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 Core i3-9100F is a quad-core 9th generation Coffee Lake desktop processor. It features base / boost clocks of 3.6 / 4.2 GHz, 6 MB of cache, a 65W TDP and it ships with a cooler. Gamers should pair the 9100F with a Z390 motherboard and unlock higher XMP RAM speeds. This will deliver up to a 15% fps boost which is well worth it considering that many Z390 boards are available for around $100 USD (here is one of the builds from our EFps test lab). The 9100F has great single core performance coupled with a strong memory sub system. This enables it to deliver excellent all round performance, easily holding its own against far pricier CPUs for the majority of use cases. The heavily hyped 12 threaded 6 core Ryzen 3600, paired with a 2060S, barely pulls ahead in any of the top five games. [Oct '19 CPUPro]
