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 Ryzen 5 1600 is one of four new Ryzen 5 processors released this month. Based on the AMD Zen architecture, which is comparable to Intel in terms of IPC, the Ryzen 5 1600 has six cores which is more than the vast majority of games are able to use (most games cannot use more than four cores). Ryzen 5 CPUs offer gamers better value for money than the eight core Ryzen 7 models released last month. With six cores the 1600 is approximately 75% better at multi-threaded tasks than Intel's quad core i5 flagship – the similarly priced i5-7600K, the 1600 however, has 25% lower single and 33% lower quad core scores. The 1600 has stock base/boost clock speeds of 3.2/3.6 GHz and its price tag of $219 includes a cooler. Assuming a modest overclock of 10% brings the 1600 within striking range of the 1600X which is the Ryzen 5 flagship. The 1600X sports stock base/boost clocks of 3.6/4.0 GHz but costs $30 more than the 1600 and ships without a cooler included in the box. The Ryzen 5 1600 is the best value for money six core CPU we have seen to date. [Apr '17 CPUPro]

Processor Rankings (Price vs Performance) January 2018 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]
