The unlocked hex-core i5-8600K from Intel’s latest Coffee Lake generation of processors is the new flagship of the i5 series, succeeding the Kaby Lake quad-core i5-7600K. The 8th generation of processors brings the largest performance uplift since Sandy Bridge by adding more cores at each of the i3, i5 and i7 product lines. Like the other Coffee Lake processors, the i5-8600K is built upon optimized 14nm architecture, marginally improved upon from Kaby Lake and Skylake. The 8600K has a 95W TDP and a nominal stock clock of 3.6 GHz, which boosts to 4.1 GHz for all six cores, 4.2 GHz for dual/quad and 4.3 GHz for single core. Early benchmarks put the i5-8600K’s effective speed 15% ahead of the i5-7600K. A 50% increase in multi-core speed is explained by two additional cores and thanks to the quad-core clock bump from 4 GHz on the 7600K to 4.2 GHz on the 8600K there is also an additional 5% performance boost across all workloads. All Coffee Lake processors require a 300-series chipset, making a straight CPU upgrade unfeasible despite sharing the same socket as their Z270 predecessors. Even though most games still use less than 4 cores simultaneously, the i5-8600K is a great choice for gamers but for $80 less, the 8350K which is faster than last years 7600K and only marginally weaker for gaming than the 8600K is certainly well worth considering as well. [Oct '17 CPUPro]

Intel’s tenth generation octa-core hyperthreaded i7-10700K is one of the fastest high-end desktop CPUs ever made. A simple overclock yields all 16 threads running at a staggering 5.1 GHz. Gaming and desktop performance is second only to the flagship i9-10900K. Although a new (Z490) LGA1200 motherboard is required, it will remain compatible with Rocket Lake CPUs which are due later this year. The 10700K’s $400 USD price tag puts it in a similar price band to AMD’s 12-core hyperthreaded Ryzen 9 3900X, however, the 10700K’s faster cores combined with its lower memory latency, yield a 12% effective speed advantage over the 3900X. Intra-generationally comparing the 10700K and 10600K shows that the 10600K offers almost identical gaming performance for 34% less money. [Jun '20 CPUPro]
