As usual our power-consumption test. This time you have to consider, all tests were done with C-States enabled (CS en) or C-States disabled (CS dis). The later prevents the CPU from going into "deep-sleep" which does increase the power-consumption especially in idle power. When under-voltaged about 20% the i5 750 is superb. This is the first time a Core i series chip can beat the previous generation, while we have to note, we did not test that.
