How can I know if my CPU is ok? (30-35% usages)

The most game i get buttleneck with my GPU 7900XTX my cpu go around 30-35% and get 100% or event close
How it possible he get block with so low usage it mean something wrong?
it happened in most games have some game for example get I bottlneck with 60-70% CPU usage but most game I get only 30-35%


My score on multicore in cinebench is 15,300 so it look fine but in game i get blocked.
If you need any picture I can add.
What do you think?

addition info:
I play games from 2020-2021.
ultra setting without RT or FSR.
play on 2K.

You will never get 100% CPU usage if the application you're trying to run isn't fully multithreaded and capable of maxing your processor's thread count completely. You never filled your CPU specs but 35% is likely fine if you're running a i7 or i9, perhaps a similar Ryzen.

And you're also running a Radeon, in most games you're stuck with their poorly threaded DX11 driver that operates in an immediate context, resulting in lower CPU utilization features as the driver is not capable of deferring contexts onto extra auxiliary CPUs like the Nvidia driver can.

I've never had 100% usage in games with my 5800X as I play with 6700 XT at 4K so the GPU is the bottleneck on my case.

You didn't mention your CPU but my guess would be that it simply has enough horsepower that it won't go to 100%.

I use only 7600X it got 6 cores only.

and yea I know ill never get 100% usage but 30-35% it very low it feel less then 4 cores

7600X has a high IPC so it's in most cases faster in games than my 5800X. I got this just because I didn't want to move away from AM4 yet.

I just have a feeling that the game simply doesn't need all that CPU power of that 7600X.

It’s fine. The vast majority of games will heavily use a single core, two at best. Other cores will still be used, but for relatively light loads. Especially if you run frame limiters or VSync. At 60Hz you will barely use a modern CPU, unless you play something that has intensive calculations like Paradox Grand Strategies or Civilization on huge maps in late-game.

 

[P4-630]

If you see 95~100% GPU load while gaming you're fine, then at least your CPU isn't the bottleneck.

You can in picture for example.

The GPU does not 100%.
no one from CPU core on 100% and I get buttleneck so it ok?

it happened in most games

 

[P4-630]

Well unfortunately with 85% GPU load uncapped fps, you do have a CPU bottleneck...

no one from CPU core on 100% and I get buttleneck so it ok?

100% CPU load isn't needed to become a bottleneck....

Yea I know but it mean my CPU is fine? because he use very low usage.
I add another picture

If you want to fully utilize your GPU you'll need a better CPU or change the ingame settings.

Game setting is ultra on 2K.

and about improve CPU in future ill upgrad to 8800X3D but curentlly ill stay with him.

The question is if my current CPU it ok, because so low usage it weird for me.

 

[P4-630]

Here you see my CPU (i7 12700K all 8 P-cores @5Ghz) / GPU (2070 Super) load in GTA V 1440p.

My CPU load is just at 28% which varies upto about 35% load but my GPU load stays in the 95~100%.

Disable Hardware Acceleration in the browser - and run couple of 8K Videos in the background while playing games (depending on game - 1 video could be enough for demanding titles, while others might need couple of extra 8K videos to keep your CPU close to 100%). Cinebench could do a better job at stressing the CPU - but not sure if you could play any modern games while it's running (never tried it tho, so really - couldn't say).

 

[Ruru]

I'd say that RX 7900 XTX is overkill for 1440p (I hate the marketing term "2K" ), that card deserves a 4K or a 1440p ultrawide monitor.

How can I know if my CPU is ok?

Typically, a CPU either works, or it doesn't. So if your CPU was not okay, most likely your computer would fail to boot.

Now for sure, lots of things can adversely affect performance of the CPU. These include heat, insufficient RAM, insufficient free disk space, malware, bottleneck with graphics, failing drive, and more.

That I see nothing wrong with your system. However, it would help us help you better if you filled out your TPU System Specs.

Mostly. Though I've had two cases when I've had a defective CPU core.

But that's not the OP's case here yet just saying that something like that can happen as well though it's hella rare in normal situations.

It's much better to have an overkill GPU than gaming at 1 FPS. At least you don't need to upgrade any time soon.

OP: on top of what @Dr. Dro said I'd also add the fact some games are optimised so poorly they can't properly use ANY hardware whatsoever and you get low usage, stuttering, frame losses and other annoying stuff regardless of what your PC configuration is and what your OS configuration is.

If your games run smoothly, don't crash, don't feel like you get hammered upon your head every once in a while and nothing stupid is happening then stop worrying. 30% CPU load doesn't mean it's bottlenecking anything.

Somewhat a good point, at least the upcoming titles will still run well if the OP doesn't upgrade his/her monitor.

And in case they do, FSR/XeSS will restrict that from spoiling the party.

I see 44% overall CPU load in the last screenshot and CPU8 60% load.... With it's GPU only at 85% load, either a CPU bottleneck assuming the fps are uncapped, or the game just runs horribly...

 

[Macro Device]

or the game just runs horribly...

This is more likely to be the case, unless OP's CPU is massively overheating. 7600X is enough to 100% utilise an RX 7900 XTX at 1440p Ultra in basically any game.

 

[P4-630]

59 degrees C according to his screenshot.

Whoops, sleep deprivation makes me blind.

Game is made badly it is then.

Yea but the most games usage is 30-35%

it happened for most games
