In a blog post, AMD discussed the benefits of its Ryzen processors with Windows 11: AMD and Microsoft enable new user experiences with Windows 11, powered by AMD Ryzen processors, providing support for the latest features and technologies to improve performance, efficiency, security features, and connectivity. For gamers running Windows 11, AMD Radeon graphics cards are designed to deliver high-performance, highly responsive, and fully immersive gaming experiences. Building on the long history of collaboration between AMD and Microsoft, AMD-powered devices are ready to support Windows 11 experiences from day one.
*We are pleased to continue our close relationship with Microsoft when they introduce Windows 11, with all its features and benefits, which together provide an upscale, streamlined experience for AMD-powered PCs*, said Saeed Moshkani, Senior Vice President and General Manager, Customer Business Unit, AMD. . * Consumers who already own AMD-supported products can experience the innovations of Windows 11 as well as the reliable features and capabilities they are accustomed to from AMD. *
Of course, these advantages mentioned by the manufacturer are not related to all its models because some of them are not supported by Windows 11 (we can mention the first generation but also some of the 2000 series).
This time around, AMD has released information about bugs that can reduce the performance of Ryzen processors running Windows 11 by up to 15%, although the slowdown you see will vary depending on what you’re doing and the processor you’re using. AMD expects both bugs to be fixed later this month.
The first issue that AMD identified is the L3 cache latency up to three times, affecting applications that rely on fast memory performance. AMD says most affected apps will slow down by 3-5%, but some games commonly used in esports could see a 10-15% drop. AMD says that a Windows update will fix this problem later this month, and as long as you check for and install Windows updates regularly, you won’t have to do anything special to fix the problem.
The second error relates to the AMD processor feature trying to use the fastest individual processor cores when performing lightly threaded tasks instead of treating all cores the same way. AMD doesn’t provide a figure for that number, but says the problem may be more detectable in processors with eight or more cores and a TDP of 65W or more. This will include most Ryzen 7 and Ryzen 9 2000, 3000, 4000 and 5000 series desktop processors and APUs. AMD says that a software update, not a Windows update, will be released to resolve the issue later in the year.October. So you may need to install new drivers for your AMD chipset or other software to get the fix.
Issues with AMD Ryzen differ from slower performance caused by some security features based on Windows virtualization. In particular, tests by outlets like Tom’s Hardware have shown that the Memory Integrity Security feature can reduce performance by a few percentage points in some general PC games and tasks, although results vary widely. Depending on the software you’re using and the processor you’re using they use. This feature is included in both Windows 10 and Windows 11, but is disabled by default in both operating systems for all newer laptops and desktops sold by major PC manufacturers.
AMD and Microsoft have already confirmed that they are actively looking into these known issues and fixing them through software updates. Both companies pledge that a Windows Update and a software update will be planned later this month in an effort to resolve these issues: effect on the performance of some of their applications. AMD and Microsoft have identified two issues that the two companies are working closely to resolve to provide the appropriate corrective updates.
In the meantime, some users may want to stay on Windows 10 until AMD and Microsoft resolve these issues.
