In 2021, Intel released the 12th generation of Core Alder Lake processor, a new hybrid architecture design of "performance core+energy efficiency core", which achieved a balance in performance and cost, leading Intel out of the "shadow" of AMD Zen 3 processor and the 11th generation of desktop Core.
Although the 12th generation Core was highly competitive, it only included six desktop CPUs at that time, and did not cover the medium end desktop and notebook platforms. On January 5, everyone finally got together on CES with the mobile version and the desktop version of the 12th generation Core. The mobile version includes 28 new products, and there are as many as 22 new products on the desktop, covering almost all product lines and price segments from the dual core Celeron to the top i9.
And AMD also released a new Sharp Dragon 6000 series mobile processor on CES, and the new processor war on the X86 platform has begun. Will this year's show be "Intel Counterattack" or "AMD Defending the Champions"?

Including the previous 6 models, the current 12 generation Core desktop product line has 28 products. The i9, i7 and the top two i5 have energy efficiency cores. The number and configuration of cores of the next product have not changed much:
There are five i9s on the top, all of which are 8 performance cores+8 energy efficiency cores, with 30MB L3 cache. TDP ranges from 35W i9-12900T to 125W i9-12900K/KF, with the highest frequency of 5.2GHz
There are also five i7 series, all of which are 8 performance cores+4 energy efficiency cores, with 25MB L3 cache. TDP ranges from 35W i7-12700T to 125W i7-12700K/KF, with the highest frequency of 5.0GHz
There are nine i5 series models, all of which have six performance cores. The most advanced i5-12600K/KF (2.8-4.9GHz) also has four energy efficiency cores, 20MB L3 cache, and 125W TDP. Others include i5-12400/i5-12400T/i5-12400F, i5-12500/i5-12500T/i5-12500F and i5-12600
There are five i3 series, all of which are four performance cores, including i3-12100/i3-12100F/i3-12100T i3-12300/i3-12300T
Pentium has two models of G7400 and G7400T, and Celeron has two models of G6900/G6900T, both of which have only two performance cores.
Note: The K suffix is the overclocking version, the F suffix is the non core display version, the KF suffix is the non core display overclocking version, and the T suffix is 35W TDP (although the i9-12900T is 35W TDP, the Turbo power is still up to 106W).
Of course, what makes players most happy is that the H670, B660 and H610 motherboards released together can effectively lower the price of the U-suite of the 12th generation Core board compared with the expensive Z690 motherboard.
In addition, Intel finally updated the official radiator, including the RH1 radiator with RGB light, copper bottom, and i9 that can press the Turbo power of 202W; The i3 to i7 products are equipped with RM1 radiators, which can cope with 180W Turbo power CPUs, while the entry-level Pentium and Celeron are equipped with RS1 radiators.
Mobile terminal: 3 series, 28 new products, claiming higher performance per watt than M1 Max
The mobile terminal is also very busy, including Alder Lake-H standard press version for high-end game books, Alder Lake-U low-voltage version for ultra-thin books, and Alder Lake-P series for workstations, a total of 28 products.
The leading ones are the eight Alder Lake-H standard platen processors from i5 to i9, all of which are 45W TDP, the ones with suffix 50 are all versions of four energy efficiency cores, and the rest are all eight energy efficiency cores:
The i9-12900HK, i9-12900H, i7-12700H, and i7-12800H are all 6 performance cores+8 energy efficiency cores (20 threads in total). The highest frequency of the first two performance cores is 5.0GHz, and the last two are 4.8 and 4.7GHz respectively;
The i7-12650H has 6 performance cores+4 energy efficiency cores (16 threads in total), with a maximum frequency of 4.7GHz;
The i5-12600H and i5-12500H are 4 performance cores+8 energy efficiency cores (also 16 threads). The maximum frequency of the performance cores is 4.5GHz
I5-12450H is 4 performance cores+4 energy efficiency cores (12 threads), with the highest frequency of 4.4GHz
Intel said that more than 100 products will use 12 generations of standard pressure processors, covering different products from 35W to 65W. It claims that the performance per watt is higher than that of Apple M1 Max and AMD R9-5900H (here is the energy consumption ratio stretched due to the absolute performance improvement. Apple: Can it still compare with my 35W CPU?), 1080p game performance is improved by 28%, and content creation performance is improved by 44%.
The new Alder Lake-P series processors are specially designed for the workstation platform. There are 6 types in total. The core specifications are consistent with the Alder Lake-H standard pressure plate, but the frequency is reduced in order to pursue energy efficiency, and the TDP is reduced from 55W to 28W.
There are 14 models of Alder Lake-U low-voltage version for ultra-thin books, 7 models of 15W TDP (named "12X5") and 7 models of 9W TDP (named "12X0"), mainly due to frequency differences. Here we mainly mention the former:
2P+8E A total of 12 threads of i7-1265U and i7-1255U (both with 96EU GPU), i5-1254U and i5-1235U (only 80EU GPU, lower frequency)
2P+4E 8-thread i3-1215U, 64EU CPU
Pentium 8505 and Celeron 7305 are both 1P+4E with 6 threads
AMD Reelung 6000 series processor mobile version: high-frequency CPU+doubled core display performance
Also at CES, AMD also released a new Reelung 6000 series mobile processor, including TSMC's 6nm process, the new "Zen 3+" architecture CPU, and RDNA 2 architecture core display. The new processors include two U-series low voltage versions (15W to 28W) and eight H-series standard pressure versions (35W+and 45W+).

The Zen 3+architecture is mainly to improve frequency and power management: the maximum frequency of R9-6980HX and R9-6980HS is 5GHz, and AMD claims that the multithreading performance of R7-6800U is improved by 130% (but AMD's 6800U is 28W, not 15W); Reduce idle and high-frequency power consumption, and improve the endurance of mobile devices. AMD claims that the power consumption of web browsing and video playing will be reduced by 15% - 40%.
Other CPU improvements include support for DDR5 memory (DDR5-5200 and LPDDR5-6400), support for PCIe 4.0, USB4 native support (can run Thunderbolt 3), and AV1 hard solution.
Compared with the CPU part, the GPU part is much more exciting. RDNA 2 is the strongest core display in the history of AMD, and its performance is directly doubled. The RDNA 2 core displays 12 groups of CUs, and the frequency is also increased from the previous generation's 2.0GHz to 2.4GHz. The cache is doubled, the raster performance is doubled, the rendering backend is doubled, and ray tracing is supported, Awesome！
Compared with the R7-5800U (15W) of the previous generation, AMD claims that the game performance of the R7-6800U (28W) has increased by 1.8 times to 2 times, 1.2 times to 3 times the performance of competitors in 1080p games. With AMD FidelityFX technology, it is claimed that the number of game frames can be increased by 20% - 60%. In addition, the 35W standard pressure platform and AMD graphics card can use SmartShift Max, allowing the CPU and the unique display to dynamically adjust power to improve performance.
AMD said that the new products equipped with the mobile version of the Sharp Dragon 6000 series processor will be launched in February, and more than 200 related products will be launched in 2022.
2022 Notebook Mobile Processor War Opens
After years of toothpaste extrusion development, the X86 platform processor has made great progress in recent years, both on the desktop and on the mobile side of the notebook. Especially for CPU, the progress speed of X86 platform is far faster than that of ARM platform. When Qualcomm, Samsung and MediaTek all hit a bottleneck due to the public CPU architecture of ARM, the X86 platform last year had 5000 Reeves, and this year there were 12 generations of Core and 6000 Reeves. Intel and AMD had a good fight.
For Intel, The hybrid architecture introduced by the 12th generation Core is more like Apple's "performance core+energy efficiency core" (P core and E core), rather than the "big and small cores" of Android/public ARM. The multi-core performance is improved by stacking cores with smaller energy efficiency cores, while the single core performance is pushed by large-scale performance cores, which can continue to extend and straighten the energy consumption ratio curve of the processor.
If there is any obvious disadvantage of the 12th generation mobile version, it is the design of "performance core+energy efficiency core" and a large number of SKUs, which makes it exponentially more difficult to understand product specifications. Even players can easily see the hoops.
AMD side, Supported by TSMC's strong process advantages and Zen architecture, the Zen 3+architecture can continue to drive up the frequency. From the performance of the previous 12 generation Core on the desktop, the CPU performance of the mobile version of the 12 generation Core may be higher than that of the Reelung 6000 series mobile version. However, the biggest feature of this generation of 6000 Series Reelung Mobile Edition is the RDNA 2 GPU with doubled performance, which can greatly reduce the threshold for 3A masterpiece entry.
It is not known whether 2022 will be the "Intel counterattack" or the "AMD defending battle", but the battle of notebook mobile processors has begun. Before the large-scale distribution of the 12 generations of Core and Reelung 6000 series notebook products, it is no longer recommended to buy the products of the previous generation, so as to avoid the tragic story of "entering the national army in 49 years".
