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 5930K is Intel's new middle tier Haswell-E prosumer CPU. This model has base/turbo clocks of 3.5/3.7 GHz and sports 6 physical cores with 12 hyperthreads. The 5930K offers enormous processing throughput but like its Haswell-E siblings it lacks in single and dual-core speed. Comparing the 5930K and 4790K shows that the 4790K offers nearly 20% more single and dual core throughput and is priced nearly 40% lower than the 5930K. The 5930K does win hands down on multi-core workloads but these are not generally relevant to consumers. Finally since the Haswell-E architecture is coupled with the X99 chipset it requires far more expensive DDR4 RAM with offers little upside over DDR3. [Sep '14 CPUPro]

Processor Rankings (Price vs Performance) August 2017 CPU Rankings.

Welcome to our desktop CPU comparison. We calculate effective speed which measures real world performance for typical consumers. Effective speed is adjusted by price to yield a value for money rating which is geared towards gamers. Calculated values don't always paint the whole picture so we check them against hundreds of individual user ratings. The customizable table below combines these factors and more to bring you the definitive list of top CPUs. [CPUPro]
