The Intel i5-4200U is a dual core 4th generation Haswell processor. Specifically designed for tablets and ultrabooks it gives the appropriate balance between performance and battery life. The i5-4200U has integrated HD 4400 graphics which are fine for desktop use but not suited to 3D gaming. With an impressive TDP of just 15 Watts, the 4200U will typically give 6 hours of battery life. Despite the low effective speed of 56 which is 70% below the average of the leaders, when coupled with an SSD the 4200U can give a reasonable user experience. Comparing the 4200U and 4500U shows that the 4500U has 20% faster single-core performance but also costs 40% more. [Nov '14 CPUPro]

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]
