A side-by-side comparison of specs, performance and value. The Intel Core i5-11600K is a 6-core, 12-thread desktop processor launched in March 2021. Based on the Rocket Lake architecture, it utilizes the Cypress Cove microarchitecture on Intel's 14nm process. Featuring a base clock of 3.9 GHz and a turbo boost of 4.9 GHz, it targets mainstream gamers and enthusiasts. Unlike the KF variant, it includes Intel UHD Graphics 750. With a 125W base TDP, it offers unlocked overclocking and 20 PCIe 4.0 lanes, bringing next-gen connectivity to the LGA 1200 platform.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Capable multi-threaded performance for typical productivity applications.
8 cores at 5.0 GHz make short work of compilation and rendering tasks.
Gaming
Handles modern games easily at 1080p and 1440p when paired with a mid-to-high-end GPU.
