value.

Different architectures vary in how many operations they perform per clock cycle, so MHz/W values are not useful for comparing processors using different internal structure (see Megahertz myth). For other measures of energy efficiency in computing, see Performance per watt.

AMD Athlon XP

Around this time, AMD gave their processors a name which indicated the equivalent clock speed when measured against the original 'Thunderbird' core[5]; hence the XP1800+ would, in theory, have offered similar performance to a 'Thunderbird' Athlon at 1800 MHz despite being only 1533 MHz, since it did more per clock cycle.
