Intel Ultra 5 250KF Plus Overview

Take your productivity, gaming, and content creation experiences to a new level with the Intel Core Ultra 5 250KF Plus 18-Core LGA 1851 Processor. Built for professionals and enthusiasts, this desktop processor fits LGA 1851 socket motherboards and delivers improved power efficiency, stability, and performance with an updated Arrow Lake architecture, optimized Hybrid Core design, single-thread cores, and integrated NPU. Six 4.2 GHz Performance-cores power applications while the 12 low-voltage Efficient-cores handle background tasks for smooth multitasking.

With 30MB of cache and a 5.3 GHz Max Turbo Boost frequency, this processor is made to handle a variety of workloads. You can overclock this processor for even greater performance. The Core Ultra 5 250KF Plus also supports PCI Express 5.0 and up to 256GB of dual-channel DDR5 memory at 7200 MT/s.

The Core Ultra 5 250KF Plus 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.

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 18 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.
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 Binary Optimization Tool
The Binary Optimization Tool technology increases processor instructions per cycle (IPC) and performance, even if the workload has been optimized for a different x86 processor, game console, or an earlier architecture.
