The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

The Intel Core i7-4700HQ is a fourth generation top-end mobile Haswell CPU. With a base clock of 2.4 GHz and a maximum turbo clock of 3.4 GHz. The 4700HQ has a maximum TDP of 47 Watts and is equipped with 4 cores and 8 threads so it's equally at ease with both single-core and multi-core workloads. Thanks to the 4700HQs relatively high turbo clock speed and its relatively new architecture it achieved an effective speed of 83.3 which is staggering for a mobile processor and actually only 15% below the average of the top nine group leaders which include both desktop and server CPUs. This mobile CPU will give older workstations a run for their money. [Oct '14 CPUPro]
