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. 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. 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. 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 :
