Cores at work

Intel's new high-performance hybrid architecture integrates two core families into one processor for a smoother gaming experience. Intel Thread Director prioritizes and manages workloads by determining which core is best suited for each task. Performance cores are designed for unique, low-thread count workloads, enhancing activities such as video gaming or productivity tasks. Efficiency cores are optimised for multi-threading by reducing interruptions from secondary tasks.

Reach new heights

With high frequencies, achieve high performance in games. Confidently take on your opponents or explore new worlds with a revolutionary processor architecture that focuses on what matters. Intel 12th generation processors are simply designed for the next generation of gaming.

    Excellent!

    Very good processor coupled with a 3080, with a slight preference for the Ryzen 9 when it comes to multitasking, but when it comes to gaming I'm sticking with Intel!

    A real monster

    Great for MFS coupled with a 3080ti it sends out the pater
    Heats up no more than that with a WaterCooling and the heat wave
    For gaming just the top of the line not finding any games that make it bend
    Score 3DMArk 18 057

    Amazing

    Excellent processor, very powerful!
    No worries on the processor, just the temperature, take a good watercooling.
    My processor is mounted on a MSI MAG Z690 Torpedo DDR5 motherboard with 32GB of 4800MHz ram coupled with a NZXT Kraken x73 for cooling and it's just, excellent!
    In games, set to ultra with an RTX 3080, the processor does not go above 60/65 degrees
    Go ahead and close your eyes!
