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 7 2700 is an 8 core, 16 thread high-end desktop processor featuring AMD’s second generation 12nm Zen+ architecture and Precision Boost 2 technology. It is the second strongest of four new Ryzen CPUs due for imminent release. The second generation Ryzen processors, codenamed Pinnacle Ridge, are both compatible with the new 400 series and 300 series of motherboards. Official specs for the 2700 are yet to be seen, but early benchmarks appear to indicate base and boost clock speeds of 3.2 and 4.1 GHz respectively. This translates to a modest improvement upon the previous generation 1700 which continues to offer fantastic value for money in terms of multi-core performance. The expected retail price of $299 includes a Wraith cooler and costs the same as Intel’s 6 core 12 thread i7-8700. As expected, the 8700 beats the 2700 on single and quad core intensive tasks, but lags behind for higher core workloads.  [Apr '18 CPUPro]
