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]

The Ryzen 5 1400 is the entry-level chip from AMD's latest Ryzen 5 series which is aimed at the mainstream market. The 1400 is a budget quad core, 8 threaded CPU with base/boost clocks of 3.2/3.4 GHz. Like most the other non-X Ryzen CPUs the 1400 comes with a decent cooler included in the box (Wraith Stealth in this case). Modestly priced at $169 the 1400 is in direct competition with Intel's recent Kaby Lake dual core, four threaded i3-7350k which runs at a base clock of 4.2GHz. The 1400's 8 threads allow a near 40% lead in multi-core processing, but for single-core tasks the 7350K is 45% faster. The Ryzen 5 1500X commands a $20 premium and offers a 25% increase in effective speed over the 1400. Although the 1400 only has a base clock of 3.2 GHz it should more or less match the 1500X when overclocked. Provided it is overclocked, the 1400 joins the other non-X Ryzen models in offering the best bang for your buck. Users not keen on overclocking would probably do better to consider the 1500X at this price point. [Apr '17 CPUPro]
