The Intel i7-4771 is the same as the i7-4770 apart from a 100 MHz increase in base clock from 3.4 GHz to 3.5 GHz. In theory this increase will only impact multi-core workloads because both processors have the same turbo clock of 3.9 GHz which should be engaged during single and dual core workloads. On multi-core workloads the turbo needs to be disabled in order to maintain acceptable core temperatures and operating frequencies drop to base clock where the i7-4771 has a marginal 100 MHz or 2.9% advantage. In other words the two processors should be largely identical. Looking at the i7-4770 vs the i7-4771 benchmarks verifies this. Both the 4770 and 4771 are the current top end mainstream market leaders but for the vast majority of desktop users they are probably overkill as typical consumer use rarely requires more than two cores. [Mar '14 CPUPro]

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]
