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 (such as the $20 GAMMAXX 400). The 9600K was designed to be overclocked. Once this is enabled in the BIOS (requires a Z-series motherboard), 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 CPU encoding (Cinebench, Blender, Handbrake etc.) the Ryzen 3000 series offers great 64-core performance. For example the overclocked Ryzen 3600 is approximately 13% worse for gaming, desktop and normal consumer workloads but it is 27% faster for 64-core processing. CPU encoding is akin to using hair clippers on a lawn, encoding tasks are far better performed by dedicated hardware such an NVENC or QuickSync. 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]

The Intel Core i7-3770 is an Ivy Bridge processor. With four cores and eight threads the 3770 has excellent single , dual and multi-core performance. Comparing the 3770 to the 4770K shows that the 4770K leads by 11% at stock speeds and, thanks to an unlocked multiplier on the 4770K, by 15% at overclocked frequencies. The i7-3770 has a very strong performance profile which includes multi-core capabilities that are likely to be overkill for the majority of desktop users. Comparing the 3770 to the 3770K shows that the unlocked 3770K allows for, on average, an additional 8% increase in performance. [Mar '14 CPUPro]
