Intel Core i9 12900K 3.2GHz (5.2GHz max clock speed), 16 Cores (8 Performance-cores, 8 Efficient-cores), 24 Thread (16 on Performance-cores, 8 on Efficient-cores) CPU, Socket LGA 1700, 30MB SmartCache, 125W TDP, BX8071512900K. Retail box does not include fan, heatsink or thermal paste.
Built for the next generation of gaming.
With the highest clock speeds and a groundbreaking new architecture, you’ll be able to push your gameplay to new heights while secondary apps run seamlessly in the background.
8 on Efficient-cores
Divide and conquer.
Intel’s new performance hybrid architecture integrates two core families into a single CPU, keeping everything in your gaming universe running smoothly.
Prioritises and manages workloads, sending tasks to the best core for the job.3
P-cores are built for performance across single and lightly-threaded workloads, enhancing activities like gaming and productivity.
E-cores are optimised for multi-threaded performance, minimising interruptions from secondary tasks.
Performance beyond the cores.
The new processor architecture is also compatible with the latest platform innovations, giving you performance improvements throughout your PC.
Support for PCIe Gen 5 and DDR5 for high-performance components like memory and graphics.
Thunderbolt™ 4 and Intel® Killer™ Wi-Fi 6/6E (Gig+) deliver fast transfer speeds and connections to peripherals.4
Push past the limit with overclocking.
Increase processing power by fine-tuning your system to run your processor at higher settings2 to improve frame rates and achieve smoother gameplay. Separate overclocking controls for both types of cores gives you nuanced personalisation.
2. Unlocked features are present with select chipsets and processor combinations. Altering clock frequency or voltage may void any product warranties and reduce stability, security, performance, and life of the processor and other components. Check with system and component manufacturers for details.
3. Intel® Thread Director is designed into 12th Gen Intel® Core™ processors and helps supporting operating systems to more intelligently channel workloads to the right core. No user action required. See intel.com for details.
