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 6 core, 12 thread Ryzen 5 2600X is one of four new AMD second generation of high-end desktop Ryzen processors (codenamed Pinnacle Ridge) renowned for excellent value multi-core performance. The 2600X is set to replace the also 6 core, 12 thread 1600X as AMD’s new mid-range Ryzen 5 flagship. The latest generation of CPUs features a matured Zen+ chip architecture with 12nm lithography, increased clock speeds and Precision Boost 2 technology designed to leverage more CPU power than per the first generation. The 2600X appears to have stock base / boost clock speeds of 3.6 / 4.2 GHz. This is only marginally faster than the 1600X’s 3.6 / 4.0 GHz. Modest effective speed improvements are expected, although further benchmarks are necessary to draw firm conclusions. The 2600X ships with a Wraith Spire cooler and is priced reasonably at an expected $250. However, for most use cases, the new lower clocked Ryzen 5 2600 at $200 represents better value for money. Pinnacle Ridge processors are designed to work with the new 400 series motherboards, which allow for greater overclocking head room, and they are also backwards compatible with the 300 series motherboard following a bios update. [Apr '18 CPUPro]
