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 1600X is the flagship processor from AMD's latest generation of Ryzen 5 processors which feature the Zen architecture. Following on from last month's release of the Ryzen 7 series, the Ryzen 5 series is positioned as a less expensive mid-performance alternative to Intel's i5 mainstream offerings. Once again, AMD excels in multi-core technology. Like the Ryzen 5 1600, the 1600X features 6 cores and 12 threads, but has roughly 11% higher clock speeds (out of the box) for a 14% premium. Like all Ryzen CPUs the 1600X is unlocked. The 1600X is the only Ryzen 5 CPU with a TDP of 95W, the 1600, 1500X and 1400 all have 50% lower power consumption of 65W. Due to its high thread count, UserBenchmarks show that at stock clocks the 1600X outperforms the i7-7700k on multi-threaded tasks by 23%, but it lags behind by 23% for single and 14% for quad-core performance. The 1600X is priced keenly at $249 so a more appropriate CPU comparison is the i5-7600k where the 1600X wins on stock multi-core by a whopping 81%. The 1600X does represent great value for workstation users that also game but its $30 cheaper sibling, the 1600 (non x version), which includes a cooler and has great overclocking potential out of the box is arguably the the value king in this segment. [Apr '17 CPUPro]
