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 fact that the near three year old Intel i7-3960X still tops the speed charts reflects just how little competition there is in the CPU market. Intel have dominated for so long that there is simply no economic incentive to push the speed boundaries at anywhere nearly the pace of improvement we saw in previous years. The i7-3960X has 6 cores and 12 threads which is two cores more than the vast majority of Intel's other top end processors. The extra two cores explain why the 3960X still performs so well compared to the majority of the 3960X's newer siblings. This processor will offer little more than a far cheaper i3 to regular desktop users but for server orientated workloads it is still one of the best processors available. [Mar '14 CPUPro]
