The Intel Core i5-6600K is based on the new "Skylake" 14nm manufacturing process. Sporting 4 physical cores with base/turbo clocks of 3.5/3.9 GHz the 6600K and its predecessor, the 4690K share the same basic configuration and disappointingly, offer similar performance. Comparing the 6600K and 6700K shows that the 6700K has faster multi and single core performance. The improved multi core performance is due to Hyperthreading which is the key differentiator for the i7-6700K. The gap in single core performance can largely be eliminated by overclocking the i5-6600K so although the stock effective speed is significantly higher on the 6700K, this gap diminishes significantly when both processors are overclocked. At a 30% discount, the 6600K is the better value gaming CPU. [Aug '15 CPUPro]

AMD released the FX-9590 back in July 2013 but it's not until recently that these processors have started hitting the shelves and even now prices are still extremely high. This is the first mainstream 5GHz processor but clock speed isn't the key performance indicator it once was. Comparing the 9590 to the 8350 shows that the 9590 has 16% better overall performance which is almost exactly in line with its base clock increase from 4.0 to 4.7 GHz. Despite this performance boost the 9590 still lags Intel's most recent 4770K Haswell processor by 26% and that's despite the AMD's 27% higher base clock. In terms of relative performance the AMD's strong point is Integer processing where it has 8 processing units vs just four (one per core) in the 4770K. Overall, especially at current prices, the 9590 doesn't represent good value for money. [Jan '14 CPUPro]

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]
