Latest builds of 24H2 seems to have a bug causing the CPU score to drop significantly in benchmarks. After digging around, i have finally managed to narrow it down to a feature that has been introduced a while back (drag/drop and pin to taskbar).
Earlier builds were not impacted, i think it started after 26100.1591 but not very sure.
As you can see in the pics (before and after), after disabling the said feature on a fresh clean build of 24h2 (latest release), the score jumped 28%, right back where it should be.
Anyhow, the fix is very simple and straight forward, no tools are required. I appreciate if you could test it out and let me know if it works for you.
Just open CMD as administrator and paste the below, reboot, and you are good to go. Just make sure the feature has been disabled after the restart (try to drag/drop and pin to taskbar, it shouldn't work as shown in the picture).. if it's still working, the score won't increase.
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides\8\2897279119"
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides\8\2897279119" /v EnabledState /t REG_DWORD /d 00000001 /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides\8\2897279119" /v EnabledStateOptions /t REG_DWORD /d 00000000 /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides\8\2897279119" /v Variant /t REG_DWORD /d 00000000 /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides\8\2897279119" /v VariantPayload /t REG_DWORD /d 00000000 /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides\8\2897279119" /v VariantPayloadKind /t REG_DWORD /d 00000000 /f
EDIT
Another way to disable the feature, if this method doesn't work, is to use vivetool:
.\vivetool /disable /id:50556886
