Intel Core i7-4900MQ
The Intel Core i7-4900MQ is an upcoming quad-core processor for laptops and expected to launch 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 2.8 GHz but can dynamically increase clock rates with Turbo Boost up to 3.6 GHz (for 4 active cores), 3.7 GHz (for 2 active cores) and 3.8 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 especially the Hyper-Threading performance. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.
The exact performance of the Core i7-4900MQ is still unknown. Because of the stagnating clock speeds, we expect the cpu to be about 10 % faster than the former i7-3840QM.
The integrated Intel HD Graphics 4600 offers (presumably) 20 Execution Units (EUs) clocked at 400 MHz up to 1300 MHz with Turbo Boost, making it about 20 % faster than the HD 4000.
The i7-4900MQ 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.
