Intel Core Ultra 5 250KF Plus Unlocked Desktop Processor

Core Ultra Series 2 Plus Arrow Lake Refresh · FCLGA1851 · Boxed (no cooler)
18-Core 18-ThreadUp to 5.3 GHz30 MB Intel Smart Cache CacheUnlocked

The Intel Core Ultra 5 250KF Plus is a Core Ultra Series 2 Plus (Arrow Lake Refresh) desktop processor with 6 Performance-cores + 12 Efficient-cores (18 total) and 18 threads, a 4.2 GHz base clock that boosts to 5.3 GHz, with no integrated graphics, so a discrete graphics card is required. Supplied as the retail boxed version (part number BX80768250KF, EAN 5032037284745); note that unlocked K-series boxed processors do not include a cooler. Typically in stock with fast delivery across Cyprus.

Compatibility — read before you buy
This processor uses the Intel LGA1851 socket and needs a compatible motherboard (Intel 800-series boards only, such as Z890, B860 or H810 — note the new LGA1851 socket is not compatible with LGA1700). It supports DDR5-6400 memory up to 192 GB. The unlocked multiplier allows overclocking on Z-series boards. As an unlocked CPU it ships without a cooler — add a compatible air or liquid cooler.

Frequently Asked Questions

What motherboard do I need for the Core Ultra 5 250KF Plus?
It uses the Intel LGA1851 socket, so it fits compatible boards (Intel 800-series boards only, such as Z890, B860 or H810 — note the new LGA1851 socket is not compatible with LGA1700). A BIOS update may be needed on older boards for newer CPUs. It will not fit other Intel sockets.
Does the Core Ultra 5 250KF Plus come with a cooler?
No. As an unlocked boxed K-series processor it does not include a cooler — you will need a capable air or liquid cooler, especially for sustained turbo and overclocking.
Does the Core Ultra 5 250KF Plus have integrated graphics?
No. This model has no integrated graphics (the "F" suffix), so a discrete graphics card is required to get a display output. CPU performance is identical to the equivalent non-F model.
What is the difference between the Core Ultra 5 250KF Plus and the Core Ultra 5 245KF?
The 250KF Plus is an upgraded refresh: it adds 4 more Efficient-cores (18 cores vs 14), a larger 30 MB cache and higher clocks than the 245KF, while both omit integrated graphics. Arrow Lake P-cores do not use Hyper-Threading, so cores and threads are equal.
Singular Expert Insight
The Core Ultra 5 250KF Plus is the highest core-count "5"-class desktop chip Intel has made — 18 cores (6 Performance + 12 Efficient, no Hyper-Threading) and a 30 MB cache deliver outstanding multi-threaded value for content creation and gaming, with no integrated graphics for buyers who have a discrete GPU. It includes an Intel AI Boost NPU (13 TOPS, an AI PC though below the Copilot+ threshold), is unlocked for overclocking, and as a K-series ships without a cooler. It needs a new LGA1851 800-series board and DDR5. To get the most from it, pair it with dual-channel DDR5 memory and a motherboard that matches your performance and upgrade plans.

Buyer's Guide

Buy it if
You run a discrete graphics card and want class-leading 18-core multi-threaded value with overclocking on the latest LGA1851 platform, plus DDR5 and aftermarket cooling.
Skip it if
You need integrated graphics, are on an existing LGA1700 build, or want the absolute highest gaming FPS per euro from a last-gen chip.
Also consider
The Core Ultra 5 250K Plus (adds Arc graphics), the Core Ultra 5 245KF (cheaper, 14 cores), or the Core Ultra 7 265KF for more performance.
