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]

Intel’s Core i7-9700K is an unlocked 9th generation Coffee Lake CPU. It is an 8 core, 8 thread processor. The 9700K features 12 MB of cache, a 95W TDP and Intel UHD 630 graphics. Like the other 9th generation chips, it is compatible with Intel’s new Z390 chipset as well as last years Z370 chipset (with an updated BIOS). The 9700K has stock base / boost clocks of 3.6 / 4.6 GHz and a single core boost of 4.9 GHz (compared to 3.6, 4.7 and 5.0 GHz for the flagship 9900K). This translates to almost identical single, quad and octa core performance between the 9900K and 9700K. Mainstream PC games do not benefit from more than eight threads, so at $350 (25% cheaper than the 9900K), the 9700K offers far better value for money to gamers. That said for purely gaming there is very little reason not to consider the i5-9600K which, when overclocked, offers almost equivalent gaming performance but at a 35% discount[Oct '18 CPUPro]
