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]

Early Q3 of 2019 sees the release of the new Ryzen 5 3600X: a hex-core, 12-thread processor. AMD are releasing five new CPUs based on their latest Zen 2 microarchitecture which delivers approximately 13% better IPC than the previous 12nm Zen+. For workstation builds the 3600X is viable, however, the $200 USD Ryzen 5 3600 represents a far better value proposition. The additional $40 USD for the 3600X basically buys a better cooler (Spire vs Stealth). This allows for an extra 200 MHz of extra base and boost clock: 3.8 / 4.4 GHz on the 3600X vs 3.6 / 4.2 GHz on the 3600, this translates to approximately 2% higher overclocked performance for 20% more money. Neither of the stock coolers on the 3600 or 3600X are as effective as a $20 USD aftermarket cooler such as the Gammaxx 400. The 3600 with a Gammaxx 400 outperforms the 3600X with a Spire cooler and when both use a Gammaxx 400 they are more or less identical. The 3600X SKU is basically a marketing gimmick designed to milk unsuspecting consumers. Comparing the 3600X to Intel’s overclocked flagship i5-9600K shows that although the 3600X has 29% faster 64-core speed, it is around 11% worse for gaming (sub eight core performance). Additionally, the 3600X's memory controller, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency which can also impact gaming. The arrival of Zen 2 marks the end of the "Sandy Bridge (i5-2500K)" era, Intel can no longer rely exclusively on their single-core advantage to dominate the market, they must also compete on price. [Jul '19 CPUPro]
