CPU Comparison
Intel Core i5-11600KF vs Core i7-11700K
A side-by-side comparison of specs, performance and value. The Intel Core i5-11600KF is a 6-core, 12-thread desktop processor released in March 2021. Based on the Rocket Lake architecture, it brings Cypress Cove cores to the LGA 1200 socket, offering notable IPC improvements over 10th Gen. The 'KF' suffix denotes an unlocked multiplier and the absence of integrated graphics, requiring a dedicated GPU. It features a base clock of 3.9 GHz and a maximum turbo frequency of 4.9 GHz. With a 125W base TDP, it is built on a 14nm process node.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Capable multi-threaded performance for typical productivity applications.
Strong application performance thanks to high clocks and IPC improvements.
Gaming
Handles modern games easily at 1080p and 1440p when paired with a mid-to-high-end GPU.
Excellent 1080p and 1440p gaming performance, trading blows with AMD's Ryzen 7 5800X.
Virtualization
Adequate for light virtualization tasks, though limited to 6 cores.
16 threads handle virtualization well, but lacks quad-channel memory of HEDT.
Efficiency
Power consumption is high under load due to the 14nm process pushing high clocks.
Power draw can exceed 250W under all-core load; efficiency lags behind TSMC 7nm nodes.
