Power Consumption
Ivy Bridge's system power consumption is impressive. The Core i7-3770K consumed 11% less power than the i7-2600K in spite of carrying a faster clock speed and performing overall better. The idle consumption results remained much the same, as the Core i7-3770K configuration used 75 watts at idle compared to the 76 watts of the i7-2600K. Looking at previous generation chips, you see the downward pattern against the 98 watts of the Core i7-3820 and 100 watts of the FX-8150.
Under load the Core i7-3770K configuration consumed 14% less power than the i7-3820, 37% less than the Phenom II X6 1100T, and 42% less power than the FX-8150.
