INTEL CORE ULTRA 5 - 245KF 14-Core LGA 1851 Gaming Processor

Power your productivity, gaming, and content creation experiences with the Intel Core Ultra 5 245KF 14-Core LGA 1851 Processor. Designed for content creators and gamers, this 15th generation 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. Six 4.2 GHz Performance-cores drive demanding applications while the eight 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 24MB of cache and a 5.2 GHz Turbo Boost Max frequency that can be pushed higher with Thermal Velocity Boost technology, this processor is made to handle a variety of workloads. You can overclock this processor for even greater performance. The Core Ultra 5 245KF also supports PCI Express 5.0 and up to 192GB of dual-channel DDR5 memory at 6400 MHz.

The Core Ultra 5 245KF 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 14 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.
