- Windows 11 25H2 has been put to the performance test
- Based on a series of 40 markers, it will not be faster than 24h2
- In fact, performance is a dead heat, but it is to be expected, because 25h2 is a minor update that does not make big changes
Windows 11 25H2 will not be faster than the 24H2 version in terms of general performance, according to some new tests – although it should not surprise.
Phoronix.com, a site focused on everything related to Linux, has carried out a test (reported by Tom equipment) comparing the performance of Windows 11 25H2 to different Ubuntu flavors, as well as basic Windows 11 24h2.
We must, of course, keep in mind that Windows 11 25H2 has not yet been released, so this comparative comparison uses the prevailing (almost finished) version of the operating system (and I will come back to this point).
The tests – which lasted around forty different benchmarks from various applications, including Luxcorerender and Intel Open Image Denoise – show that Windows 11 25H2 has performance identical to the 24H2 version according to the average of the results.
Ubuntu Linux was about 15% faster than Windows versions in this test battery, in case you are curious.
The comparative analysis was carried out with new installations of these operating systems using stock parameters on a PC with a Ryzen 9 9950X and 32 GB of RAM processor.
Analysis: no increase in performance, but a more reactive operating system may not be far away
Of course, this is an overview of Windows 11 25:2 hours as indicated, so it is not yet completely finished. That said, this is almost done – indeed, the new Windows 11 flavor is now in its final test phase and likely to be published next month. Thus, realistically, there will be no significant difference in the performance levels between the current preview version of the version in the latest stages of the tests and the finite version of Windows 11 25H2.
It is not a surprise, however, because Microsoft has already clearly indicated that Windows 11 25H2 is a minor update. We will get new features, of course, but not many of them – this is not exactly what will make the cut. Under the hood, however, the operating system remains roughly identical – and this is exactly what the dead heat in the performance issues that we see here indicates.
Although it is a game with equality in terms of average of this series of benchmarks, it should be noted that Windows 11 25H2 really loses (up to one or two percentage points) in certain tests and wins by a nose in others to make things on average, of course.
In any case, if you hoped that Windows 11 25H2 could cure part of the hiccups around the reactivity you may have known with 24h2 or improve overall performance, you can forget this idea.
However, Microsoft works at least on strengthening Windows 11 performance levels in a new scheme with operating system testers through which newspapers are kept when a PC undergoes slow performance. Hope is that it will help Microsoft diagnose and solve problems around slow performance in Windows 11 in a more revolutionary way, so the crossed fingers, it works to be the case.
This year’s update being a small one, the probability is that in 2026, we will see more important changes compared to Microsoft – maybe even Windows 12 or whatever the next iteration of the office operating system, but I personally think that we will wait longer for this new generation version).
