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 '16CPUPro]
