Intel Core Ultra 7 265KF Unlocked Desktop Processor

Core Ultra Series 2 Arrow Lake · FCLGA1851 · Boxed (no cooler)
20-Core 20-ThreadUp to 5.5 GHz30 MB Intel Smart Cache CacheUnlocked

The Intel Core Ultra 7 265KF is a Core Ultra Series 2 (Arrow Lake) desktop processor with 8 Performance-cores + 12 Efficient-cores (20 total) and 20 threads, a 3.9 GHz base clock that boosts to 5.5 GHz, with no integrated graphics, so a discrete graphics card is required. Supplied as the retail boxed version (part number BX80768265KF, EAN 5032037281980); 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 7 265KF?
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 7 265KF 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 7 265KF 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 7 265KF and the Core Ultra 7 265K?
CPU performance is identical — 20 cores (8P+12E), 20 threads, up to 5.5 GHz, unlocked. The 265KF 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 7 265KF is Arrow Lake’s high-value performer minus the integrated graphics — 20 cores (8 Performance + 12 Efficient, no Hyper-Threading) deliver excellent multi-threaded work and gaming with much lower power and heat than the i7-14700KF, for buyers who already have 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 20-core CPU with overclocking on the latest LGA1851 platform at a lower price than the 265K.
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 7 265K (adds Arc graphics), the Core Ultra 9 285K (more cores), or the i7-14700KF on LGA1700.
