Ryzen 5950X low single core scores in Cinebench R15&R20

As the title states, low single core scores by about 3-5%. the |CPU itself is a beast compared to the 3950X is like another planet

. So far I have tried every possible thing up to a new Win10 installation. I just installed a brand new updated and driver ready Win10 and again same results.

setup:

Phanteks P300 Mesh
Asus 570-P - PRIME X570-P BIOS 2812 - AMD AM4 AGESA V2 PI 1.1.0.0 Patch C (exactly same results except IF 1900 with Patch B)
MSI Gaming Trio X 1080ti
Ryzen 9 5950X
Arctic II 280mm AIO push/pull
Team Group "8Pack Edition" 32GB (4x8GB) DDR4 4133MHz@3800MHz IF 1900

I have tried every possible combination in the bios, so far best is everything auto except the memory and IF which is set at 1900/3800.

Bellow you can see the results from the clean Win10 install, multi core is up a notch, but the dreaded single core is still very low compared to others. Computer runs smooth as a butter, cool fast and still fairly quite. But the idea that sc score is low is driving me crazy already for 3 days straight.

Any input will be greatly appreciated

Are you actually getting 4133MHz?
Thought I read something to do with future BIOS updates to allow speeds above ~3800MHz.
What is the actual speed your RAM is running at?

3800 is posted above 1900IF and 3800 memory. The 4133 is memory model speed

. Will correct.

Download hwinfo and monitor your temps and clock speeds when running cinebench single and multi.

Already have that on the old Win10 installation

The CPU is boosting normally even more then normally

, but single score is still low.

Install previous bios with B patch and test then.

Cant revert bios with the Asus X570P. But have tested on that as well, see bellow.

PRIME X570-P BIOS 2802 - AMD AM4 AGESA V2 PI 1.1.0.0 Patch B

Why not? Can't install the same way as new one?

RavenXXX2 · 7 Nov 2020 at 20:19

Did you test with the older bios? Asus beta bios can be buggy.

bongo78 · 7 Nov 2020 at 20:24

Yes and Yes see above.

RavenXXX2 · 7 Nov 2020 at 20:33

Try disabling Asus Armoury Crate in the bios, if you have installed realtek drivers check in task manager if you have a service called Nahimic service, if so disable it and run test. I have had performance drops with these things.

bongo78 · 7 Nov 2020 at 20:38

Don't have either of those.

RavenXXX2 · 7 Nov 2020 at 20:41

You have Asus Armoury crate in bios, it is under tool. This can slow down boot and shutdown/restart as well as performance drops in some circumstances.

Try with only 1 memory module - single channel - maybe the quad modules overload the CPU too much.
And the memory at DDR4-3800 max.

Single core around 650 is with PBO on otherwise down to silicon lottery. With PBO on are you seeing single cores running over 5ghz? If not you have bad silicon

bongo78 · 7 Nov 2020 at 20:58

See above screenshots, Yes it boosts to over 5GHz with or without PBO. This has nothing to do with the silicon lottery term at all. This is only concerning Cinebench.

heres my 5800x

maybe you do have an issue

Good luck solving your issue.

Exactly as expected

nice. You see why I am bothered now, even your single core score is higher.
