Intel Core i7-3720QM vs Intel Core i7-3635QM

Intel Core i7-3720QM

► remove Intel 3720QM

The Intel Core i7-3720QM is a fast high-end quad-core processor for laptops based on the Ivy Bridge architecture. 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 2.6 GHz but can dynamically increase clock rates with Turbo Boost up to 3.4 GHz (for 4 active cores), 3.5 GHz (for 2 active cores) and 3.6 GHz (for 1 active core).

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 i7-3720QM is slightly above a similarly clocked Sandy Bridge processor due to slight architectural improvements. As a result, overall performance is higher than the former fastest model, the Core i7-2920XM.

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 faster variants.

As with most quad-core Ivy Bridge models, the Core i7-3720QM is specified at a TDP of 45 Watts including graphics card and memory controller. Therefore, the CPU is well-suited for laptops 15-inches or greater.

Intel Core i7-3635QM

► remove Intel 3635QM

The Intel Core i7-3635QM is a fast quad-core processor for laptops based on the Ivy Bridge architecture. 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 2.4 GHz but can dynamically increase clock rates with Turbo Boost up to 3.2 GHz (for 4 active cores), 3.3 GHz (for 2 active cores) and 3.4 GHz (for 1 active core). In contrast to the 3630QM, the 3635QM has a different package (BGA) and a slightly higher GPU clock.

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 i7-3635QM is slightly above a similarly clocked Sandy Bridge processor due to slight architectural improvements. As a result, overall performance is similar to the fastest Sandy Bridge model, the Core i7-2960XM.

The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1200 MHz with Turbo Boost, making it one of the faster variants.

As with most quad-core Ivy Bridge models, the Core i7-3635QM is specified at a TDP of 45 Watts including graphics card and memory controller. Therefore, the CPU is well-suited for laptops 15-inches or greater.
