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 AMD Ryzen 7 1700X isn't due for release until next week but two of our users has already submitted benchmarks. Comparing the quad and single core scores from our samples shows a relative 4.3% boost on the single core score so it’s possible that turbo wasn’t fully engaged (12% turbo boost expected). These preliminary results are seriously impressive as they put Zen’s IPC between 0% and 9% below Intel’s Kaby Lake. Even in the worst case scenario these results are still impressive. Comparing Intel’s $1,000 6900K and the 1700X shows that AMD delivers comparable performance for half the price! A shake-up of the CPU market will unfold as Zen rolls out. If Ryzen CPUs can overclock to 4.6+ GHz they will likely dominate the entire market putting a very welcome end to the monotonous tick-tock of recent years. [Feb '17 CPUPro]
