Intel Core i3 3120M

older Released September, 2012

2.5 GHz
Dual core

0 Out of 10 CPUBoss Score		The Intel Core i3 3120M is a dual core processor based on the Ivy Bridge series. The two cores sport a base speed of 2.5GHz, but Turbo Boost is not available. Through Hyperthreading, the two cores can support up to four simultaneous threads, leading to a better CPU utilisation. Much like all Ivy Bridge processors, this one includes 3D transistors, which improve energy efficiency, when compared to similarly clocked Sandy Bridge processors. Also like all Ivy Bridge processors, the 3120M includes an Intel HD Graphics 4000 and is also best suited for laptops, where even smaller ones can use it due to its smaller architecture.
