Why does a finished PC run better than a self-configured one?

The question may be a bit stupid, but I can't understand that my friend has no problem with a PC with an i5 8400 (6x 2.8) for 1000 euro, and I configure with a PC for 600 euro with an i5 9400F upgraded (6x 2.9) often come to 100% load, and thus have frame drops and a raking mouse in games. We both have 16 GB of RAM and both also a GTX 1050 Ti

Back then I bought my CPU on Amazon for upgrading and the packaging didn't look new. Nevertheless, everything worked, only that my CPU came much faster than the limit and I could not run any other programs such as Discord and Spotify that would consume a maximum of 4% when playing, and he and Netflix, YouTube, Discord and his game without problems at the same time can let go… Can someone tell me why this could be?

The only logical thing that comes to my mind is that it is damaged, or I broke it back then - I accidentally forgot to connect the radiator after installation, which is why it is overheated after a few laps and I immediately took it out to cool down…

I hope it's not…

I would be happy about your answers! If you find a reason, please let me know, otherwise I will buy a new one!

I think that the CPU is really damaged, or that something doesn't match your own configuration, e.g. An inappropriate motherboard or RAM…

I put the PC together on a website where only the right CPUs fit on a maneboar, so where you can see whether the mainboard fits or is configured incorrectly

Then it should really be because of the CPU that it is damaged…

You would have to know the exact hardware configuration of both PCs to say something about the different speed and load.

The different prices alone say little.

My pc

i5 9400F 6 cores 2.9 GHz 9MB cache, 16 GB RAM 2400MHz, GTX 1050 Ti, mainboard from Asus does not know which one

His pc

i5 8400 6 cores 2.8 GHz also believe 9MB cache, 16 GB RAM 2667MHz, GTX 1050 Ti, Msi mainboard does not know exactly which

But even then there are differences with the mainboard, even if the components are compatible, it does not have to be that they are the best or the fastest, there can also be a difference if, for example, a slower chipset or a "bad" cooler is used becomes. The cooler can also play a major role if your CPU is quickly or permanently hot, throttles it so as not to overheat, which means that you will again lose performance.

There can also be differences in the graphics card, the GTX 1050 TI is not the same as the GTX 1050 TI, so each manufacturer has its own specifications, even here, even if it is only a few hundred MHz.

Mine is from 2KFA and mine from MSI

Did you also think of a new thermal paste? Can make a difference

So now was directed to the questioner

Naturally.

There's so much nonsense here…

Close all background applications and run Chinebench R20 (single and multicore, two or three times.
In the meantime you monitor with HWiNFO64 load, clock, voltage and temperature of the CPU.
Write the scores and everything else in here and we'll see.
Which mainboard do you have exactly?

If that were the two here
https://www.kfa2.com/kfa2/graphics-card/10-series/kfa2-geforce-gtx-1050-ti-oc.html

https://de.msi.com/Graphics-card/GeForce-GTX-1050-Ti-GAMING-X-4G/Specification

Then the MSI card seems to be a little better. The MSI card also has two fans, which can also make a difference.

Mainboard I can't say exactly istceins from asus I want a test tomorrow, then I send the result in, if I think about it.

Yo they are, but does that affect the CPU utilization?

You have to know which motherboard you have. Likes it.

The tests take some time, you need patience.
If you want to do a longer (a few hours) load test, Prime95 (AVX off) or AIDA64 are not bad.

Oh, which and how much RAM and especially which CPU cooler you have would also be good to know.

And the packaging didn't look new

sure that there was the CPU that should be in?

Are there any other applications running that are still heavy?

In addition: do you also have the same settings? (e.g. Level of detail in the graphics in the game)

is totally overheated after a few laps

How hot did it get? Up to a good 100 ° C is no problem at all in the short term.
How hot is the CPU getting? If the CPU gets too warm, it will clock down automatically and is then rather full.

Dust / dirt somewhere in the base?

Energy saving mode activated in the system? Or in the BIOS? Is the timing correct?

It also affects which RAM, which board you have installed and whether you have a SSD.

I have 16 GB DDR4 2400mhz but unfortunately only 1x16 and not 2x8 had no experience at that time

Yes is certainly the right one!

No, I was already looking for all possible applications that consume over 1%

Yes, we have the same settings, everything went through with him

I do not remember exactly it suddenly jerked and nothing worked, and I immediately noticed that I forgot the cooler and immediately panicked and took it out to cool down

I'll look for dust tomorrow

No, I haven't overclocked anything and there shouldn't be any energy-saving mode in there, I can't remember having switched it on

Nothing overclocked

I didn't ask about that, but whether the timing was right. So it also runs at 2.9 GHz.

The question may be a bit stupid, but I can't understand that my friend has no problem with a PC with an i5 8400 (6x 2.8) for 1000 euro, and I configure with a PC for 600 euro with an i5 9400F upgraded (6x 2.9) often come to 100% load, and thus have frame drops and a raking mouse in games.

Generally it is a matter of the components used. Some harmonize perfectly and others less so. In general, Intel boxes are bad, no matter which CPU you take from them.

Therefore I can only advise to assemble a box with AMD components.

You don't have such problems anymore and the AMD processors are better than those from Intel. Also from the P / L.

So if the mainboard does not fit, or the socket to the CPU, you will only have fun with your PC if you have fun, understand black screen.

Download CPU-Z, it shows you which mainboard you have!

I can only agree with @ 3125b.
