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 i3-4370 is a mid-range dual-core four threaded 4th generation (Haswell) processor. It was released in Q3 2014 and thanks to its base frequency of 3.8 GHz, it scores a very respectable 96 for effective speed. Whilst this is fast enough to run nearly all applications smoothly, 3D graphics performance is limited by the integrated Intel HD Graphics 4600. Although the 4370 is currently the fastest i3, it’s worth considering the i3-4160 which offers significantly better value for money. Comparing the 4160 and 4370 shows that the 4160 is 22% cheaper but only 5% slower in terms of effective speed. [Nov '14 CPUPro]
