Intel Ultra 7 265KF Overview

Take your productivity, gaming, and content creation experiences to a new level with the Intel Core Ultra 7 265KF 20-Core LGA 1851 Processor. Designed for professionals and enthusiasts, this desktop processor fits LGA 1851 socket motherboards and delivers improved power efficiency, stability, and performance with its optimized Hybrid Core Architecture, single-thread cores, and integrated NPU. Eight 3.9 GHz Performance-cores power demanding applications while the 12 low-voltage Efficient-cores handle background tasks for smooth multitasking. The built-in Intel Thread Director ensures that the two work seamlessly together by dynamically and intelligently assigning workloads to the right core at the right time.

With 30MB of cache and a 5.5 GHz Turbo Boost Max 3.0 frequency that can be pushed higher with Thermal Velocity Boost technology, this processor is made to handle almost any workload. You can overclock this processor for even greater performance. The Core Ultra 7 265KF also supports PCI Express 5.0 and up to 192GB of dual-channel DDR5 memory at 6400 MHz.

The Core Ultra 7 265KF does not include integrated graphics, meaning that users will need to purchase a separate dedicated graphics card. Please note that a thermal solution is NOT included. This processor is backed by a 3-year warranty.

Hybrid Core Design
Performance-cores provide the speed to handle high-end games and demanding applications while low-priority and background tasks such as streaming video, playing music, and encoding media are handled by the processor's Efficient-cores.
Intel Thread Director
The Intel Thread Director is built into the CPU's cores, working with the operating system to ensure each of the 20 threads are assigned to the right core at the right time.
AI Ready
An integrated NPU can handle up to 13 trillion operations per second (TOPs), providing accelerated performance for AI applications and features.
PCIe 4.0 & 5.0
This processor supports PCIe 4.0 and PCIe 5.0 technologies, providing a combined total of 24 lanes for exceptional data throughput with compatible devices.
Thermal Velocity Boost
Intel Thermal Velocity Boost (TVB) is a technology that unlocks extra CPU performance by pushing the maximum frequency to 5.5 GHz when thermal headroom and turbo power budget are available. It is ideal for burst workloads that have sudden spikes in CPU utilization, providing a temporary performance boost to help avoid slowdowns.
Gaussian & Neural Accelerator
Gaussian and Neural Accelerator 3.5 (GNA) technology helps with noise suppression while enhancing background blurring during video chats.
Intel Deep Learning Boost
Accelerates AI inference to improve performance for deep learning workloads.

Intel Ultra 7 265KF Reviews

Works as expected, OCing clean

By Paul

Works well, no issues. Pushed it pretty hard for a while doing long/large video conversions and a good bit of gaming. Using it with a Gigabyte Z890 motherboard that is doing some basic overclocking and no problems so far. Easy.

Easy Overclocker

Found this processor to be one of the easiest that I've ever overclocked. It's fast, stable, and reliable.
