The Core i7-6700K is Intel's latest "Skylake" flagship processor. It replaces the hugely successful i7-4790K and takes the crown as the fastest mainstream consumer CPU available. Comparing performance and specs between the 4790K and 6700K shows that the configuration is largely unchanged (same base clocks, cores, threads) but the improved manufacturing process (14nm) brings a small reduction in TDP and a performance improvement of 8%; almost exactly the same jump as between the Ivy Bridge 3770K and Haswell 4770K. Owners of any unlocked-K Intel CPU from Sandy Bridge or onwards still have no real reason to upgrade as the performance improvements are largely academic but the i7-6700K will be the CPU of choice for the vast majority of top end PC builds in 2015. [Aug '15 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]
