It is based on the Haswell architecture and has been launched in Q2/2013. The Intel Core i7-4770K is a high-end quad-core processor for desktops and successor of the i7-3770K. Intel Core i7-4770K ► remove from comparison Therefore, even smaller laptops can use the Core i7. Just like most other Ivy Bridge dual-cores, the i7-3540M is rated at a TDP of 35 W. The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1300 MHz with Turbo Boost, making it one of the fastest variants. As a result, overall performance is about 5 - 10 % above the old i7-2640M. The performance of the Core i7-3540M 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 transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors.

Ivy Bridge is an enhanced d ie shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance.

As its Sandy-Bridge-based predecessor Core i7-2640M, it offers a 4 MB 元-Cache. Each core offers a base speed of 3.0 GHz but can dynamically increase clock rates with Turbo Boost up to 3.5 GHz (for 2 active cores) and 3.7 GHz (for 1 active core). Due to Hyperthreading, the two cores can handle up to four threads in parallel leading to better utilization of the CPU. The Intel Core i7-3540M is the fastest dual-core processor for laptops based on the Ivy Bridge architecture at the time of introduction in Q1 2013. Intel Core i7-3540M ► remove from comparison
