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]

The i7-8700K is Intel’s latest, top of the range, 8th generation Coffee Lake processor. Like Kaby Lake and Sky Lake before that, Coffee Lake is based on Intel’s 14nm architecture which has been slightly optimized on each iteration. Following AMD’s modus operandi, Intel has upped the cores and threads across the range of their CPUs. In previous generations, a 6-core processor would have been a high-end desk-top (HEDT) processor, however the i7-8700K is the first Intel CPU with 6 cores and 12 threads to be classified (and priced) as a mainstream consumer processor. Specifically, the i7-8700K features a base clock speed of 3.7 GHz which boosts to 4.7 GHz (4.5 GHz for the previous generation i7-7700k), 12MB of smart (L3) cache and 2 channels of DDR4 RAM. The majority of the performance improvements over the 7th generation stem from the higher core count which results in a 50% increase in multi-core speed between the i7-7700k and i7-8700k. A new motherboard will need to be factored into the budget when upgrading to the 8700K as it requires a new Intel Z370 chipset which has supposedly been designed to better deliver power to CPUs with a greater number of cores. Also available in this latest release of CPUs is the 6 core 6 thread i5-8600k which is a more rational option (around $100 cheaper) for the vast majority of users that don’t require hyper-threading. Sandy bridge owners can finally justify an upgrade but with the next iteration of AMD's Zen architecture just around the corner the CPU market will be a lot faster moving now that Intel, once again, has to compete. [Sep '17 CPUPro]
