Intel Alder Lake: 12th Generation Core Mobile and Desktop Processors

Intel Alder Lake 12th Gen Processors

12th Generation Intel Core Processors:
Delivering Superior Performance Where You Need It Most

Take the next evolutionary leap with the performance hybrid architecture of 12th Generation Intel Core processors. Get the performance you need, where you need it—whether you’re a creator, developer, streamer, or everyday user. Whatever you’re into, do more of it, whenever you want.

Superior Performance When You Need It. Multitasking Like You’ve Always Wanted.

12th Gen Intel Core processors—a generation like no other before it. With unprecedented new performance hybrid architecture, 12th Gen Intel Core processors offer a unique combination of Performance and Efficient-cores (P-core and E-core). And that means real-world performance, intuitively scaled to match whatever you’re doing.

The Performance-core is Intel’s highest performing CPU core ever. And it’s designed to maximize single-thread performance and responsiveness for compute intensive workloads like AI and 3D design. The Efficient-core delivers multithreaded performance for tasks that can run in parallel (like image rendering), along with efficient offload of background tasks for modern multitasking.

So that Performance-cores and Efficient-cores can work seamlessly with the operating system, Intel built Intel Thread Director right into the hardware. Automatically monitoring and analysing on-the-fly, Intel Thread Director guides the operating system, helping it place the right thread on the right core, at the right time. And it does it all dynamically, adapting scheduling guidance based on actual computing needs, not on static rules.

12th Gen Intel Core processors support the next wave of discrete graphics cards and storage devices. These devices take advantage of increased throughput coming with PCIe 5.0 as well the higher speeds and bandwidth of DDR5 memory.

Another standard feature of 12th Gen Intel Core processors: Intel Wi-Fi 6E (Gig+). Offering exclusive, high-speed channels that other legacy devices simply can’t, Intel Wi-Fi 6E lets you experience nearly 3x faster connectivity without the interference. And that means more freedom to work or learn from home—or relax with super-smooth, high-quality streaming.

You can also connect your PC to multiple 4K monitors and other accessories, all with one reversible cable. The 12th Gen Intel Core processor family—our most innovative platform yet—enables Thunderbolt 4, the simplest, fastest, most reliable port available.

With 12th Gen Intel Core processors, standard, built-in features enable capabilities like noise suppression, auto-framing, and optimization for bandwidth and video resolution. That saves you time and lets you multitask in ways you’ve only ever dreamed of—until now.

Alder Lake-S vs Alder Lake-P

Alder Lake-P

Alder Lake-P parts will include all SKUs that used to be in the U and H subfamilies. Higher-end mobile parts will have 6 P-cores and 8 E-cores, while low voltage parts will combine two P-cores and 8 E-cores. All Alder Lake-P processors will be paired with an Intel Xe graphics engine with 96 execution units.

Alder Lake-S

Alder Lake-S processors are aimed at enthusiasts and will feature up to 8 P-cores and 8 E-cores, while mainstream and lower-end variants will only have P-cores. Either way, they’ll all come with an Intel Xe integrated graphics engine with 32 execution units.

Only the L3 cache is shared across P-cores and E-cores to allow them to operate separately depending on the workload that’s thrown at them. Intel has chosen to keep the instruction sets all the same for both types of cores, with the notable exception of E-cores, which won’t support AVX512 workloads due to their current architecture. This also means that if a laptop or desktop PC manufacturer chooses to enable E-cores, AVX512 will be disabled on P-cores.
