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]

The Ryzen 7 1800X is AMD's flagship Ryzen CPU. Clocked at 3.6 GHz with a turbo frequency of 4.0 GHz (stock) this chip offers a staggering level of multi-core performance. Comparing the 1800X with the Intel i7-6850K shows that the 1800X delivers 25% more multi-core throughput than its more expensive counterpart. Historically AMD's CPU architecture has had a much lower IPC than Intel's and consequently Intel have dominated the CPU market since 2009. Comparing IPC between Intel's Kaby Lake and Ryzen shows a maximum gap of just 9%. A very welcome shake-up of the CPU market will unfold as the remaining Ryzen 5 and Ryzen 3 models are rolled out. For now the 1800X offers workstation users similar processing power to a $1,000 i7-6900K at half the price. [Mar '17 CPUPro]
