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 Intel Core i5-750 is a mid-range quad core, four thread desktop processor which is part of the Nehalem series launched in Q3 2009. Considering the age of this processor, its effective speed of 67 is damn impressive. It has a base frequency of 2.66 GHz, which boosts to 3.2 GHz turbo when under load and can be significantly extended beyond by overclocking. Combined with a decent graphics card, the i5-750 should give a reasonable gaming experience even by today’s standards. There are of course faster modern alternatives such as the i5-4690K, but if you already have the 750 with an older graphics card it's likely that your GPU will need updating before the CPU. Comparing the 750 and 4690K shows that the 4690K has an effective speed of 109 which is 62% faster than the now five years old i5-750. [Nov '14 CPUPro]
