The Core i7-6850K is one of four new Broadwell-E prosumer CPUs. This model has six cores with base and turbo frequencies of 3.6 and 4.0 GHz respectively. The 6850K is based on the 14 nm Broadwell-E architecture. It has a TDP of 140 watts, 40 PCIe 3.0 lanes and no integrated graphics. Because of its relatively high MSRP of around $700, this CPU only makes sense for niche use cases which could include top end graphics design or video production workstations. Comparing the 6850K and 6700K shows that for typical desktop use the 6850K only offers a gain of around 10% for a whopping two 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 6850K. [Jun '16 CPUPro]

MORE DETAILS

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]
