Energy Costs: When Cool'n'Quiet Mode Doesn’t Work
How high do electrical costs go if the Cool’n’Quiet feature can’t be activated? We make the assumption that the computer is left in standby for about 6 hours a day, and calculate the additional electricity costs for the whole year. We used a cost of 19 cents per kilowatt-hour.
The BE processor that had the lowest electrical intake out of all tested models had a cost increase of $3 (1.90 Euros) per year when Cool’n’Quiet mode was not activated. An FX 62 user can expect to pay $15.40 (10 Euros) more per year.
The Phenom processor uses twice as much electricity as others when in Cool’n’Quiet mode, but shows only a small difference in power costs without it. You can expect to pay $6.24 (4.05 Euros) more per year when Cool’n’Quiet mode is not active.
