Intel 12th Gen Core i9 Alder Lake LGA1700 Processors

Featuring 8 performance-cores and 8 efficient-cores, the Intel Core i9 is the best choice for customers looking for Intel’s fastest desktop processor to date!

See also Pentium, Core i3, Core i5, Core i7, Core i9 CPUs.

The 12th Gen Intel Core desktop processors redefine x86 architecture performance. Introducing Intel’s new performance hybrid architecture, combining Performance-cores with Efficient-cores to elevate gaming, productivity, and creation. These breakthrough processors assist the OS in intelligently characterising workloads to ensure optimal core placement for execution and pave the way for future leaps in processor design. Enjoy the full range of the latest platform innovations like industry first PCIe 5.0 readiness and DDR5 memory. With Intel UHD graphics immerse yourself in a visually stunning experience with up to 8K HDR support and the ability to view 4 simultaneous 4K displays. 12th Gen Intel Core desktop processors are available in a wide range of options for maximum flexibility, so you can choose the performance and thermal characteristics you need to game, work, and create like never before.

Breakthrough Core Technology

In a game-changing advance for core performance, 12th Gen Intel Core desktop processors power a revolutionary approach to the x86 architecture. Its Performance-cores—or “P-cores”—are optimised for single and lightly-threaded performance, while its Efficient-cores—or “E-cores”, are optimised for scaling highly-threaded workloads. Intel Thread Director helps to monitor and analyse performance data in real-time to seamlessly place the right application thread on the right core and optimise performance per watt. That means gamers, creators, and professionals can harness both intelligence and power to enhance the experiences that matter most.

Immersive Experiences

Whether you’re delving into the latest gaming titles or focusing on advanced professional applications, 12th Gen Intel Core Desktop processors enable you to immerse without interruptions. Intel UHD Graphics driven by Xe Architecture invite you to take a deep dive into vivid new experiences with enhanced visual support for up to 8K HDR video in billions of colours and up to 4 simultaneous 4K displays. 12th Gen Intel Core desktop processors are capable of cancelling out interruptions with enhanced Gaussian and Neural Accelerator 3.0 (GNA) for more efficient noise suppression and background blurring on video. For elite gaming, world-class productivity, free flowing creation, and more, 12th Gen Intel Core desktop processors enable deep immersion and focus.

Accelerating Platform Innovation

Tap into the latest platform technologies that drive incredible gaming, workflow, and creation. The 12th Gen Intel Core desktop processors offer up to 20 lanes (16 PCIe 5.0 and 4 PCIe 4.0) to drive optimal discrete graphics and storage performance by enabling higher bandwidth connection points. DDR5 brings fast speeds up to 4800 MT/s, this allows for increased memory bandwidth speeds compared to previous generations that use DDR4 3200 MT/s memory. Fine tune both compute power and performance with unlocked (K-Suffix) 12th Gen Intel Core desktop processors that have overclocking capabilities and Advanced Tuning support via Intel Extreme Tuning Utility (XTU). With these and other platform enhancements you’ll be able to work, game, and create with impressive control and confidence.
