Intel Core i5-9600K
The Core i5-9600K may not have the core-count increases of its higher-priced siblings, but it received a healthy frequency bump over its predecessor, coupled with hardware patches to some vulnerabilities. We already proved that the i7-9700K is the best gaming CPU by Intel.
Practically same gaming performance as i7-9700K and i9-9900K at any resolution; High performance in less-parallelized or single-threaded workloads; Reasonably high multi-threaded performance; Unlocked multiplier; Integrated graphics; Supports up to 128 GB memory
Expensive; made worse by high DIY retail channel pricing; Lacks HyperThreading; No cooler included; unlike competition
