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 '15CPUPro]
These APUs are still good candidates for budget eSport gaming and most AAA titles with the sole exception of CP2077.
However, they come with a catch, as you will need to use very high clock speed RAM (DDR3 2133 or 2400 on XMP) to get decent results with the onboard graphics (Which can trade blows with a GT 730 easily), if you want decent single core performance, you will need to overclock them over 4.0GHz base, preferably at 4.5GHz, however, getting past 4.5GHz base will yield you only two overclocked cores and two at idle clockspeed (1.7GHz).
If high speed DDR3 is cheap on your location, get one of these APUs, they are certainly worth it if they are cheap. [Feb '21derwolf019]
We calculate effective speed which measures real world performance for typical users. Effective speed is adjusted by current prices to yield a value for money rating. Our calculated values are checked against thousands of individual user ratings. The customizable table below combines these factors to bring you the definitive list of top CPUs. [CPUPro]
