The world’s fastest desktop processor.1
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.4
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.5
Do you work with video?
Intel® Quick Sync Video uses the dedicated media processing capabilities of Intel® Graphics Technology to decode and encode fast, enabling the processor to complete other tasks and improving system responsiveness.
