CPU Comparison
Core i7-11700K vs Intel Core i7-11700KF
A side-by-side comparison of specs, performance and value. The Intel Core i7-11700K is a desktop processor released in March 2021 as part of the 11th Generation Rocket Lake-S lineup. Designed for the LGA 1200 socket, it features 8 cores and 16 threads, leveraging Intel's Cypress Cove architecture to deliver a significant instructions-per-clock (IPC) uplift over the previous generation. Operating at a base frequency of 3.6 GHz and boosting up to 5.0 GHz, the processor targets high-performance gaming and content creation. It brings PCIe 4.0 support to the Intel mainstream desktop platform for the first time, offering 20 direct lanes for faster graphics and storage communication. Despite being built on the mature 14nm process node, it manages to integrate the UHD Graphics 750, providing decent entry-level graphical capabilities. However, the architectural backport results in higher power consumption under heavy multi-core workloads compared to AMD's competing 7nm Ryzen processors. Nevertheless, it remains a compelling choice for users seeking strong single-threaded performance on existing Intel motherboards.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Strong application performance thanks to high clocks and IPC improvements.
8 cores at 5.0 GHz make short work of compilation and rendering tasks.
Gaming
Excellent 1080p and 1440p gaming performance, trading blows with AMD's Ryzen 7 5800X.
Outstanding gaming performance, easily pushing 240Hz+ in esports titles when paired with fast RAM and a high-end GPU.
Virtualization
16 threads handle virtualization well, but lacks quad-channel memory of HEDT.
Strong core count and clock speeds provide excellent VM performance.
Efficiency
Power draw can exceed 250W under all-core load; efficiency lags behind TSMC 7nm nodes.
The 14nm process at 125W+ is highly inefficient and generates massive heat under load.
