12th Generation Intel Core desktop processors

When Intel Corp. launched its first 12th Generation Intel® Core™ processors for desktops in late 2021, it unveiled a new processor architecture aimed at delivering the exact computing power you need exactly when you need it. It's a new approach to optimizing CPU performance—and now, there may be no turning back.

For the first time, Intel's top 12th Gen Core chips split the processor into "efficient" cores (E-cores) and "performance" cores (P-cores). It's what Intel calls a "performance hybrid architecture"1, with the efficient cores handle as many basic computing tasks as possible while the performance cores are reserved for more CPU-intensive work. Each new request is intelligently assigned to where it belongs, with Intel promising big benefits for gaming, content creation, and overall productivity.

You'll find 12th Gen Intel Core processors across the Lenovo tower line-up. And there's much more to these popular CPUs than their hyper-productive core structure. There's workload optimization software to steer tasks to the right cores; a big jump in available PCIe lanes (many of them PCIe 5.0); support for new, faster memory technology, and more.

12th Gen Intel Core processor architecture

In a way, 12th Gen Intel® Core™ processors organize their work just like we humans. Most of us try to do our simplest work quickly—often all at once—while giving more time and focus to harder tasks. Similarly, 12th Gen Core chips split your requests between their innovative, purpose-driven cores:

  • Performance cores (P-cores)—Designed to speedily handle single & lightly-threaded tasks that are best kept within a single core.
  • Efficient cores (E-cores)—Designed for highly-threaded workloads that can be shared across multiple cores and be scaled for speed.

Experts call this task splitting and sharing "intelligent workload optimization." Standard OS task schedulers can do some of it, but for its 12th Gen Intel Core processors, the company introduced Intel Thread Director 5.0. It monitors and analyzes real-time performance data to send each application thread to the best available core for that type of work. This helps ensure maximum performance per watt of energy used.2

More PCIe lanes for speedier input/output

At the platform level, 12th Generation Intel® Core™ desktop processors offer multiple innovations that users can feel as they use their PC.

For example, the 12th gen chips offer 20 PCIe lanes—with 16 of them PCIe 5.0, the fastest yet at the time of release. They allow higher-bandwidth peripheral connections to the motherboard, enhancing the performance and responsiveness of everything from discrete graphics to storage drives.

Support for lightning-fast DDR5 memory

Another platform enhancement in 12th Generation Intel Core processors is support for DDR5 memory. And as most PC users know, fast memory can be a game-changer. According to Intel, DDR5 memory can deliver up to 4800 megatransfers per second or MT/s, compared to 3200 MT/s with DDR4.3

If you're unfamiliar with MT/s, it equates to one million transfers per second. It's considered a better way to state memory performance than MHz, which measures memory in terms of the clock cycles of the motherboard.

Overclocking and advanced tuning support

Select 12th Gen Intel® Core™ processors are unlocked, allowing you to unleash additional computing power and performance when needed. Overclocking—which always comes with warnings4—can be useful for gaming, giving you a boost when the competition gets intense. It can also help with tasks like 3D modeling, video editing—anything where you might max-out the processor's typical speed rating.

To help you manage overclocking, 12th Gen Intel Core CPUs provide advanced tuning support through the Intel® Extreme Tuning Utility or Intel XTU. It's software that monitors system performance to help you decide if, and how much, you can overclock.
