List of CPU Power Dissipation Figures - Early CPUs

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:

  • EDVAC, 50 kW average
  • ORDVAC, 35 kW average
  • UNIVAC I, 124.5 kW average

Famous quotes containing the word early:

    “I do not know that I meet, in any of my Walks, Objects which move both my Spleen and Laughter so effectually, as those Young Fellows ... who rise early for no other Purpose but to publish their Laziness.”
    —Richard Steele (1672–1729)
