Core Ultra 5 250K Plus Spec and Price in the United Kingdom

LGA185118 cores / 18 threads

Released March 26, 2026 ·

The mid-tier Arrow Lake Refresh part: 18 cores split 6 Performance and 12 Efficient, a 5.3GHz boost from a 4.2GHz P-core base, and 30MB each of L3 and L2 cache. Its 159W maximum turbo power sits far below the 270K Plus's 250W, so it asks less of a cooler while sharing the same LGA1851 socket and DDR5-7200 memory support. Hyper-Threading is absent here as across Arrow Lake, so 18 cores carry 18 threads. It lists at $229 boxed.

Tied 31st of 65 models in the CPU catalog on Boost clock — 8 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

  • A welcomingly low price with unbeaten productivity value and great multi-core pace.
  • Solid power efficiency with an optimization feature, a high-value chip for creators.
  • Owners call it outstanding value, delivering strong gaming and multitasking performance at a low price.
  • It is repeatedly described as running cool and quiet, making it a good fit for small or quiet builds.
  • Owners coming from AMD systems report smooth gaming and better frame-time lows when running heavy background work.

Commonly criticised

  • Some gaming shortfalls, and it limits the fastest storage speeds.
  • It needs an up-to-date BIOS to run at proper speed and to report the correct model name.
  • Owners complain the price rose between restocks during the launch period.
