After the release of the desktop version of Alder Lake-S for the 12th generation Core processor last October, Intel regained the attention of gamers and hardware enthusiasts in the DIY market with its outstanding product power. In 2022, Intel is further junior, releasing a mobile version of the 12th generation Core processor at CES 2022.
Intel says the architecture of the 12th Generation Core processor is well designed to be scalable and accommodate all types of notebook products. Specifically, it includes the high-performance mobile version of the 45W H series for game books, which is commonly known as the standard pressure, and the 28W P series for performance-level thin and light books, as well as the 15W and 9W U series for ordinary thin and light books.
Intel highlighted the Alder Lake-H high-performance mobile version at the CES 2022 exhibition, and the majority of OEMs have also released new game products. This allows us to experience the true performance of a new generation of processors through actual measurement.
Before testing begins, let's briefly introduce the basic features of the 12th generation Core processor high-performance mobile version of Alder Lake-H. Alder Lake-H uses the Intel 7 process (previously known as 10nm Enhanced SuperFin) and applies a Hybrid hybrid architecture design, commonly known as "size core", which provides up to 6 Golden Cove microarchitecture P-Core + 6 Gracemont microarchitecture energy efficiency cores, and can be operated in a Windows 11 system environment through ITD for hardware-level scheduling Peripherals: Alder Lake-H's memory controller supports DDR5-4800 and LPDDR5-5200, and is also compatible with the previous generation of DDR4-3200 and LPDDR4x-4266, depending on the OEM's motherboard design; supports PCIe 4.0×8 for connecting discrete graphics cards, two sets of PCIe 4.0×4 for connecting SSDs; Thunderbolt 4 controllers also integrate 4 direct connections; chipsets The CNVIo module of the Wi-Fi 6E network has also been inherited, and there are also additional PCIe 3.0×12 channels, etc.
In terms of specific product parameters, the 12th generation Core processor high-performance mobile version of Alder Lake-H also contains three major product families of Core i9, Core i7, and Core i5, of which core i9-12900HK and Core i9-12900H specifications are 6P-Core+8E-Core with a total of 24 threads, a three-level cache capacity of 24MB, The highest single-core turbo frequency is also 5.0GHz, the only difference is that the HK suffix unlocks the overclocking, you can manually adjust the processor's core multiplier and memory frequency and other parameters in XTU, while the ordinary H suffix products, including the Core i9-12900H, are completely locked in the frequency.
Introduction to the test platform
At present, the PConline review room has received a ROG Gun God 6 game book, which has just been launched with a Core i9-12900H processor, equipped with 32GB of DDR5-4800 dual-channel memory, and RTX 3070 Ti laptop GPU, basically all hardware configurations are up to date. In addition, this game can also provide a strong heat dissipation ability, single baking can be stable at more than 90W for a long time, can make the performance of the processor fully released.
Taking this opportunity, we will use the ROG Gun God 6 game book as a test platform to fully demonstrate the performance of the Core i9-12900H.
If you want to fully understand the information of ROG Gun god 6, you can jump to the first test article previously released by the PConline evaluation room "ROG Gun God 6 game this first quick review: RTX 3070Ti laptop GPU brings 38.5% improvement Play 2K games! 》
At the same time, in order to show the performance improvement of the Core i9-12900H, we used the flagship processor of the previous generation for data comparison, namely the Core i9-11980HK of the Tiger Lake-H family (the test platform is MSI attacking GE76, and the single baking stabilization is about 70W after replacing the 7921 silicone grease) and the AMD Ryzen™ 9 5900HX (the test platform is ROG Gun God 5, liquid gold heat dissipation, and the single baking power consumption can be stabilized at about 80W. Basically can run full Turbo).
Theoretical performance test comparison
CPU-Z is a commonly used processor test software, which has been updated to version 1.99 and can be well adapted to the hybrid architecture design of the 12th generation Core processor.
Running the Version 17 test, the Core i9-12900H single-thread score was 798.2 and multithreading score was 8627.7. Compared with the Core i9-11980HK, single-threaded is about 20% higher, and multi-threaded is nearly 40%.
Geekbench 5 is a popular cross-platform processor performance test software, the Core i9-12900H has a single-thread score of 1962 and a multi-thread score of 14542.
From the test results, compared with the Core i9-11980HK is also a significant improvement, and significantly ahead of the Ryzen™ 9 5900HX.
The Cinebench series is the more common benchmark software developed on Cinema 4D to test processor rendering capabilities and has been updated to the R23 version along with Cinema 4D.
In the R20 version, the Core i9-12900H has a single-thread score of 747pts and a multi-thread score of 7674pts.
The latest R23 version tested the Core i9-12900H with a single-thread score of 1946pts and a multi-thread score of 19718pts.
The Cinebench R20 and R23 tests, compared to the previous generation flagship Core i9-11980HK, the Core i9-12900H's single-threaded and multi-threaded performance improvements are equally significant, and are also significantly ahead of the Ryzen 9 5900HX.
V-Ray is a rendering software developed by CHAOSGROUP, a professional renderer development company, and is one of the most popular rendering engines in the industry. Tested with version 5.0 Benchmark, the Core i9-12900H multi-thread score was 13292vsamples, which was also an increase of nearly 40% compared to the Core i9-11980HK.
3DMark has also launched a separate CPU Profile project to test the performance of different processor threads to better correspond to different types of game loads. In this test, the Core i9-12900H single-thread score was 1068 and the maximum thread score was 8742.
In this test, the Core i9-12900HK is a relatively small improvement over the Core i9-11980HK.
PCMark 10 application performance testing simulates the daily use of PCs by running Office and Edge scripts, and tests the performance of these application scenarios.
The Core i9-12900H has an overall score of 16,542 and is also very good. It is worth noting that this test is very sensitive to the screen refresh rate, the ROG Gunner 6 screen refresh rate equipped with the Core i9-12900H is 240Hz, while the MSI strong attack GE76 screen refresh rate equipped with the Core i9-11980HK is 360Hz, and the comprehensive score of the ROG Gunman 6 also wins in the case of a loss in the screen refresh rate, which further proves the strong performance of the Core i9-12900H.
summary
After the release of the desktop version of the 12th generation Core processor Alder Lake-S, many players were able to delegate new technologies to the notebook platform as soon as possible. After months of waiting, the 12th-generation Core processor, code-named Alder Lake-H, is officially released, and media and players can finally test its performance instead of generic analysis simulations.
From the actual test results, the theoretical performance of Alder Lake-H is indeed very powerful, and it has not lived up to the expectations of the majority of players. Core i9-12900HK as the sub-flagship model of the Alder Lake-H family, compared to the previous generation of Tiger Lake-H's flagship Core i9-11980HK, a single-threaded increase of about 20%, reflecting the Golden Cove P-Core's IPC upgrade, compared to zen 3 architecture of the Ryzen 9 5900HX shows a significant advantage of generation difference; as for multi-threading, thanks to 8 Gracemont E-Core, The improvement is even more significant, with an improvement of about 40% in the rendered scene, refreshing the performance standard of the mobile processor.
It is understood that Intel has also prepared a more powerful mobile processor in the future - The Alder Lake-H55 series, with 8 P-Core + 8 E-Core, while meeting stronger IO expansion, the specifications are completely in line with the desktop version of Alder Lake-S, designed for the top fever game book. The PConline evaluation room will also fully test it, so stay tuned!
