Intel core i7-3612qm vs intel core i5 2450m

As a result, overall performance is similar to the Sandy Bridge Core i7-2820QM.В Altough the 3612QM has a higher model number than the 3610QM, it offers slower clock rates and therefore performs worse. The performanceВ of the Core i7-3612QM is slightly above a similarly clocked Sandy Bridge processor due to the architectural improvements. Other new features are integrated PCI Express 3.0 and DDR3(L)-1600 support. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistorsВ forВ increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Ivy Bridge is an enhanced d ie shrinkВ of the Sandy Bridge architecture with improvements on both GPU and CPU performance. Both dont support vPro, but otherwise all Ivy Bridge features like AES or VT-x are useable. The BGA version (that is directly soldered to the mainboard) supports VT-d virtualization, whereas the rPGA version does not. Compared to the other quad core CPU, the 3612QM is specified at a TDP of only 35 Watt (similar to the dual-core CPUs).

Each core offers a base speed of 2.1 GHz but can dynamically increase clock rates with Turbo Boost up to 2.8 GHz (for 4 active cores), 3.0 GHz (for 2 active cores) and 3.1 GHz (for 1 active core). Due to Hyperthreading, the four cores can handle up to eight threads in parallel leading to better utilization of the CPU. It is the fastest mobile processor rated at 35 Watt (at the time of announcement in mid 2012). The Intel Core i7-3612QMВ is a fast quad-core processor for laptops based on the Ivy Bridge architecture.
