Intel's 12th Generation Core Mobile surpasses the 2018 AMD Desktop Flagship processor.
At the International Consumer Electronics Show (CES) 2022 on January 5, Intel unveiled a new wave of new products, including new ARC discrete graphics, 12th Generation Core Desktop Edition, and several 12th Generation Core Mobile Editions, divided into high-performance H Series (45W), consumer P Series (28W), and U Series (15/9W) for thin and lighter editions.
Among them, there are a total of 28 mobile CPUs, all of which are designed with large and small cores, and are created by Intel7 process (10nm).
Among them, the flagship chip Core i9-12900HK is the object of attention, it has 6 large 8 small 14 cores 20 threads, 24MB L3 cache and up to 5 GHz frequency, in addition to the integration of 96 units of core display (1.45GHz), the entire CPU Turbo power consumption of up to 115W. As the highest-end, its mission is to fight against AMD.
On paper, the 12th Generation Core, code-named Alder Lake, has a significant upgrade over the 11th generation. Intel says the i9-12900HK is 28 percent faster than the i9-11980HK in terms of gaming, with higher performance per watt than Apple's M1Max and AMD Ryzen95900HX. In some Adobe and Autodesk software, the i9-12900HK performs better than Apple's M1Max and AMD Ryzen95900HX.
So what will the actual performance be?
Yesterday, the Romanian technology review site Lab 501 published one of the world's first reviews of Intel's new mobile Core i9-12900HK (Alder Lake) processor. Packed with Intel's new hybrid core microarchitecture, the CPU successfully beat AMD's desktop Ryzen Threadripper 1950X in the Cinebench R20.
Mobile i9-12900HK run score exposure
The notebook environment used by the tester is shown in the following figure: the CPU is i9-12900HK (K stands for overclockable), including 6 P-cores and 8 E-cores, 20 threads, 24MB L3 cache, and 32G DDR5-4800 (2400MHz) memory.
First, let's look at geekbench 5 running score, single-core 1808, multi-core 14170.
Then in the Cinebench R15 test (CPU), the following figure shows the parameter configuration related to i9-12900HK.
Test results show that the i9-12900HK is an improvement of about 15.4% over the previous generation i9-11980HK and about 18.9% higher than the AMD Ryzen™ 9 5900HX.
Then in the Cinebench R20 test (CPU), the following figure is the relevant parameter configuration for the i9-12900HK.
The test results show that the i9-12900HK score is as high as 6741, which is higher than any previous mobile CPU and comparable to the desktop version of the i5-12600K. It is about 16.8% and 28.9% ahead of the previous generation i9-11980HK and AMD Ryzen™ 9 5900HX, respectively.
Not only that, but the i9-12900HK is also the first mobile CPU to completely beat AMD's Ryzen™ Threadripper 1950X in the Cinebench R20 test, which is a desktop CPU with 16 Zen cores, 180W, and a slightly lower running score of 6670.
Finally, in the Blender 2.78c, WinRar 6.0 and PCMark 8 tests, the i9-12900HK achieved different degrees of improvement.
In multiple benchmark tests, the 12900HK can reach the nominal frequency limit of 5.0GHz, but the temperature has also reached an unacceptable maximum of 100°C and the power consumption is up to 113W.
I don't know how various manufacturers will cope with such heat dissipation pressure on the final mass production computer.
