Intel Core i7-4702HQ
The Intel Core i7-4702HQ is a high-end quad-core processor for laptops. It is based on the Haswell architecture and manufactured in 22nm. 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 2.2 GHz but can dynamically increase clock rates with Turbo Boost up to 2.9 GHz (for 4 active cores), 3.1 GHz (for 2 active cores) and 3.2 GHz (for 1 active core).
Haswell is the successor to the Ivy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm and offer an optimized branch prediction as well as additional execution ports. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.
The performance of the Core i7-4702HQ is slightly above a similarly clocked Ivy Bridge processor due to the architectural improvements. As a result, overall performance is similar to the Ivy Bridge based Core i7-3630QM.
With a TDP of only 37 Watt, the Core i7-4702HQ is specified at the level of mobile dual-core CPUs. Therefore, even smaller laptops can use the Core i7.
