As a system strongly promoted by Microsoft, Windows 11 has a poor reputation due to various problems. It was previously criticized for not being as good as Windows 10 in performance, but this impression needs to change. The measured performance of Windows 11 25H2 is already ahead of Windows 10, and it is not a margin of error.
The Techspot website compared the performance of Windows 11 25H2 and Windows 10 22H2 today. In order to prevent deviations caused by physical bottlenecks, they used the top gaming platform - Ryzen 7 9800X3D and RTX 5090 graphics card. This configuration should be the ceiling for most people's gaming PCs, although the frequency of 32GB DDR5-6000 memory is not enough.
We compared and tested 14 games, including three levels of performance from 1080 to 4K. I won’t list the results of each game one by one here. The gap in most games is not big, and there are also results where Windows 11 outperforms Windows 10, but after summary, some differences can still be seen.
To sum up, Windows 11 performance is 4% ahead at 1080p.But it is 5% ahead of Windows 10 system in 2K and 4K, this performance cannot be said to be an error. It seems that the optimization of the new system is still possible.
The TS website said that Microsoft mentioned improving CPU/GPU resource allocation and supporting DirectStorage, etc. However, these things cannot be independently verified and tested yet.
Of course, there is another factor to understand why Windows 11 is now leading in performance. Windows 10 is no longer supported, and AMD and NVIDIA have no longer developed optimized drivers for Windows 10.But Windows 11 will continue to be updated, and the impact of driver optimization is also very critical.
Also, they mainly tested N cards and did not test AMD graphics cards, so they are not sure what will happen after switching to AMD's RX 9070 XT.
In addition, the last time they tested the performance of two generations of systems was the performance of Windows 11 23H2 and Windows 10 22H2. That time, Windows 11 lost a little, so they also announced the performance comparison between 23H2 and 24H2. On average, 24H2 led by 9%, but in the highest test, it led by as much as 19%.
If you read the news, you still remember that Microsoft has promised to continue to optimize the performance of Windows 11 in 2026, including background management, performance scheduling, graphics stack and driver optimization, etc. However, it has not yet been determined when these things will be implemented. If it is really done this year, the reputation of Windows 11 should improve significantly.
