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]

The Intel Core i5-4590 is a slightly upgraded version of the i5-4570. The two processors are identical apart from a 100 MHz increase in base and turbo frequencies. Needless to say the two processors have almost identical effective speeds which is a little disappointing as Intel has simply re-released a near identical product. From a value for money perspective the 4590 does fare reasonably well although it probably has more multi-core horsepower than most use cases demand. For the majority of users, at stock clocks, the G3258 provides comparable performance but with a few simple BIOS adjustments the G3258 can be clocked up to 4.3 GHz where, even at half the price, it destroys the i5-4570 in single and dual core workloads. [Sep '14 CPUPro]

Processor Rankings (Price vs Performance) April 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]
