Due to issues with the handling of L3 cache and preferred cores, Windows 11 saw some performance regressions on AMD Ryzen processors. This issue is now reportedly resolved by a Windows patch and an update to the AMD chipset driver. If anyone running Windows 11 on Ryzen and observed the regression, let us know if this fixes things for you.

Some context would be nice.

Is this before or after patch? Are the numbers good or bad? :p

After everything, mostly back to normal from what I recall (didn't have a benchmark from Win 10), have to rerun the individual L3 tests in Aida64 after running main whole test (just double-click the window for the test you want to re-run), gets better results so something's up with the entire benchmark bug wise - it's better but it's still a bit slow so L3 speed still not totally fixed (should be around ~900 R\W\C IIRC), latency good though.
 
we know, it came out yesterday and is in ALL the other win11 threads.

did you not at least do a before/after the patch?

yes, why I knew to say latency improves and that the second test run of L3 was much better but still a bit off

L3 latency was 4x higher before fixes on win 11 cache readings all over the place
 
I did not notice any loss of speed but you know - gaming, web, pron, maybe not bothered by the cache issue.

Havent noticed an increase as yet either - got the win patch in last night and the chipset update this morning.

Happy to run tests if someone wants to see how I do.

Come to think of it, new GPU I've run 3d mark before and after and no real change.
 
on the latest build with the newest amd chipset driver and my l3 are still all over the place. ive also reset my ram timings to xmp and it made things worse.

Can you quickly check the following.

1. Have KB5006746 installed
2. Have AMD Chipset driver 3.10.08.506 (or newer) installed
3. Under provisioning packages in AMD.Power.Processor.Settings it shows 7.0.3.5 (or newer)
4. Your power settings are set to AMD Ryzen Balanced Power Plan

Edit:
I see you are still running F35, they have released Bios revision F36e which pairs up with the updates.

1 yes
2 yes
3 not sure where this is
4 there is no ryzen power plan. that went away a long time ago

i am still running f35. there really isnt anything in f36e that has to do with this.

According to MSI, the major changes that the new AMD AGESA 1.2.0.4 BIOS firmware adds is first of all the update to the new firmware which also updates the SMU firmware for AMD's Ryzen CPUs including Vermeer (Ryzen 5000), Cezanne (Ryzen 5000G) and Picasso (Ryzen 3000G). Additionally, it also enables TPM by default on the listed motherboards which means that users will be able to get Windows 11 installed and running on their systems through the fTPM functionality on MSI B550 & B450 motherboards.

Those are the 4 steps posted on the AMD patch notes. So if there is no Ryzen power plan somebody needs to tell AMD.


  • For AMD processors with the "Zen 3" architecture: Systems configured with AMD Chipset Driver 3.10.08.506 (or newer) should report version 7.0.3.5 (or newer) for the AMD.Power.Processor.Settings entry in the Windows 11 Provisioning Packages interface.
  • Systems configured with AMD Chipset Driver 3.10.08.506 (or newer) should have the AMD Ryzen™ Balanced power plan selected and active in the Control Panel > Power Options interface.
You may not need to look for provisioning packages depending on your OS version and setup type.

But most unusual, I’m not touching 11 on my AMD systems and on my gen 11 Intels they have all sorts of power management issues as well. But those effect the PCI interface. Prevents it from waking up from sleep states, very annoying on laptops.
 
If AMD can’t get something as simple as their own checklist correct I am not exactly inspired by their proposed ability to fix the issue.
It is not in the new Windows 11 Power Settings but in the older Control Panel:

This probably makes it compatible to older Windows version for the same drivers.

Ryzen 5000 series CPUs do not require a special Ryzen Power Profile, so it is not installed with Chipset driver package. Please use the Windows Balanced Power Profile for these procesors. Previous generation Ryzen processors will continue to use the Ryzen Balanced Power Profile for optimal performance and this is included in the Chipset driver package.
