Up to 15 percent: Confirmed performance loss with AMD under Windows 11

Bis zu 15 Prozent: Leistungsverlust bei AMD unter Windows 11 bestätigt

This was already seen in the ComputerBase performance test of Windows 11, and now AMD has confirmed it: Ryzen doesn’t run smoothly under Windows 11 just yet. The fact that the performance loss confirmed by AMD can be up to 15 percent is surprising and raises questions.

AMD Ryzen may lose performance under Windows 11, which was quickly determined by editors with Ryzen Threadripper and Ryzen 5000. AMD confirms that the problems may mainly occur with CPUs with more than eight cores and more than 65 watts. Windows 11 doesn’t really know which core is fastest and sometimes slow. In this case, however, the performance loss is small, as the fastest core is often about 25 or 50 MHz faster than the other in the processor – up to 4.5 or even 5 GHz in single-core scenarios. Effects are manageable.

eSports game is worst case

However, the problem with latency and the storage system is much greater. In the worst case, both can exacerbate the problem by 3 times. To its own knowledge, AMD has found a significant impact here, with 3 percent performance loss in applications in the smallest case, up to 5 percent in other situations. However, the worst-case scenarios are eSports games that have outliers and result in up to 15 percent loss in performance.

AMD and Microsoft under fire

If possible, both problems should be resolved this month via Windows or a software update. AMD’s quick response today is laudable, but it also raises questions. First, the timing: the company wants to bring a fix in October, but why didn’t it take into account restrictions before Windows 11 debuted, whether at AMD or Microsoft, which tested CPUs when expanding system requirements ? So the timing is anything but happy and creates a bad image of both the parties and their cooperation.

So Computerbase’s first conclusion in the Windows 11 benchmarks was already appropriately chosen: If you have Windows 10, you don’t need to switch just yet. Windows 11 is still maturing. Ultimately, it’s no surprise that AMD recommends “Continue using a supported version of Windows 10.”
