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 Ryzen 5 2600, from AMD’s second generation (Zen+) of high-end desktop Ryzen processors, supersedes the first generation Ryzen 5 1600. The newer generation sees a lithography reduction from 14nm to 12nm, but no increase in the number of cores and threads (6 and 12 respectively) over the ground-breaking first generation which continues to surpass similarly priced Intel CPUs in terms of multi-core performance. In other words, progress between generations is predominantly driven by power efficiency and therefore higher attainable clock speeds. The 2600 appears to have a stock base/boost clock of 3.4 / 3.9 GHz compared to the 1600’s 3.2 / 3.6 GHz which is expected to result in a modest increase in effective speed that said, early benchmarks are inconclusive. Included in the expected retail price of about $200 is a Wraith Stealth cooler, so the 2600, like the 1600 before it, represents great value for money, especially for workstation users. The 2600 compliments the new 400 series motherboards and is also backwards compatible with the 300 series following a bios update. [Apr '18 CPUPro]
