Intel Core i7-3612QM vs Intel Core i7-3520M

Intel Core i7-3612QM

► remove from comparison Intel 3612QM

The Intel Core i7-3612QM is a fast quad-core processor for laptops based on the Ivy Bridge architecture. It is the fastest mobile processor rated at 35 Watt (at the time of announcement in mid 2012). Due to Hyperthreading, the four cores can handle up to eight threads in parallel leading to better utilization of the CPU. 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). Compared to the other quad core CPU, the 3612QM is specified at a TDP of only 35 Watt (similar to the dual-core CPUs). The BGA version (that is directly soldered to the mainboard) supports VT-d virtualization, whereas the rPGA version does not. Both dont support vPro, but otherwise all Ivy Bridge features like AES or VT-x are useable.

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 i7-3612QM is slightly above a similarly clocked Sandy Bridge processor due to the architectural improvements. As a result, overall performance is similar to the Sandy Bridge Core i7-2820QM. Altough the 3612QM has a higher model number than the 3610QM, it offers slower clock rates and therefore performs worse. However, the 3610QM is specified at a much higher TDP of 45 Watt.

The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1100 MHz with Turbo Boost, making it one of the faster variants.

With a TDP of only 35 Watt, the Core i7-3612QM is the first quad-core CPU from Intel that is specified at the level of the dual-core mobile CPUs. Therefore, even smaller laptops can use the Core i7.

Intel Core i7-3520M

► remove from comparison Intel 3520M

The Intel Core i7-3520M is the fastest dual-core processor for laptops based on the Ivy Bridge architecture at the time of introduction in Q2 2012. 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 2.9 GHz but can dynamically increase clock rates with Turbo Boost up to 3.4 GHz (for 2 active cores) and 3.6 GHz (for 1 active core). As its Sandy-Bridge-based predecessor Core i7-2640M, it offers a 4 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 i7-3520M is slightly above a similarly clocked Sandy Bridge processor due to the architectural improvements. As a result, overall performance is about 5 - 10 % above the old i7-2640M (see benchmarks below).

The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1250 MHz with Turbo Boost, making it one of the fastest variants.

Just like most other Ivy Bridge dual-cores, the i7-3520M is rated at a TDP of 35 W. Therefore, even smaller laptops can use the Core i7.
