Intel Core i3-3120M

Intel 3120M

The Intel Core i3-3120M is a dual-core processor for laptops based on the Ivy Bridge architecture. Due to Hyperthreading, the two cores can handle up to four threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.5 GHz, Turbo Boost is not supported. As its Sandy-Bridge-based predecessors, it offers a 3 MB L3-Cache.

Ivy Bridge is an enhanced die shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Other new features are integrated PCI Express 3.0 and  DDR3(L)-1600 support.

The performance of the Core i3-3120M is slightly above a similarly clocked Sandy Bridge processor due to the architectural improvements. As a result, overall performance is about 5 - 10 % faster compared to the old i3-2370M. Thanks to their Turbo Boost, Core-i5-models like the i5-3210M are significantly faster (10 - 25 %).

The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1100 MHz with Turbo Boost. Therefore, the performance is slightly below an AMD Radeon HD 6620G.

Just like most other Ivy Bridge dual-cores, the i3-3120M is rated at a TDP of 35 W. Therefore, even smaller laptops can use the Core i3.
