For anyone with an AMD central processor thinking about upgrade to Windows 11 , you may want to deem off just a bite longer until AMD can piece a dyad of bugs that can cause performance drops of as much as 15 % .
In arecent notice release by AMD , the party called out two different outlet that are affecting the performance of its C.P.U. in Windows 11 . The first glitch affects a CPU ’s L3 cache and can cause latency to increase by as much as 3x , which can have a major impingement on performance especially in apps or games that rely heavily on cache and memory speed .
AMD claims the oecumenical carrying out rack up from this microbe is around 3 to 5 % , though , in some fast - paced esports game , AMD says performance can be reduced by as much as 10 to 15 % .

As for the other bug plaguing AMD C.P.U. in Windows 11 , AMD did n’t allow for any specific figure regarding its performance impact but it say there ’s presently an issue with the UEFI CPPC2 scheduler that may cause the CPU to not always select the fastest magnetic core in sure situations . Notably , AMD does say that CPUs with more than eight nub and a TDP above 65 Isaac Watts could meet even dandy belittled functioning , while less powerful CPUs take a smaller hit .
These two bugs currently affectevery AMD CPU compatible with Windows 11 , which includes Ryzen 2000 , Ryzen 3000 , Ryzen 4000 , and even the most recent Ryzen 5000 chips , along with a handful of enterprise EPYC chips .
AMD tell it ’s working with Microsoft to fix the outcome , with AMD forebode that patches to address both hemipterous insect will be advertize out to exploiter sometime later this month . Specifically , the mend for the L3 stash issue is expected to get in as part of a Windows update , while the patch for the UEFI CPP2 issue will arrive as a freestanding computer software update .
So whileI’ve generally delight my clock time with Windows 11 so far(aside from annoyances about needing to signalise in with your Microsoft story and changes to the Taskbar / Start Menu ) , it ’s usually best to wait a few week or even a month or two before upgrading , so OEMs and app makers have metre to retrieve and fix any bug they might not have arrest prior to release .
[ Update : 10/21 ] Today , AMD issuedan updateregarding the two major operation bugs for AMD CPUs in Windows 11 . Users suffer from dull public presentation due to L3 cache latency should be capable to put in a plot of ground via Windows Update , while the UEFI CPPC2 issue can be fix via anAMD Chipset Driver update .
