The hex-core i5-9600K is third in Intel’s line-up of 9th generation Coffee Lake CPUs. It has a TDP of 95W and requires an aftermarket cooler ($30+). The 9600K was designed to be overclocked. Once this is enabled in the BIOS (requires a Z-series motherbaord), the 9600K runs 10% faster. In terms of performance, the i5-9600K is almost unbeatable for desktop users and it has sufficient multi-core performance to handle all but the most demanding workstation tasks. For Heavy workstation users the Ryzen 3000 series offers great 64-core performance at a very competitive price. For example the overclocked Ryzen 3600 is approximately 13% worse for gaming and desktop (sub octa-core tasks) but it is 27% faster for 64-core processing. At stock clocks the i5-9600K is around 8% slower than Intel’s flagship i9-9900K but when both are overclocked, the 9600K closes the gaming gap to within two or three percent. Considering that the 9900K is the fastest gaming processor available, and almost twice the price of the 9600K, this is no small feat. The i5-9600K is aimed squarely at gamers who are not willing to compromise on performance but don't want to pay more than they need to. [Oct '18 CPUPro]
