The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

In terms of raw single-core performance the flagship AMD FX-8350 is lagging behind intel's processor line-up by over two generations. The PassMark Single Thread scores for the i5-2500K vs the FX-8350 are 1863 to 1520 which shows that in terms of raw per-core processing the FX-8350 is lagging the two year old i5 by 23%. Where the AMD FX makes up is on multi-core performance, with a score of 9156 vs 6745, the AMD leads the Intel 2500K by 36% making it the far more capable multi-threaded server orientated performer. The AMD is also cheaper but significantly more power hungry which counts strongly against it as a server proposition. The FX-8350 could be a good fit for specific server use cases but for general consumer use, which is single and dual core intensive, Intel's two year old i5-2500K delivers better performance. [May '13 CPUPro]
