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]

The Ryzen 5 2600, from AMD’s second generation (Zen+) of high-end desktop Ryzen processors, supersedes the first generation Ryzen 5 1600. The newer generation sees a lithography reduction from 14nm to 12nm, but no increase in the number of cores and threads (6 and 12 respectively) over the ground-breaking first generation which continues to surpass similarly priced Intel CPUs in terms of multi-core performance. In other words, progress between generations is predominantly driven by power efficiency and therefore higher attainable clock speeds. The 2600 appears to have a stock base/boost clock of 3.4 / 3.9 GHz compared to the 1600’s 3.2 / 3.6 GHz which is expected to result in a modest increase in effective speed that said, early benchmarks are inconclusive. Included in the expected retail price of about $200 is a Wraith Stealth cooler, so the 2600, like the 1600 before it, represents great value for workstation users. The 2600 compliments the new 400 series motherboards and is also backwards compatible with the 300 series following a bios update. Even though the 2600 is plausible for multimedia production streamers should look elsewhere. Streaming with dedicated hardware such as NVENC or a separate stream PC will nearly always result in fewer dropped frames. [Apr '18 CPUPro]
