Intel are celebrating the 40th anniversary of their x86 architecture and 8086 processor with the launch of their high-end i7-8086K. Just 50,000 units of this hex core, twelve threaded Coffee Lake processor have been made available globally. Exactly like the i7-8700K, the 8086K features 12MB of smart (L3) cache, 2 channels of DDR4 RAM and has a TDP of 95W. Essentially, the 8086K is Intel’s current Coffee Lake flagship, the i7-8700K, with a single-core turbo frequency factory overclocked by 300 MHz. Thermals permitting, out of the box, the i7-8086K achieves a single core boost speed of 5.0 GHz – which is a new record for Intel. That said, you would be unlucky if you were unable to achieve a 5.0 GHz single core OC with an 8700K. For everything other than single core, the turbo clock speeds on the 8086K exactly match the 8700K which puts the 8086K firmly into gimmick territory. Directly comparing the 8086K and 8700K shows that for a $100 (24%) price premium you get around a 5% performance improvement which drops to around 2% when both chips are overclocked. If the price gap between the 8086K and the 8700K were to fall to less than 20 USD it may be worth considering the 8086K. [Jun '18 CPUPro]

The i5-7600K targets high end gamers, it sits just behind the flagship i7-7700K in Intel’s Kaby Lake lineup. The 7600K will likely be the most popular gaming CPU of 2017 (some competition from AMD’s upcoming Zen/Ryzen CPUs, would be very welcome). Comparing the 7600K and 6600K shows that the two processors are very closely matched and comparing the 7600K vs the hyper-threaded 7700K highlights the relative strength of the 7700K for workstation performance. There are no significant architectural differences between Kaby Lake and Skylake so, when fully overclocked, the two generations should perform similarly but Kaby Lake offers faster base clocks, improved speed shift technology which helps CPU responsiveness, and better integrated graphics[Jan '17 CPUPro]
