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]

AMD’s Ryzen 5 3600 is one of five new processors based on the latest Zen 2 7nm microarchitecture. This 6-core, 12-threaded processor is priced at $199 USD and succeeds the Zen+ Ryzen 5 2600 improving upon it by 18% in terms of average effective speed and 12% in terms of overclocked performance. The 3600's base / boost clocks of 3.6 / 4.2 GHz match the previous gen hex-core Ryzen 5 2600X and therefore indicate an 11% clock for clock (IPC) improvement over the previous generation. The Ryzen 5 3600 is in competition with Intel’s hex-core i5-9600K. AMD continues to push the multi-core performance envelope: benchmarks show that the 3600 has a 27% overclocked 64-core advantage over the 9600K but that the i5-9600K leads by 14% on single, quad and hex core workloads which translates to 14% higher fps for gamers. Additionally, the 3600's memory controller, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency which can impact gaming. The Ryzen 3000 processors all include coolers and although they will be launched alongside the new mainstream X570 chipset (which is PCIe 4.0 enabled), they are backwards compatible with 400 and even the 300 series motherboards. At $198 USD, the 3600 offers reasonable value for workstation users. [Jun '19 CPUPro]
