Question Does anyone know why my CPU is underperforming now?

[OrphanSlushies]

I upgraded my 3700X on 5/30/2023 to a Core i7-13700K, when I benchmarked the system on Cinebench 2023, I was getting 30,000 for a score, now in 2024 I am getting about 9000 in score. Does anyone know or understand why I am seeing this, and know how to resolve the low score? I haven't really noticed much difference in the system overall, but if Im losing performance I would like to understand why.

@OrphanSlushies
Are you using Windows 10? Did you do a clean install? Windows 10 does not work correctly with Intel CPUs that have P & E cores. You are forced to use Windows 11.

It looks like the P cores are not being properly used.

 

[thestryker]

Was that HWMonitor open during the whole run? If so then Cinebench wasn't using the P-cores at all. Have you done anything with processor affinity, like using process lasso etc?

While Windows 11 has better integration with Thread Director and works better this would not be related to Windows 10 vs 11.

Hey!

Cinebench 23 for your CPU gets you about 30k but 24 get you 9000. This is because the 2 cinebench versions use different metrics and cant be compared with cinebench 2023 and 2024. Thus also, you cant notice any difference in performance either

9000 for that CPU is an excellent score!

I thought that too at first but check out the screenshots he posted. He had a huge drop in performance while using Cinebench R23 for both tests.

I have heard of this same issue recently where Windows or Thread Director is not properly scheduling tasks on the P cores. Two tasks will end up on one E core even when a P core is available, not doing anything. That seems to be the problem.

arright, since there's not any performance difference, I'd not worry much if I were him. Just the benchmark scores.

When Cinebench R23 scores drop by 21,000 points, it is time to find out why.

@OrphanSlushies

Try moving Cinebench R23 to your main C drive. Make sure it is not in a zipped folder.

Was this a fresh Windows install, or a 'reboot and hope for the best' with new MB/CPU?

 

[ilukey77]

100% cinebench r23 is different than R24 ..
Like another poster said different metrics and such ,,
Install R23 again and you will be back at 30k scores !!

Look at the picture that was posted. He did not run Cinebench 2024. He ran Cinebench R23 and only scored 8886 in R23. That R23 score is way lower than it should be. His 13700K used to reach over 30,000 points in R23. Now it does not. He is trying to find out why.

He ran Cinebench R23 in the year 2024. This problem has nothing to do with Cinebench 2024.

 

[zinkles]

But the fact that he doesn't experience any performance drops concludes that this is an issue with the resources not being used in cinebench specifically, and other programs aren't affected.

So figured out the issue, I had a HWID spoofer that was using dual boot, for some reason after removing the spoofer and dual boot I have my performance back

Some weird dual boot setup I had was halving my power draw for the cpu idk i removed it now all is good

found the issue, weird dual boot set up i had was halving the power draw and only enabling the E cores
