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]

The Core i7-6800K is the weakest of four new 14 nm Broadwell-E prosumer CPUs. This model has six cores with base and turbo frequencies of 3.4 and 3.8 GHz, a TDP of 140 watts and 28 PCIe 3.0 lanes. The 6800K closely matches, and supersedes, the very popular Haswell-E 5820K. Because of its MSRP of around $500, this CPU only makes sense for niche use cases which include graphics design, video production or multi GPU gaming. Comparing the 6800K and 6700K shows that for typical desktop use, at stock clocks, the 6800K actually lags the 6700K by around 10%. This is because desktop computing largely depends on single core performance and the Skylake i7-6700K is both clocked higher (Base clock 4.0 GHz vs 3.4 GHz) and has higher IPC due to its one generation lead over the 6800K. If the 6800K proves to be a capable overclocker then it may challenge the 6700K on a range of core-heavy use cases, time will tell. [Jun '16 CPUPro]
