The 12th generation Core is the biggest revision of Intel in the past ten years. Whether it is the architecture or the I/O specification, it has taken a very big step. Whether you are an AMD fan or a follower of Intel, the 12th generation CPU is necessary You are very noteworthy, because Intel's move this time is not inferior to the challenges brought by the Zen architecture.
1. What is the difference between the 12th generation Core and the 11th generation?
1. This means that Intel's latest generation of processors will use a 10nm process, which will have higher transistor density, lower power consumption, and better performance than the previously used 14nm process. At the same time, this also means that Intel's CPU pins will be changed from the previous LGA 1200 to LGA 1700, which will require users to purchase a new motherboard to support the new processor. This change is expected to bring better performance and greater efficiency to users, while also laying the groundwork for future technological developments.
2. A brand-new Alder Lake architecture, which for the first time introduced the size core design scheme on the X86 software.
3. Fully evolved I/O specification model, suitable for the latest DDR5 running memory and PCIe 5.0.
4. The specification model of the core graphics card has been upgraded to UHD 770.
2. What are the specifications of the Intel 12th generation Core first launch model?
There are 6 models and specifications of the 12th-generation CPU launch this time, as shown in the figure below. There are 2 types of i5, i7, and i9 each, and the suffix F means that there is no embedded core graphics card.
3. What is the difference between the 12th generation Core and the 11th generation? (detailed)
1. 10nm process technology, LGA 1700 socket
Intel's 12th generation CPU is manufactured using the Intel 7 fabrication process, which represents an improvement over the previous 10nm process, known as 10nm Super Fin. The Intel 7 process boasts a higher crystal relative density, which translates to improved performance and power efficiency in chip architecture design. While Intel 7 is technically based on the 10nm process, its introduction marks the end of the era of 14nm process technology in the desktop computing space, representing a significant milestone for Intel's desktop service platform. Overall, the adoption of Intel's 12th generation CPU brings about higher efficiency, superior performance, and an enhanced user experience.
The 12th generation CPU replaces the socket with LGA 1700, which has 500 more contact points than the 10th generation LGA 1200. Therefore, the 12th-generation CPU must be matched with a new 600 series chipset motherboard, and the fasteners of the CPU radiator must also be compatible with LGA 1700.
2. New upgrade of I/O
The biggest feature of intel's 12th generation CPU depends on its I/O update. The 12th generation of Alder Lake may support DDR5 memory and PCIe 5.0, which is considered a full rhythm for Intel. It is predictable to switch from DDR4 to DDR5, because DDR4 has been used for many years after all, but Intel’s leap from PCIe 4.0 to PCIe 5.0 is unexpected, but there are no products for PCIe 4.0 yet How popular is it, and even if your new graphics card supports it, even PCIe 3.0 can completely serve as the current popular independent graphics card. This time, Intel's PCIe span to 5.0 is to lay the foundation for other PCIe configurations, not just Only for discrete graphics cards. Although it seems a bit too advanced now, it plays a very, very important role in the acceleration of PCIe expansion equipment in the future.
The 12th generation of Alder Lake supports the latest DDR5 memory, but it has not withdrawn its support for DDR4 memory, so two versions of motherboards supporting DDR4 and DDR5 will be released on the market for consumers to choose from.
3. Size core design scheme
This Alder Lake will have a maximum of 16 keys, 24 processes and a 30MB L3 cache. Many people may be confused when they see this specification model for the first time. Why are 16 keys 24 processes? Why not 32 processes?
Because this time Alder Lake adopts the Hybrid Croe (hybrid core) design, there will be two cores in the CPU at the same time, each of which is a Performance Core (commonly known as a large core of P-Core) with excellent performance and low latency; Consumption of Efficient Core (commonly known as E-Core flower core). Each large core has 2 processes, while the flower core has only 1 process. Taking the highest specification c9-12900k as an example, it is composed of 8 large cores and 8 small cores, so it has 16 cores and 24 processes.
But the design of this size core is not something new, because Apple's M1 is the hybrid core used, it has long been widely used on ARM architecture CPUs, but this time Intel has designed this hybrid core For the first time, it was applied to the CPU of the X86 architecture.
In essence, the large-core P-Core is equivalent to the cpu core in our traditional cognition. It has strong performance and can be used for playing games, doing main work, and used in most high-load applications; while the small-core The E-Core has an excellent power consumption ratio and can be used to solve some tedious and complicated tasks. It seems that some system software background applications can replace P-Core for processing, so that P-Core can be dedicated to these applications that must have excellent performance. Realize excellent division of labor.
4. The core graphics card model specification is upgraded to UHD 770
Regarding how much the performance of the core display has improved, I will give you a separate detailed introduction during the actual evaluation of the 12th generation CPU.
4. How big is the performance improvement of the 12th generation CPU?
According to Intel’s official website, compared with the previous generation of Cypress Cove, the P-Core with excellent performance has a 19% increase in versatility; the low-energy E-Core has a 40% increase in performance compared with Sky Lake at the same output power, and How many 4 E-Cores can be packed into the core space of 1 Sky Lake.
What's new in Gen 12?
A lot has changed in Generation 12. One thing is that we'll see improvements across the board in terms of trim. As you'll see later, there are a lot of notable improvements, pruned one by one. Here's what's new in Gen 12.
DDR5 memory
DDR5 is the next generation of memory chips that will power the next wave of computing. The 12th Generation Intel Core processors are the first to use DDR5, which promises to pack more features into smaller packages.
DDR5 is a type of RAM (random access memory) that you might find in a computer or mobile device. It stores temporary data while your device is running software and performing tasks. Here's what you need to know about DDR5:
DDR5 memory offers more bandwidth than DDR4. That means it can move data faster between the processor and memory slots on the motherboard, and between the processor and the graphics card or other device plugged into the computer. This makes it ideal for rendering graphics, playing games at high resolution, generating complex 3D models, or editing large video files with multiple audio tracks.
PCIe 5.0 support
With the release of Intel's 12th generation processors, the company upped the PCIe standard to 5.0, ushering in a new era of ultra-fast memory support, which means more bandwidth for graphics cards and other components using the standard.
While the upgrade isn't as big as it sounds - 5.0 is just an incremental improvement over 4.0 - it does mean that future graphics cards will get more bandwidth for better performance at higher resolutions and frame rates.

This may be especially important for gamers who want to run multiple high-resolution monitors or use multiple graphics cards at the same time, because they don't have to worry about bottlenecking the system with older hardware with lower bandwidth limitations (such as 4× PCIe 3.0) .
TDP (Thermal Design Power) and PBP (Processor Base Power)
12th Gen Intel Core processors have a TDP of 45W. This is the maximum power the processor can consume while performing intensive tasks such as gaming or streaming 4K video. On the other hand, PBP (Processor Base Power) is the lowest power a processor can consume.
Why is this important? Well, if you're using a laptop with a battery that supports fast charging, you'll want to make sure your processor has a low PBP rating so it doesn't charge too fast and drain the battery prematurely.
