The Intel Core i5-2500K Processor has an unlocked core allowing for overclocking.
Quad-Core Processor Running at 3.30 GHz for Fast Performance

The Intel Core i5-2500K has four processing cores running at 3.30 GHz. It features a 6 MB L3 shared cache that is dynamically allocated to each processor core, based on workload. This reduces latency and improves performance.

Additionally, the i5 comes with Advanced Vector Extensions, a set of instructions to improve software performance for intensive applications like audio processing, audio codecs, and image and video editing applications.

Fully Unlocked Core for Overclocking

The Core i5-2500K is fully unlocked, allowing gamers and enthusiasts to overclock the processor for faster performance. With a fully unlocked processor, you can independently raise clock speeds without impacting other system components.

Turbo Boost for Extra Processor Speed

The i5-2500K features Intel Turbo Boost Technology 2.0, which delivers a burst of processor speed automatically when the workload demands additional performance. The technology dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom when operating below specified limits. The result is adaptive performance that's more intelligent and energy efficient.

Built-In Visuals Provide Rich, Steady Graphics

The built-in visuals of the Intel Core i5-2500K deliver a seamless graphic experience when you're viewing and manipulating pictures and media on your PC. They also eliminate the need for a discrete graphics card, reducing power consumption and system cost.

Intel Quick Sync Video enables quick conversions of video files for portable media players or online sharing. Experience sharp images and rich color with Clear Video Technology, which provides visual quality and color fidelity enhancements for vivid high-definition and Blu-ray playback. Intel HD Graphics offers enhanced 3D performance for immersive mainstream and casual gaming without hesitations or interruptions.

The Core i5 is also equipped with Intel InTru3D, which provides stereoscopic 3D Blu-ray playback in full 1080p resolution and premium audio via HDMI 1.4.

Intel Virtualization Technology

Intel Virtualization Technology allows multiple "virtual" environments to function on one hardware platform. It offers improved manageability, limiting downtime and maintaining productivity by isolating computing activities into separate partitions.

Optimized for Energy Efficiency

The Core i5 is designed to optimize every watt of electricity, resulting in a more energy-efficient system that is cooler and cheaper to run. In a system with other energy-efficient components, the processor can meet Energy Star specifications.

What's in the Box

Intel Core i5-2500K processor, fan/heat-sink cooling solution, warranty booklet, and Intel Inside logo label.
