Intel Core Ultra 5 245KF Unlocked Desktop Processor

Core Ultra Series 2 Arrow Lake · FCLGA1851 · Boxed (no cooler)
14-Core 14-ThreadUp to 5.2 GHz24 MB Intel Smart Cache CacheUnlocked

The Intel Core Ultra 5 245KF is a Core Ultra Series 2 (Arrow Lake) desktop processor with 6 Performance-cores + 8 Efficient-cores (14 total) and 14 threads, a 4.2 GHz base clock that boosts to 5.2 GHz, with no integrated graphics, so a discrete graphics card is required. Supplied as the retail boxed version (part number BX80768245KF, EAN 5032037282109); 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 245KF?
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 245KF 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 245KF 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 245KF and the Core Ultra 5 245K?
CPU performance is identical — 14 cores (6P+8E), 14 threads, up to 5.2 GHz, unlocked. The 245KF removes the integrated Intel Arc graphics for a slightly lower price and requires a discrete GPU. Arrow Lake P-cores do not use Hyper-Threading, so cores and threads are equal.
Singular Expert Insight
The Core Ultra 5 245KF is Arrow Lake’s value enthusiast chip without integrated graphics — 14 cores (6 Performance + 8 Efficient, no Hyper-Threading) deliver strong multi-threaded productivity and gaming with low power and heat, for buyers with a discrete GPU. It still includes an Intel AI Boost NPU (13 TOPS, an AI PC though below the Copilot+ threshold). It needs a new LGA1851 800-series board and DDR5, and as a K-series ships without a cooler. 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 an efficient, modern unlocked 14-core CPU on the latest LGA1851 platform at the lower KF price, with DDR5 and aftermarket cooling.
Skip it if
You need integrated graphics, are on an existing LGA1700 build, or want the highest gaming FPS per euro from a last-gen chip.
Also consider
The Core Ultra 5 245K (adds Arc graphics), the Core Ultra 7 265KF (more cores), or the i5-14600KF on LGA1700.
