A few days ago we learned how the arrival of Windows 11 began to cause the first problems, in this case a poor performance that affected computers that make use of an AMD Ryzen processor. A decline in performance that we now know, can be corrected next week.

And it is that users informed both Microsoft and AMD that after installing Windows 11 their computers offered a lower than usual performance. High latency and memory problems that have caused AMD to put the batteries and work in the corresponding patches that fix the problem.

Two updates to fix the bug

In fact, it was the same company AMD that confirmed the news. Ryzen processors were seeing their performance diminish. There could be cases in which the drop was up to 15%.

The problem had its origin in the latency of the L3 cache, which could triple what could cause 3-5% lower performance in most of the affected applications.

So you can download and install Windows 11 now if you don't want to wait for the notice to arrive at Windows Update

This teams experience problems also with the so-called “preferred kernel” (preferred core), which aims to switch threads to the fastest core of a processor. A performance drop that could be 10-15% for some games.

With these data on the table, AMD has not been slow to react and a statement appears on Reddit in a thread stating that They will release two updates to correct these bugs.

The first will arrive on October 19 and will focus on fixing the bugs that affect the L3 cache. Later another update will arrive, on October 21, focused on solving the problem with the preferred kernels.

This update should appear on computers with Ryzen processors via “Windows Update” within “Updates and security”.

Patch Tuesday exacerbates failures


And the problem has also worsened with the arrival of Patch Tuesday. From TechPowerUp they have measured the latency of the L3 cache of the Ryzen 7 2700X processor after the update on October 12. The figure obtained has reached 31.9 ns which far exceeds the 17 ns of Windows 11 in the original release and let alone 10 ns with Windows 10.

We will have to wait to know if finally next week AMD releases the two patches that correct a situation in which it seems to be the only affected brand, since computers with intel are not finding any kind of problem when it comes to performance.
