Intel Core i7-4800MQ
The Intel Core i7-4800MQ is a high-end quad-core processor for laptops which has been launched in Q2/2013. 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 2.7 GHz but can dynamically increase clock rates with Turbo Boost up to 3.5 GHz (for 4 active cores), 3.6 GHz (for 2 active cores) and 3.7 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, improving the performance per clock by almost 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.
Due to these changes, the performance has been improved slightly compared to Ivy Bridge. Therefore, the 4800MQ is about 10 % faster than the former i7-3740QM.
The i7-4800MQ is rated at a TDP of 47 W including graphics card, memory controller and VRMs. Therefore, the CPU is only suited for laptops 15-inches or greater.
