AMD Ryzen CPUs Are Slower on Windows 11, for Now

By 2 months ago

AMD says it has uncovered a mysterious problem with AMD processors that triggers reduced performance in certain applications running Windows 11. Windows 11 has a problem with some AMD processors, and the team at Red has confirmed that it will have a significant impact on the performance of some games.

AMD has confirmed support for performance fluctuations in certain applications post-Windows 11, and stresses that the problem with AMD processors is due to L3 cache latency, which can be up to three times slower if a small amount of faster memory is cached on the on-board CPU. The good news is that when we were contacted by AMD, we were told that the company is aware that some users may experience performance issues with certain applications when installing the first Windows 11 version on systems running compatible AMD processors.

AMD and Microsoft are working on a software solution to address these problems, which is expected to be released later this month. Memory performance is a critical aspect of modern processors due to their built-in cache and DRAM. These two issues, which affect the performance of their Windows 11-compatible Ryzen processors, give AMD’s CPUs less power in Windows 11 than in Windows 10. AMD and Microsoft have been working on software fixes to address the performance problems in AMD’s Ryzen processors, which will be available later this month. To fix the problems, both companies are releasing updates to Windows 11, a software update that AMD has been releasing for months.

On Windows 11 AMD Ryzen processors have L3 cache latency of up to three times, resulting in a performance drop of 35% for users in many applications, and a performance drop of 10-15% for latency sensitive applications, which can affect AMD’s gaming performance, as memory cache performance is critical to maintaining high gaming performance. Some games may have cache latency issues, and AMD warns that performance may drop by 10 to 15 percent in some games.

The performance problems will be most pronounced on computers with more than 8-core processors with 65W Thermal Design Power (TDP), which includes many of the popular Ryzen processors in Microsoft’s Windows 11. There are other bugs that plague AMD CPUs running Windows 11 and although the company has not provided specific numbers on the impact on performance, it says that there are issues with UEFI and CPPC2 schedulers that cause the CPU to select the fastest core in some situations.

Earlier this year, processor and chipmaker AMD and Microsoft announced in tests of Windows Insiders that some of its processors, such as the EPYC and Ryzen lines, could experience performance losses of up to 15% after installing Windows 11. As a workaround, AMD advised its customers to continue to use supported versions of Windows 10 until Microsoft provides an update to address performance issues affecting the system. Now that Windows 11 has been released to the stable channel, AMD has announced that PCs with AMD processors will experience a performance slump until a patch is released later this month.

AMD has announced that its Windows 11 compatible processors will experience performance losses in applications using the new operating system, with extreme outliers such as sports and gaming titles leading to a 10-15% decrease.

The release is a staggered release so early adopters using AMD-based systems will experience lower performance in some games than Windows 10, but that should be fixed with a software update later this month. As for the Windows update, it’s still a work in progress, but AMD says that coming in October to eliminate the issue will be a relief for people upgrading from Windows 10 to AMD’s Ryzen processors. The 1.5% performance drop on top-end CPUs for Microsoft and AMD will not make Windows 11 users happy.

According to a blog post by AMD, thanks to Tom’s hardware, people who upgrade on Ryzen-powered systems to Windows 11 experience in some situations lower performance. Benchmarks for the new operating system show that AMD’s CPUs used in certain apps perform better than Windows 10 CPUs, but the difference is minimal in other applications.

Microsoft and AMD are investigating two separate issues that affect the performance of AMD CPUs under Windows 11. AMD has released information about a pair of bugs that could reduce Ryzen CPU performance by up to 15 percent under Windows 11, although the degree of slowdown you observe varies depending on what you do and the CPU you use.

AMD and Microsoft have announced that if Windows 11 is running, AMD CPUs will have lower performance for certain applications when Windows 11 is running, according to a blog post by our friends at Tom’s Hardware Spot. Today, AMD reported a problem with its new Windows 11 operating system, where some compatible AMD processors experience performance problems when certain applications run during the installation of the new operating system. AMD announced that some PCs that have its Team Red processors are experiencing problems that could cause a 15 percent performance drop on Windows 11 systems. The company promised that a software update would solve the problem in the coming months.

Microsoft’s recently released Windows 11 operating system reduces the performance of Ryzen CPUs and AMD advised on Wednesday that users can just stick with Windows 10 for now.

AMD has said it expects a Windows update to fix the L3 cache issue and a software update to fix the issue with UEFI, CPPC2 and the preferred core technologies. However, the company mentioned that the performance issues could affect compatible AMD CPUs running Windows 11, including the latest version of Ryzen CPUs. Brand new ones may appear with AMD Ryzen CPUs, but Windows 11 can reduce the efficiency of leisure activities by a lot, perhaps up to 15%, which does not please avid gamers.
