Intel Core i5-6400 performing below expectations (with UserBenchmark)

knut.leiss · Dec 5, 2018

I am not into tweaking me PC. Just use it for WWW, Office and some games with low demands. Anyway, I just checked the performance of my hardware with userbenchmark.com and it gave me this result:

https://www.userbenchmark.com/UserRun/12651472

Everything seems fine but the CPU performance. 5th percentile is really bad, and I don't see any good reason for this. What also sounds strange to me is, that turbo (2.15GHz) is lower than base clock (2.7GHz).

My questions:

■What could be the reason for this bad performance?
■Which tests could I do to understand the problem better?

Thanks for your help in advance. Let me know, if you need any further information.

PS: All drivers are up to date.

how is your cooling solution?
have you checked your temps to see if you are thermal throttling?
have you gone into Windows power settings and enabled high performance mode?

1| You're using Userbench, that is the reason it seems bad to you. I don't use that site nor do I suggest people use it for want of a better term.
2| Could you state what sort of tasks you tax the system with? List the titles for the games you play. Please don't add etc to this sentence.
3| List your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

QwerkyPengwen :

Cooling solution: Intel CPU cooler and standard case cooler. But I am quite sure, this is not the problem.RealTemp 3.70 gives me very low temperatures (e.g. 35°C) when I run the benchmark.

Power settings: This is not a laptop but a "regular PC". As far as I can see, there is no energy saving plans enabled.

Nonsense. They are there in settings regardless.
Go to search and type in Control Panel.
Once CP is open, click the blue text in the top right and switch from category to either small or large icons (whatever your preference) then go to power options.

If it's not in high performance mode and you don't see high performance mode, there is an option underneath the two performance mode options with a drop down arrow that says click to show more options. It will be hiding in there.

Lutfij :

ad 1) So, you are saying, there might be no problem after all!? Well, so far, I have no issues with my PC when working with it. Only Thunderbird is terribly slow, when I access an IMAP folder with very many messages. But I guess, this is a problem of Thunderbird/IMAP. I just posted here, because of the benchmark result which did confuse me. Finally, I don't want to use my CPU way under its potential... Is there an other benchmark method for the CPU, which you could adviose me to use?

ad 2) I cannot list all programs I ever used, but the most used ones are: Google Chorme, Mozilla Thunderbird, MS Word & Excel, Starmoney (Banking software, sometimes quite slow as well), Java-Editor (educational Java editor), dropbox, 7zip, Acrobat Reader, CDex (CD ripping), GoldWave (audio editor), IrfanView, VLC Player, The Witcher 1, Minecraft, Deponia, Civilization V

ad 3)

Use Cinebench to get test results of your CPU.
Also, before hand, please double check what I said about high performance mode setting in Windows power settings.
https://www.maxon.net/en/products/cinebench/

Can also run GeekBench
https://www.geekbench.com/

Here are average test results of the 6400 in Cinebench

And average test results with GeekBench

QwerkyPengwen :

Thanks a lot. It truely were the Windows Power Settings. Quite disturbing...

A new userbenchmark now yielded a 90th percentile for the CPU and even the SSD did raise from 13th to 83rd percentile. Overall, my PC is now at 88th percentile for the given hardware. That sounds good to me...

Also the other two benchmarks provided did yield good results.

Thanks again!
