The i5-7600K targets high end gamers, it sits just behind the flagship i7-7700K in Intel’s Kaby Lake lineup. The 7600K will likely be the most popular gaming CPU of 2017 (some competition from AMD’s upcoming Zen/Ryzen CPUs, would be very welcome). Comparing the 7600K and 6600K shows that the two processors are very closely matched and comparing the 7600K vs the hyper-threaded 7700K highlights the relative strength of the 7700K for workstation performance. There are no significant architectural differences between Kaby Lake and Skylake so, when fully overclocked, the two generations should perform similarly but Kaby Lake offers faster base clocks, improved speed shift technology which helps CPU responsiveness, and better integrated graphics[Jan '17 CPUPro]

The i3-9350KF is a 9th generation quad core Coffee Lake CPU which is designed to be used with a discrete graphics card. It has base/boost turbo frequencies of 4.0/4.6 GHz. The 9350KF generates less heat than its higher core "K" counterparts so getting a decent overclock without expensive cooling is relatively straightforward. Overclocking the 9350KF to 5 GHz with a $20 USD Gammaxx 400 cooler puts the 9350KF at similar single, dual and quad core performance levels as the 9600K, 9700K and 9900K SKUs. Consequently there is not much difference in fps between the 9350KF and any other CPU regardless of core count. At $180 USD the 9350KF sits amongst the top value gaming and desktop CPUs currently available. Comparing the 4 thread 9350KF to AMD’s twice as expensive 16 thread Ryzen 3700X shows that the 9350KF wins hands down in all five of today’s most popular games. The only other CPUs worth considering for unbeatable gaming performance are the 9600K or 9600KF which have 50% more, equally fast cores, for less than 10% more money.  [Nov '19 CPUPro]
