The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '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]
