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

LGA185120 cores / 20 threads

Released October 10, 2024 ·

Intel's second-tier Arrow Lake part: 20 cores split 8 Performance and 12 Efficient reach a 5.5GHz boost from a 3.9GHz P-core base, with 30MB of L3 cache. It shares the exact core layout of the outgoing 14700K, but drops Hyper-Threading, so its 20 threads sit where the 14700K's 28 did, and its 5.5GHz peak boost lands 100MHz under that chip's 5.6GHz. Maximum turbo power still tops out at 250W, the same ceiling as the flagship 285K above it. At $404 boxed, it suits buyers who want the new platform without paying for the top SKU.

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 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Much lower power draw than the previous generation with solid multi-threaded performance and really low temperatures.
  • Owners describe strong all-round performance for gaming and productivity, with smooth multitasking.
  • It is repeatedly reported to run cool and quiet with an AIO, even without BIOS tuning.
  • Owners upgrading from much older platforms report a large, easy performance jump.
  • Several call it good value, particularly with bundles or a bundled cooler.

Commonly criticised

  • Surprisingly poor gaming performance, a required new motherboard, and too expensive for the performance on offer.
