The DRM problem of the 12th generation Core is in the direction of solution.What is the reason why Alder Lake that Intel developers talk about the game?
Shalev is a person who has led the development of the desktop PC version ALDER LAKE on Intel's Development Team in Haifa, Israel.
In the interview, the opening of the opening is, "Our 12th generation Core processor desktop PC version is proud to be the best gaming PC CPU, and the first product that adopts a hybrid architecture for the mainstream CPU.He was convinced that it would be a revolutionary product that would change the history of the X86 CPU in the future, "he emphasized that the products of competitors were exceeded in performance.
Regarding the performance, the following review articles are published in this magazine, so please refer to that.In fact, it is generally exceeded or exceeds to competitors.

The secret of Alder Lake's high performance lies in Charlev's "Hybrid Architecture."In fact, this is not the first time that Intel introduced a hybrid architecture.
Developed code name Lakefield "Intel Core Processors with Hybrid Technology", two types of CPU core (EFFICIENCY core, 4XATOM processor), pc core (Performance core, 1XCore processor) and E -core (EFFICIEN Core Processor).Because it is done.

When performance is needed, switch to P core and execute, and in some cases, use all e -core to improve performance.On the other hand, when you want to reduce power consumption to the limit, such as when idle, turn off the P core and execute only with e -core.ARM architecture CPU is big.It can be said that the idea of Little minimizes power consumption during idle idle.
This is also possible for the 12th generation Core hybrid architecture, but it is a big difference that the main focus is placed in "processing capabilities", reflecting the products for PCs.As described in the following article, Alder Lake's CPU core is GOLDEN COVE for GRACEMONT for P Core.

To put it simply, Golden Cove is based on the flow of Sunny Cove, which was adopted in the 10th generation Core (ICE LAKE), and is positioned as the successor to WiLLOW COVE, which was adopted in the 11th generation Core (Tiger Lake).。It can be said that it is a CPU core that realizes high single -sled performance that realizes low latency.
On the other hand, Gracemont, which was adopted in the E -core, is an atom -based core.As a result, the power efficiency is better than the Cove system, and the 4 -core GRACEMONT has reduced the power consumption by 80%while achieving the same performance as the sixth generation Core (Skylake) with a two -core configuration.
PコアとEコア(出典 : 12th-Gen-Blueprint-Series-Presentation、Intel)Intel is characterized by using the e -core to improve the performance at the time of multi -thread.
"P core was designed to execute the foreground task at high performance, on the other hand, to make the background task efficiently and to process multi -thread more efficiently.It is designed.
Intel Thread Director exists to utilize these two types of cores, providing hints to execute Windows 11 more efficiently, to cooperate with the OS to customers with the best user experience.Can be provided. "
The P core is used to operate apps that are run in the foreground, such as a single -threaded application, such as Word and Excel, such as Word and Excel.
E -core, on the other hand, is executed by assigned an app that keeps moving in the background (that always communicates with the cloud, such as Skype or Slack) or when multi -threaded.
It is Intel Thread Director that coordinates those tasks in cooperation with the OS scheduler.The function is constantly monitoring the inside of the CPU, and the operation status is passed as a hint to the OS scheduler.At present, only Windows 11 is supported.
If you do not have Intel Thread Director, multi -threaded multi -thread processing that can be performed more efficiently by E -core will be assigned to the P core.
In particular, old apps do not know the existence of hybrid architectures, so they try to force all CPU core execution.Even in such an old app, the successful assignment is the role of Intel Thread Director.
When Apple's M1 appeared, the benchmark score due to the high multi -thread performance was shocking, but if you look closely, the performance of the single thread is too 11th generation Core (Tiger Lake).It didn't change.
Speaking of where between M1 and Tiger Lake, the use of E -core during multi -thread in the E -core (high -efficiency core) has a major impact.Therefore, it can be said that if E -core is used in multi -thread processing at the benchmark even in Intel's 12th generation Core (Alder Lake), it will lead to significant performance improvement.
