Curious different PPD Linux v. Windows 11

Post by pcwolf »

I built a dual-boot machine to run F@H. There is an extreme difference in points per day between Linux and Windows 11.

Same hardware.

AMD Ryzen 5950X on ECO mode through UEFI
32 GB DDR4 memory @ 4000 mHz
NVidia RTX-4070

Manjaro Linux = 12,000,000 PPD
Windows 11 fresh registered installation with all updates = 3,500,000 PPD

I have no background tasks started and running other than standard system tasks.
Is there any explanation for this difference I am not seeing? Is this common in anyone else experience?

I have no help to offer, but if the differences were that excessive I would think that nobody would want to run Win 11 at all for folding. Most feedback I've seen seems to indicate that it works just as well as Win 10.
Fold them if you get them!

Do you have a passkey set on both machines?

Your 4070 alone should be getting more than the 3.5m you get with win11.

I will boot to Win11 then and let it run a few days straight to see if I haven't let the machine "warm up" and reach full PPD.

Same F@H Team and passkeys, same account.

The PPD for individual WUs can be calculated at

https://apps.foldingathome.org/cpu

Search for your username, click a link in the "Last returned" column, then divide the Credit column by the Days column to calculate actual PPD for that task.

Do you leave one CPU core (2 threads) free to feed the GPU on Windows ?

Note : FAH has always been faster on Linux than on Windows due to system and driver architecture differences.
