The Intel Core i5-6600K is based on the new "Skylake" 14nm manufacturing process. Sporting 4 physical cores with base/turbo clocks of 3.5/3.9 GHz the 6600K and its predecessor, the 4690K share the same basic configuration and disappointingly, offer similar performance. Comparing the 6600K and 6700K shows that the 6700K has faster multi and single core performance. The improved multi core performance is due to Hyperthreading which is the key differentiator for the i7-6700K. The gap in single core performance can largely be eliminated by overclocking the i5-6600K so although the stock effective speed is significantly higher on the 6700K, this gap diminishes significantly when both processors are overclocked. At a 30% discount, the 6600K is the better value gaming CPU. [Aug '15 CPUPro]

MORE DETAILS

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]
