![]() On a theoretical full load, the i3-2100T and i5-2400S used 12W and 14W less respectively than its similarly-named counterparts. While some users work their systems hard, other machines are often left idling or used for mundane tasks like watching video or surfing the web for hours on end.Īt idle and during video playback using discrete graphics, the i3-2100T, undervolted i5-2400, and i5-2400S were a tad more frugal than i3-2100 and i5-2400, but the difference was just one watt. Our first test is low load system power consumption, at idle and during video playback. Higher voltages don’t necessarily equate to higher power consumption, but in many cases there is a correlation. Different motherboard models do not apply the exact same core voltage either. The same processor often run at slightly different operating voltages whichĬan affect energy efficiency. Of the processors tested today as sort of a disclaimer. To figure out for yourself if you really want to.īefore we jump into our test results, please note the operating voltages We won’t go through the math it’s easy enough ![]() We extrapolate the DC power output from the measured AC power This data is enough to give us a very good estimate of DC demand in our
