TH: "We've seen a great number of processors from Intel with impressive overclocking margins, which means that they can be operated at amazingly high clock speeds, often as high as 30-50% above the specified clock rate. However, extreme overclocking increases power consumption, especially if increased processor voltage is required to reach the desired clock speeds (as we saw in our Phenom II Overclock Optimization story).
Today, we look at an Intel Core i7 920 system to find the best speed settings to deliver truly high performance at still acceptable power consumption levels."
