The Core i7-6900K is one of four new Broadwell-E prosumer CPUs. This model has eight cores with base and turbo frequencies of 3.2 and 4.0 GHz respectively. The 6900K is based on a 14 nm architecture, it has a TDP of 140 watts, 40 PCIe 3.0 lanes and no integrated graphics. Because of its MSRP of $1,100, the 6900K only makes sense for very niche use cases which include top end graphics design and video production. Comparing the 6900K and 6700K shows that for typical desktop use the 6900K only offers a gain of around 12% for a whopping three fold price increase. This is because desktop computing largely depends on single core performance and the Skylake i7-6700K is both clocked higher and has higher IPC due to its one generation lead over the 6900K. That said, as a workstation CPU the 6900K is bested only by the $2,000 flagship ten core 6950X. (6900K vs 6950X[Jun '16 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 barely pulls ahead in any of the top five games[Oct '19 CPUPro]
