Yesterday, Intel introduced Ivy Bridge processors, which were the first products produced on 22 nm technology.  There were no significant changes in compraison with the  past generation architecture (Sandy Bridge) . Nevertheless, overclockers hoped for  more impressive overclocking potential, which will compensate for the slight difference in performance in terms  MHz.
Shortly before the official presentation of Ivy Bridge, appeared a disturbing message that Intel not only returned to their previous TDP level, which is characteristic for the 32-nm products Sandy Bridge, but has difficulty with 22 nm technology.
Journalists paid much attention to overclocking potential, based on what was produced the first overclocking statistics of Core i7-3770K.
The most typical result was 4.6-4.7 GHz with a small increase in voltage. Â An effective cooling system (preferably liquid) allows to overclock processors at frequencies up to 5.0 GHz, and some good models are able to work a 5.5 GHz with air cooling. Â However, for everyday use are optimal 4.4-4.7 GHz (air) or 5 GHz (water).
AnandTech conducted detailed studies of energy dependence and CPU core voltage temperature. Â Temperature measurements were made using the tool PovRay, power consumption was measured by OCCT.
The dependence of the maximum achievable frequency on voltage:
It should be noted that Ivy Bridge  processors does not like to increase the voltage and power settings, it heated to a temperature above 90 ° C, which must be considered when overclocking. Related Products :
