    Made no difference on my 3700x on an x570 motherboard.

    Drivers won't help CPU performance. Only a cumulative patch or different OS will fix the issue. There is no driver for cache performance.

    Unless the chipsets are the thing that is somehow slowing the l3 cache, there is no way that a chipset driver update would improve performance of the l3 cache.
    If I had to guess, I'd suppose that it has something to do with the way they are handling the cpu scheduler at an OS level.
    The only thing I'd suggest is to keep avoiding Win11 until you are sure they've fixed the issue. There's no reason to use such an inferior OS.
    This is very new hardware and there's no reason why they should be having these problems after 3 years of development.

    Build 22458.1000. I haven't benchmarked the cache previously so cannot say if the previous versions were slower.

    Who cares about 22H1, this should be fixed in 22000.xxx

    I could try it in a VM. They have changed some of the requirements maybe the bug can be reproduced now.

    Although it does not affect me at all, I comment that it is not fixed yet

    If they don't acknowledge the issue they will never fix it.

    They have fixed it on Dev already, just not on Beta.

    Did they ? Or the dev build has different settings for the CPU scheduler and it's fixed ''by accident''.

    One way or another, it's a fix and it will eventually land on a stable build of Windows 11. The question is, will it arrive now or later (2022)?

    If L3 cache was as slow as these benchmarks say it is, your pc would run noticeably slower and games would have much lower frame rates.
    I think this is a bunch of bulls**t caused by benchmarking software reading the numbers wrong due to some software change in Windows 11.
