After the appearance of Intel’s 12th-generation Alder Lake processors, many test reports have been released at home and abroad, and the performance has undoubtedly improved a lot, whether compared with the previous generation or AMD. In addition, the concise scientific guide should remind friends who want to start a new processor, that is, the performance difference between the 12th generation processors on Windows 11 and Windows 10. At present, many tests have shown that the Alder Lake processor is in the Windows 10 part. In the test software, the performance has dropped a lot. This is not a hardware problem of the Alder Lake processor, but these test software have not been optimized for the new processor, resulting in the inability to maximize performance. Therefore, it is recommended that those who want to buy it at this stage Best to use Windows 11.
Is it better to install win10 or win11 on the 12th generation cpu? 12th generation cpu install win10 or win11? 12th generation cpu install win10 or win11 analysis (with installation tutorial)
12th generation cpu installed win10 system performance test:
According to the evaluation report of Intel’s 12th generation Alder Lake processor, by running the test software on Windows 11 for i9-12900K and i5-12600K, and then comparing with Windows 10, a huge performance difference was found.
Results for Corona 1.3:
The picture below shows the results of testing Corona 1.3 on Windows 11. Both the i9-12900K and i5-12600K outperformed the 11th generation processors, as well as some AMD processors. The i9-12900L DDR4 completed in 53 seconds and DDR5 in 56 seconds. The i5-12600K DDR4 and DDR5 are both completed in 89 seconds:
However, after switching to Windows 10, the same set of test software, i9-12900K and i5-12600K will take more time (and multiple times), i9-12900K needs at least 185 seconds or more, i5-12600K needs more than 420 seconds :
HandBrake x264 result:
The same is true on the test software HandBrake x264. Compared with Windows 11, the 12th generation processor takes more time on Windows 10:
The test agency pointed out that this is because these software have not been optimized for the 12th generation Alder Lake, so the efficiency core (E Core) is used in the running points, and the performance core (P Core) is hardly used, so the performance of the 12th generation is used. Instead, it was suppressed.
According to the measured screenshots, when running the HandBrake x264 test, the efficiency core is fully loaded, but the performance core is not used much. By analogy, the performance of many games and software on the 12th generation processor + Windows 10 combination will be affected. Of course, not every software is like this, and some can still fully utilize the powerful performance of Alder Lake.
Summary: It can be seen that the performance of the 12th-generation Core under win10 has seriously declined, and it can even be said to be terrible. Both single-core and multi-core will be seriously affected.
This is because the large and small core architecture of Alder Lake relies heavily on scheduling. Win11 has optimizations, but not Win10. Intel’s own thread scheduler seems to be only valid for Win11. Once CPU threads cannot be properly scheduled, it is very likely that a large number of applications are running on On small cores, performance is naturally severely affected. Therefore, players of the 12th generation Core must pay attention, even if you don’t like the Win11 system, you must upgrade to the Win11 system and then use the new generation platform, otherwise the performance will be seriously degraded.
