Core Ultra 7 265KF Spec and Price in the United Kingdom

LGA185120 cores / 20 threads

Released October 10, 2024 ·

The F-suffix version of the 265K: identical 20 cores split 8 Performance and 12 Efficient, the same 5.5GHz boost and 30MB of L3 cache, with the integrated Intel Graphics die disabled so a discrete GPU is required. Losing the iGPU is the only change among the specs recorded here versus the 265K, and it comes with a $15 discount — $389 boxed against the 265K's $404. It suits builders who already own a graphics card and don't need Intel's onboard fallback display.

Tied 17th of 65 models in the CPU catalog on Boost clock — 6 models share this figure. Tied 45th 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 measured strong single-core results that often match or exceed the Core i9-14900K, with competitive 3DMark and creative-application numbers.
  • Its power draw and temperatures are markedly lower than the previous generation, peaking around 210W under load and running cooler under heavy tasks.
  • It is positioned as a well-priced middle ground for mixed gaming and work use, especially for those coming from older platforms.
  • Owners upgrading from much older Intel chips report a large jump in gaming and creative-app performance.
  • It is described as running cool and efficiently, taking well to mild undervolting.
  • Several owners say BIOS and firmware updates have improved performance since launch.

Commonly criticised

  • It gives up the integrated graphics of the K model, so a discrete card is required, and benchmarks using all cores still favour the higher-core i9 and Ryzen parts.
  • Owners say the upgrade is worthwhile only from much older chips, not from recent generations.
  • It requires a new motherboard and DDR5 memory, which owners note adds to the total cost.
