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 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]
