Intel Core Ultra 5 250KF Plus Unlocked Desktop Processor

Core Ultra Series 2 Plus Arrow Lake Refresh · FCLGA1851 · Tray / OEM
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 a tray / OEM unit (part number AT807683B9B4887) without a bundled 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 a tray unit it ships without a cooler — add a compatible 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. This is a tray / OEM unit supplied without a cooler, so budget for a compatible air or liquid cooler.
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 250K Plus?
CPU performance is identical — 18 cores (6P+12E), 18 threads, up to 5.3 GHz, unlocked. The 250KF drops the integrated Intel Arc graphics for a lower price and requires a discrete GPU. Arrow Lake P-cores do not use Hyper-Threading, so cores and threads are equal. This is the tray/OEM unit, supplied without a cooler.
Singular Expert Insight
The Core Ultra 5 250KF Plus is the highest core-count "5"-class desktop chip Intel has made, minus the graphics — 18 cores (6 Performance + 12 Efficient, no Hyper-Threading) and a 30 MB cache deliver outstanding multi-threaded value for buyers with 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 this tray/OEM version ships without a retail box or cooler. It needs a new LGA1851 800-series board with 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, and you have a cooler at the lower tray price.
Skip it if
You need integrated graphics, want a boxed unit with a cooler, or are on an existing LGA1700 build.
Also consider
The Core Ultra 5 250K Plus (adds Arc graphics), the boxed 250KF Plus, or the Core Ultra 5 245KF (14 cores, cheaper).
