- L3 caching issue fixed on Windows 11 Beta and Release Preview.
-
From what i read it only fixed the latency not the bandwith
ID: hgrzsxdID: hgs43rmIf you double click you get worse and worse result then sometimes it shows good result sometimes go's as far down as 100 even

This did lower my L3 latency back down when tested with AIDA64, but the various bandwidths are still down by ~10% when compared to older OS's. This with on my TR 2950X in both UMA and NUMA modes.
ID: hgs5u8uYeah I feel the bandwidth issue isn't yet solved
Maybe report on Feedback Hub in case they are unaware?

NEWSL3 caching issue fixed on Windows 11 Beta and Release Preview.
No, it's still not fixed.
ID: hgrxypmAre you on the latest Beta/RP?
It was released today
This will prolly make it to stable next week
Someone else shared their screenshots. Noticeable improvements compared to Win11 numbers
ID: hgry999Are you on the latest Beta/RP?
Yes I am, the newest insider preview from today and be sure that L3 bandwidth is not fixed, at least not on 2 chiplet cpus.

This is flared as News not Rumour because the source is MS themselves
Hope that's fine?

It does not fix the latency problem on Ryzen 2000 specifically 2700x. (I have)
ID: hgtcy8sthat's because L3 fix from microsoft is only for cppc boost which 2000 series don't have
if i switch to p-state boost on my 3900x, the latency bug is still there 40ns for L3
ID: hgu5m0bJust saying prior to this issue in win 11 my 2700x acted Normal with speeds and tge l3 cache latency was 10 ns now its between 27 and 31 and slow.
The latency issue is separate from the cupcakes issue. That fix is scheduled to roll out on the Tuesday after next tuesday.
