Installing Windows 11 can slow down applications on your AMD-powered computer, the chipmaker has warned. AMD has published documentation on a few Windows 11 bugs affecting its Ryzen processors, one of which can slow down its processors by up to 15%. This particular bug can triple the L3 cache latency, which in turn can affect applications that require fast memory access.
Most affected applications could slow down three to five percent. If you play “commonly used esports” games, you may feel the impact of the bug much more, as it could slow these games down by about 10-15%. The second bug, like Ars Technica explains, is related to the “preferred kernel” feature which allows a system to use the fastest individual processor cores in a processor.
AMD didn’t mention any specific percentage for the second bug, but the company said its impact was most noticeable in chips with more than eight cores and with thermal design power (TDP) of 65W or more. This includes many high-end desktop chips released in recent years, but suggests that popular series such as the 3600X and 5600X should be little affected, and AMD-powered laptops are unlikely to be particularly disrupted either. .
In its announcement, AMD ensured that it was investigating issues with Microsoft and that they were working on a fix for them. A fix for the first bug will be released as a Windows update, while a fix for the second will be rolled out as a software update this month. For the latter, that might mean having to check AMD’s website for the update and having to install new drivers manually.
