Core i9-13900KF Spec and Price in the United Kingdom

LGA170024 cores / 32 threads

Released October 20, 2022 ·

The F-suffix twin to the 13900K: identical twenty-four cores, 5.8GHz boost and 36MB of L3 cache, with the UHD Graphics 770 die removed so a discrete GPU becomes mandatory. Dropping integrated graphics trims $25 off the 13900K's $599 boxed price, the same gap the smaller K/KF pairs in this lineup show. It suits builders who already have a graphics card and don't need Intel's onboard fallback display.

Tied 3rd of 65 models in the CPU catalog on Boost clock — 2 models share this figure. Tied 24th of 65 models in the CPU catalog on L3 cache — 6 models share this figure.

Guides for this category

How to choose a desktop CPUA chip's socket decides what it can go into; cores, cache and TDP decide what you actually get once it's installed.How many CPU cores you actually needWhy more cores is not more speed, how gaming and productivity ask for cores differently, and why a core count alone never ranks two chips.When a CPU price is actually goodWhy a chip's list price and discount percentage tell you little, what a processor's price does over its life, and how to read its tracked history.Laptop CPU vs desktop CPUA mobile chip with the same core count is not the same processor — what the power envelope changes, and why these parts carry no price.

What owners and reviewers say

Summarised from 2 source(s), reviewed September 14, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Reviewers benchmark it as one of the fastest gaming processors of its launch window, leading the comparison group across a wide set of titles.
  • It tops the synthetic Cinebench and CPU-Z standings in the test set, and tuning its memory frequency and timings measurably lifts its results.
  • Owners describe top-tier multi-core and single-core performance that handles anything thrown at it.
  • Several say it can run cool and reach high clocks when paired with strong cooling and a tuned power limit.
  • It is described as a big upgrade from much older builds for both gaming and productivity.

Commonly criticised

  • Under full load it reaches its thermal limit and draws close to 300W by itself, with ray-traced titles exposing some scheduling weakness in its efficiency cores.
  • It is power-hungry and runs hot, and owners say a high-end AIO or custom loop is needed.
  • Cost is a recurring complaint, with owners recommending waiting for a discount.
  • Several owners warn that motherboard defaults disable power limits, inflating heat and power draw until they are tuned.
