The Core i7-6700K is Intel's latest "Skylake" flagship processor. It replaces the hugely successful i7-4790K and takes the crown as the fastest mainstream consumer CPU available. Comparing performance and specs between the 4790K and 6700K shows that the configuration is largely unchanged (same base clocks, cores, threads) but the improved manufacturing process (14nm) brings a small reduction in TDP and a performance improvement of 8%; almost exactly the same jump as between the Ivy Bridge 3770K and Haswell 4770K. Owners of any unlocked-K Intel CPU from Sandy Bridge or onwards still have no real reason to upgrade as the performance improvements are largely academic but the i7-6700K will be the CPU of choice for the vast majority of top end PC builds in 2015. [Aug '15 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) 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]
