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 i7-9700K is an unlocked 9th generation Coffee Lake CPU. It is an 8 core, 8 thread processor. The 9700K features 12 MB of cache, a 95W TDP and Intel UHD 630 graphics. Like the other 9th generation chips, it is compatible with Intel’s new Z390 chipset as well as last years Z370 chipset (with an updated BIOS). The 9700K has stock base / boost clocks of 3.6 / 4.6 GHz and a single core boost of 4.9 GHz (compared to 3.6, 4.7 and 5.0 GHz for the flagship 9900K). This translates to almost identical single, quad and octa core performance between the 9900K and 9700K. Mainstream PC games do not benefit from more than eight threads, so at $350 (25% cheaper than the 9900K), the 9700K offers far better value for money to gamers. That said for purely gaming there is very little reason not to consider the i5-9600K which, when overclocked, offers almost equivalent gaming performance but at a 35% discount[Oct '18 CPUPro]
