Overview

New hybrid architecture for optimal performance

With the Alder Lake processors, Intel has launched a small revolution in the world of x86 architecture by adopting a hybrid technology based on two different types of cores assembled within the same chip: Performance-Cores and Efficient-Cores. With more cores and more power, 12th generation Intel processors are ready for next-generation gaming, PCI-Express 5.0 graphics cards and DDR5 RAM.

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.

    best processor

    very good processor i recommend it you can launch star citizen which is a game that takes resources from the processor and not the graphics card

    Intel's performance continues to improve.

    Fast, secure delivery, a high-performance processor that doesn't overheat, what more could you ask for?

    Wow!

    Delivery: perfect (as usual!)
    Disassembled baby, almost all parts still working .... (the motherboard was starting to fail) ... I opted for this configuration which may not be the best of the best, but which suits me perfectly for studio work ... and with a good reorganization of my case I went from a consumption in idle of 230W to a consumption of 83W ... but when you work on Premiere Pro it is really worthwhile to rely on NVMe in PCIe 4.0 Gen4 .... it's a bit more powerful than SSD in SATA 3 ... I'm very happy with the service and the quality of the product.

    easy installation, great cpu

    well advised for cpu/fan/motherboard compatibility! I took this model for c++ development.

    Latest generation processor that does its job very well

    The power is there with this latest generation Cpu. 16 cores are ideal for running all applications, virtualization and gaming. On a Z690 motherboard and DDR5, it's a perfect combo.

    Please note that this model does not include a GPU (as stated in the product sheet). A video card is needed to complete the system.

    Furthermore, a substantial fan is also necessary (I chose a Noctua NH-D15) to avoid overheating.

    I haven't tested the OC yet but I'm not too worried about it.
