[Bestbuy618DIY Hardware Channel]Intel officially released the 12th generation of Intel Core series processors on October 28. The official claim is that the unlocked processor with the new Intel high-performance hybrid architecture is all sound and uncompromising, whether playing games or multitasking. The official also shouted the slogan of the 12th generation Intel Core Heterogeneous One Battle to seal the gods, so how does it perform in the end? Can it be a god? Let’s take a look.
This is the first time an X86 processor has been designed with a hybrid architecture! Additionally, the process technology has been increased to 10nm, and the 12th generation Core has added support for the PCi-E 5.0 protocol and DDR5 memory.
The new Alder Lake architecture is used in the 12th generation Intel Core processors, which is the first processor to use Intel 7 (10nm) process technology, bidding farewell to the 14nm that has been with us for many years. We have finally waited for a new outbreak of Intel processor performance. In comparison to the previous generation, the process process has been improved while stuffing more cores, which not only effectively controls heat but also brings significant performance improvement. The 12th generation Intel Core processors have taken a disruptive approach to the x86 architecture, which is a hybrid architecture design.
There are two types of CPU cores: performance and energy efficiency. The first thing that came to mind when I heard this concept was the traditional big.LITTLE size core architecture that has been used on cell phones, but Intel made it a point to emphasize that this is very different from the traditional big.LITTLE size core architecture on smartphones, because the small core in the size core is to save energy and power, and the E core in the 12th generation Core is to strengthen the multi-core performance, and simply looking at its performance is impressive.
Single-threaded or lightly threaded workloads are supported by Performance Cores (PC). The design is a continuation of Intel’s legacy design and is a continuation of the Core family, optimized for single- and light-threaded performance for higher-load gaming and productivity applications, with up to eight in the P1 series of desktop products and up to six in the P2 series. The design is more akin to the Atom Atom family, which is optimized for multi-threaded performance and has the least impact on front-end task management, with up to 8 in the desktop P1 series and none in the P2 series.

Comet Lake employs the classic Sky Lake architecture, which has been used in multiple generations of products. As shown in the chart, the new Efficient Cores are already comparable in terms of performance to Sky Lake’s architecture.
Performance and efficiency cores are continuously optimized for performance-to-power ratio via Intel Thread Director, which monitors and analyzes performance data in real time to accurately assign application threads to the matching cores. As a result, gamers, creators, and professionals can fully utilize this intelligent feature and superior performance to effectively enhance their experience.
Intel also demonstrated the Intel Hardware Thread Scheduler (Intel Thread Director) in action. It can assist the operating system in implementing a new thread scheduling mechanism with nanosecond-level monitoring of the Runtime instruction set, as well as having a Runtime response mechanism that can provide timely feedback to the operating system on instructions and kernel operation status. There is also a scheduling guide that provides dynamic scheduling guidelines based on heat dissipation, operational status, and power settings.
The introduction of these features has completely changed the traditional way of communication between the OS and CPU. Intel and OS vendors are collaborating to promote this new thread scheduling mechanism, and the latest Windows 11 fully utilizes Intel’s hardware thread scheduler to achieve a more reasonable allocation of threads in a hybrid architecture, demonstrating a more efficient and intelligent thread allocation logic.
The first round of 12-generation Intel Core processors were released in six models: i9-12900K/KF, i7-12700K/KF, i5-12600K/KF, and i7-12700K/KF. Each processor’s specifications are shown below.
The Core i9-12900K and i5-12600K processors are being tested.
