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]

The 6 core, 12 thread Ryzen 5 2600X is one of four new AMD second generation of high-end desktop Ryzen processors (codenamed Pinnacle Ridge) renowned for excellent value multi-core performance. The 2600X is set to replace the also 6 core, 12 thread 1600X as AMD’s new mid-range Ryzen 5 flagship. The latest generation of CPUs features a matured Zen+ chip architecture with 12nm lithography, increased clock speeds and Precision Boost 2 technology designed to leverage more CPU power than per the first generation. The 2600X appears to have stock base / boost clock speeds of 3.6 / 4.2 GHz. This is only marginally faster than the 1600X’s 3.6 / 4.0 GHz. Modest effective speed improvements are expected, although further benchmarks are necessary to draw firm conclusions. The 2600X ships with a Wraith Spire cooler and is priced reasonably at an expected $250. However, for most use cases, the new lower clocked Ryzen 5 2600 at $200 represents better value for money. Pinnacle Ridge processors are designed to work with the new 400 series motherboards, which allow for greater overclocking head room, and they are also backwards compatible with the 300 series motherboard following a bios update. [Apr '18 CPUPro]
