  2. Processor power dissipation - Wikipedia

    en.wikipedia.org/wiki/Processor_power_dissipation

    Processor manufacturers usually release two power consumption numbers for a CPU: typical thermal power, which is measured under normal load (for instance, AMD's average CPU power) maximum thermal power, which is measured under a worst-case load; For example, the Pentium 4 2.8 GHz has a 68.4 W typical thermal power and 85 W maximum thermal power.

  3. SpeedStep - Wikipedia

    en.wikipedia.org/wiki/SpeedStep

    Running a processor at high clock speeds allows for better performance. However, when the same processor is run at a lower frequency (speed), it generates less heat and consumes less power. In many cases, the core voltage can also be reduced, further reducing power consumption and heat generation. By using SpeedStep, users can select the ...

    1.12×10 36: Estimated computational power of a Matrioshka brain, assuming 1.87×10 26 watt power produced by solar panels and 6 GFLOPS/watt efficiency. [ 21 ] 4×10 48 : Estimated computational power of a Matrioshka brain whose power source is the Sun , the outermost layer operates at 10 kelvins , and the constituent parts operate at or near ...

  5. Performance per watt - Wikipedia

    en.wikipedia.org/wiki/Performance_per_watt

    The power measurement is often the average power used while running the benchmark, but other measures of power usage may be employed (e.g. peak power, idle power). For example, the early UNIVAC I computer performed approximately 0.015 operations per watt-second (performing 1,905 operations per second (OPS), while consuming 125 kW).

  6. Thermal design power - Wikipedia

    en.wikipedia.org/wiki/Thermal_design_power

    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). Intel's thermal design power (TDP), used for ...

  7. Computer performance - Wikipedia

    en.wikipedia.org/wiki/Computer_performance

    In computing, computer performance is the amount of useful work accomplished by a computer system.Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions.

  8. CPU core voltage - Wikipedia

    en.wikipedia.org/wiki/CPU_core_voltage

    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.

  9. Dynamic frequency scaling - Wikipedia

    en.wikipedia.org/wiki/Dynamic_frequency_scaling

    The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the Activity Factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.
