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 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]
