Super processor. I could my volts to 4.5 GHz / 1.2, 4.7 / 1.31 volts and overclock even volts to 4.8 GHz / 1.37. I did not want to go higher. Was Overclocket on ASRock Z77 Extreme4 board. All values were 100% utilization of all he geteste cores under Prime95 and were stable. Now we come to the detriment: The temperatures were at full capacity at 4.5 GHz (average 62c / 72c max), 4.7 GHz (76c / 86c max) and 4.8 GHz (88c / max 103c). Was cooled with an Intel rts 2011 Water cooling. The core temperature was very high, but the radiator water cooling was only lukewarm. Reason: The very small 22nm production can not give gutgenug on cooling the heat because the area is smaller than that of Sandy Bridge. I think the Temeraturen would have been no better if they had even used a high-end water cooling because the heat is very poorly managed directly from the small 3D architecture. Is just an Ivy Bridge disease. Even in the standard clock the CPU is very warm idle 37c and 64c at full load. Who but the temps do not care about how I can access calm. Intel is a maximum Termperaturgerenze 105c then comes the throttling. Definitely a Kaufempehlung.
Advantages: performance, fuel consumption, overclocking, Disadvantage: poor continuation of the heat from the core to cool
