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]

MORE DETAILS

The Core i5-4690 is Intel's latest and greatest locked Core-i5. This CPU will suit serious gamers that don't plan on overclocking. The 4690 replaces the 4670 and shares exactly the same specs aside from base and turbo clock bumps of 100 MHz. The 100 MHz clock bump results in barely noticeable real world performance improvements and, if anything, makes the older 4670 more attractive as suppliers reduce prices to try to clear stocks. For regular desktop use such as email, surfing, and listening to music, this CPU is overkill and there is far better value amongst lower powered and significantly cheaper CPUs but for gamers and moderate power users the 4690 is a good locked option. [Jun '14 CPUPro]
