Intel is going to include to the quad-core socket LGA-1156 the foremost Intel CPUs, supported on 32nm process expertise: dual-core processors Core i5 as well as Core i3 "Clarkdale". Engineering samples of these processors were shown to the creator in the second quarter of 2009, but only just made attempts to show the overclocking potential of these processors with air cooling. With low-voltage crackdown, carried out by, engineering samples without strain reached a frequency close to 4.00GGts, at a voltage of 0.832V. Later overclocker, leader of the community Lab501, checked the overclocking potential of the sample dual-core Core i5 650 LGA-1156 Dual-Core with air cooling.

Processor Core i5 650 was installed on the Gigabyte motherboard with a chipset P55, cooled cooler Noctua NH-U12P with fan Coolink SWIF 2 120P. This processor has reached the frequency 4.70GGts (25 x 188MGts), i.e. almost 50% higher than its nominal frequency equal to 3.20GGts (24 x 133MHz). CPU voltage was 1.424V. At a frequency 4.70GGts processor worked steadily for 30 minutes while the temperature of its nuclei was 77 ° C and 68 ° C. The ambient temperature was 24 ° C.

Despite the fact that when overclocking used an engineering sample, and therefore, the data can not be considered absolute truth for the final version of the processor, these results are well characterized by the potential of the new architecture. High overclocking potential is a consequence of the use of 32nm process. Issue CPU Core i5 650 will be approximately three months. In addition, the processor in the first quarter of 2010, Intel plans to release Core i5 660/661 (3.33GGts, HTT), Core i5 670 (3.46GGts, HTT), Core i3 540 (3.06GHz, without HTT), Core i3 530 (2.93GGts without HTT), as well as the Pentium G6950 (2.80GGts without HTT).
