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.
