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]

Intel’s Core i7-9700K is an unlocked 9th generation Coffee Lake CPU. It is an 8 core, 8 thread processor. The 9700K features 12 MB of cache, a 95W TDP and Intel UHD 630 graphics. Like the other 9th generation chips, it is compatible with Intel’s new Z390 chipset as well as last years Z370 chipset (with an updated BIOS). The 9700K has stock base / boost clocks of 3.6 / 4.6 GHz and a single core boost of 4.9 GHz (compared to 3.6, 4.7 and 5.0 GHz for the flagship 9900K). This translates to almost identical single, quad and octa core performance between the 9900K and 9700K. Mainstream PC games do not benefit from more than eight threads, so at $350 (25% cheaper than the 9900K), the 9700K offers far better value for money to gamers. That said for purely gaming there is very little reason not to consider the i5-9600K which, when overclocked, offers almost equivalent gaming performance but at a 35% discount[Oct '18 CPUPro]
