Today, the 12th generation Core officially lifted the ban. This time, the flagship model of the 12th generation Core is Core i9-12900K. This processor uses 10nm technology, adopts a hybrid architecture design for the first time, and has 16 cores and 24 threads. In addition, the 12th generation Core also supports DDR5 and PCIe 5.0 technology. PCIe 5.0 has no corresponding product at present, but DDR5 memory is in place. Today we will use Gigabyte Z690 AORUS MASTER a main board (referred to as Gigabyte Super Sculpture Z690), combined with DDR5 memory, forms a platform to witness the real performance of the Core i9-12900K.

01 Introduction to Core i9-12900K

Before the evaluation, let's introduce the 12 generation flagship Core i9-12900K processor in detail. This processor has 16 cores and 24 threads, including 8 Performance Cores that support hyper threading, and 8 Efficiency Cores that do not support hyper threading. Up to 5.2GHz under the frequency of Intel Remax Max Technology 3.0. The highest frequency of the performance core is 5.0GHz, and the highest frequency of the energy efficiency core is 3.9GHz. The UHD 770 core graphics card is integrated.

Core i9-12900K

Performance core and energy efficiency core are the new hybrid architecture design brought by Intel for the 12th generation Core, that is, the big and small core design. The processor will consist of a performance core P-Core and an energy efficiency core E-Core. The performance core P-Core uses Golden Cove micro architecture, and the energy efficiency core E-Core uses Gracemont micro architecture. The performance core P-Core supports AVX-512 and DLBoost deep learning acceleration, and supports hyper threading, up to 8 cores and 16 threads. However, the energy efficiency core does not support hyper threading. It can have 8 cores and 8 threads at most, so the last number of cores of the Core i9-12900K is 16 cores and 24 threads.

The design of Intel's large and small cores is fundamentally different from that of mobile phone's large and small cores in terms of power saving and power consumption. The purpose of energy efficiency cores is to strengthen performance cores. The performance core is mainly for single threaded and high load games and productivity Software For applications, the energy efficiency core is for multi-threaded optimization, mainly for background processes. In practical applications, the background processes are mainly processed by the energy efficiency core, so that the performance of the foreground performance core can be fully exerted.

At the same time, Intel also said that the Windows 11 system can maximize the performance of the 12th generation Core, because Intel has introduced thread scheduler technology for the 12th generation Core. Only under the Windows 11 system can the large and small cores ensure more accurate scheduling and allocation. At the same time, this distribution and scheduling logic is managed by the micro controller integrated by the 12th generation Core, which will cooperate with the system and adjust itself without manual operation by the user.

Core i9-12900K

In addition to the size core, the 12th generation Core introduced DDR5 memory and PCIe 5.0, one step ahead of AMD. DDR5 memory adopts new protocols and specifications. A single memory can realize dual channels, and two can form four channels. The product capacity starts from 8GB, and the frequency starts from DDR5-4800. PCIe 5.0 has no actual product yet, and it is a technology for the future.

Double four channels

Double four channels will undoubtedly give the platform stronger performance, whether AIDA64 The memory score is still better in the game test of Tomb Raider: Shadow. The four channels have better performance, plus the higher speed brought by DDR5. If you are a hardware enthusiast, it is recommended that you choose Gigabyte Super Sculpture Z690 motherboard with four channels of DDR5 to form a platform.

Copying test

Finally, we will give you a copy machine test. This time, we use AIDA 64 single copy FPU, which is more stressful than double copy CPU and FPU, and also eats the heat dissipation performance of the motherboard. If the heat dissipation level of the motherboard is not up to the standard, even the 360MM cold exhaust can hardly hold down the Core i9-12900K.

Copying machine

After 20 minutes of copying, the core temperature of Core i9-12900K is about 89 ℃, most of which are performance cores at more than 80 ℃, and energy efficiency cores at more than 70 ℃. The temperature performance of the whole machine is good, and there is no direct 100 ℃ frequency reduction. The third-generation stack cooling fin of Gigabyte Super Sculpture Z690 motherboard is not a false name. The powerful cooling effect enables the stable operation of CPU under high load power supply, which is enough to support the high voltage demand of Core i9-12900K.

04 A new era is coming

Intel, which has squeezed several generations of toothpaste, finally came up with some hard goods. The performance of the 12th generation Core is obvious to all. It is no problem to say that the Core i9-12900K is the most powerful consumer processor on the desktop at present, and it completely surpasses the AMD Reelong 5000 processor in both benchmark tests and field tests.

Of course, there is nothing too proud of the cross era fight, but in addition to performance, the 12th generation Core has also brought DDR5 and PCIe 5.0 to the DIY market. DDR5 has raised the performance limit of the 12th generation Core, making it possible for processors to pursue higher performance. Although PCIe 5.0 was not launched, it can bring higher I/O throughput and will greatly improve the expansion capability of the whole machine in the future. With the blessing of two new ecosystems, the level of hardware will continue to improve in the future.

If you want to experience the powerful performance of the 12th generation Core, you can't do without the support of the Z690 motherboard. The overall specifications and materials of this generation of Z690 motherboard have been further upgraded. As can be seen from the Gigabyte Super Sculpture Z690 motherboard we tested, the core power supply specification of this motherboard is up to 19 phases, and the single phase power supply is 105A. The total power supply has reached 1995 A, Such a powerful power supply system and the excellent cooling technology supported by this motherboard can give full play to the performance of the Core i9-12900K.

At present, Gigabyte Super Sculpture Z690 motherboard and Core i9-12900K have been launched. With DDR5 memory, the cost of other hardware is close to 10000 yuan, which is expensive.
