Is my my gpu being limited by cpu

[Thursty2020]

Hello I have an amd ryzen 5 5600g and a rx7600xt graphics card. My gpu always seems to run at 100 percent while my cpu only runs at maybe 40 percent while gaming. I just upgraded to a 1440p 165hz monitor and I'm not getting as high of a frame rate as I'd like. I'm wondering what i should upgrade to get higher fps? Is my cpu a bottleneck for my gpu? Any help would be great thanks!

Bro you are using a 1080p GPU FOR 1440P gaming ofc if will max out at 100%. But yea if you want to game at 1440p I would buy ryzen 7 5700x3d its cheap has 2 more core and that sweet 3D v-cache. Also I would by somthing like rx 7800xt or rx7900gre. I personaly have ryzen 7 570px3d and rx7900gre and I love it. I still have 1080p display but when I upgrade to 1440p i know that I will be able to play it no problem.

The GPU being at 100% is expected and normal, this means nothing is holding it back and its able to run at full capacity. What this is telling you is if you want more performance, upgrade the GPU. 

 

With that GPU at 1440p, this is expected in many titles. In the interim, you can play with FSR where available to gain some performance back. FSR Quality will effectively be 1080p rendering for the GPU so performance will increase.

No. If the GPU was limited by the CPU it would be well below 100% usage.

 

It running at 100% is what you want, that means you are getting its full performance.

 

Frame rate being lower than expected in this case means you need a faster GPU.

Thanks for the answer's everyone i guess I didn't even realize the card couldn't do 1440p. I was thinking of upgrading to either a 4070 or an rx7800xt. Will the cpu be a bottleneck if I upgrade the gpu? Also if I needed to upgrade my cpu to something more powerful would my asus prime b450 motherboard be ok with a more powerful cpu in it ?

Short answer, No. 

7800 is not that powerful to bottleneck this CPU at 2k.

Yes, at some point depending on the game. 5600g is not a great chip, ultimately. Throw a 5700x3D in that system and you likely won’t have to worry about it for a long time. 
 

And the card you can and clearly does play games at 1440p, hell I do it with an RX6600. FSR is your friend. 

[Thursty2020]

I will try the fsr and see if that helps. It's not like my game is unplayable just was hoping for a little more fps. Sounds like I can just upgrade the gpu when I decide to upgrade and that should help alot. Thanks for the help

Keep in mind that the CPU's performance doesn't change based on resolution. A 5700X3D will not give you more performance at 1440p than at 1080p if you are CPU-limited at both resolutions. It'll just perform the same.

 

As resolution goes up, the GPU's workload gets harder so you become more likely to be GPU-limited.

That makes sense I'll keep that in mind

I think CPU-limited is a typo?

No, it isn't.

 

What I'm saying is this - if the 5700X3D is capable of 150 fps in a given scene in a given game, and your GPU is capable of more than 150 fps at both 1440p and 1080p, then you will be CPU-limited at both resolutions and just get 150 fps.

 

The poster I replied to seemed to be implying that you need a better CPU for higher resolution when they said "But yea if you want to game at 1440p I would buy ryzen 7 5700x3d." I was trying to make sure it was clear to OP that this is not the case. Even in a completely CPU-limited situation, you will not see a bigger gap between, for example, the 5600G and 5700X3D at 1440p than you do at 1080p. If you are completely CPU-limited on both CPUs at both resolutions, then the gap between them will be the same at both 1080p and 1440p.

But that means you are GPU limited? 

The deciding factor is how fast the GPU runs, as the cpu can go faster as is, and getting an even faster one would be a waste as the GPU is setting the limit?

What part of my post are you responding to here?

 

In my discussion I was specifically talking about "if you are CPU-limited." You can be CPU-limited at any resolution.

I was responding to the following phrase:

"Keep in mind that the CPU's performance doesn't change based on resolution. A 5700X3D will not give you more performance at 1440p than at 1080p if you are CPU-limited at both resolutions. It'll just perform the same."

 

I agree that the performance of the CPU will not change depending the resolution. But if OP is CPU limited, a 5700x3d WILL give a better performance. On both resolutions.

The takeaway is, that OPs system will not become faster by getting a faster CPU if they are GPU limited.

So I assumed that you meant: "A 5700x3d will not give you more performance at 1440p than at 1080p if you are GPU-limited at both resolutions."

Yeah, that's also true! And you're right that upgrading to the 5700X3D will improve performance if OP is CPU-limited.

 

Like I said before, my main point was that the post I responded to seemed to imply that you needed a faster CPU for higher resolutions, and I'm trying to make sure OP understands that's not the case.

I think we completely agree

I really just wanted to know at 1440p is my GPU being limited by my CPU and from what I gathered thats not the case. Sounds like I need to upgrade my GPU if I want more fps at 1440p.

This is something you can figure out for yourself by following the techniques laid out in this video:

 

As a general rule, if your GPU is at or near 99-100% utilization most of the time, then you are mostly GPU-limited and would benefit from a GPU upgrade. If it's below that, and especially if it's consistently below 90% utilization (and presuming you don't have a frame cap or V-sync in place), then it's probably being limited by the CPU (regardless of the CPU usage).

 

Another test you can try is to drastically reduce the resolution. So if you're running at 1440p, try dropping the resolution to 720p (1/4 of the pixel count). If the performance goes up significantly, that indicates that you were GPU-limited at the higher resolution. If it stays about the same or only goes up marginally, that indicates that you are more CPU-limited.

With a 7600xt my money is definitely on the GPU being the limiting factor. Especially with your initial post. That it was 100 %gpu load at 1080p and maybe 40% cpu load. 

Going til a bigger monitor is making your GPU working harder. So yeah... if you are unhappy with the current fps (turn off the fps counter to see if you actually notice low framerate, and it's not just knowing that it's lower than what you want), then start saving for a bigger gpu

Best move now is to get a 7900GRE, or if you cannot afford it, get a 7800XT.

 

Anything less will probably not give you the kick you are looking for.

 

Why not the Nvidia equivalent? Because they cost more and the driver takes up more CPU resources. This will expose you to greater risk of CPU bottleneck.

 

If upgrading the CPU, go for the 5700X3D. Ensure the BIOS of your B450 motherboard is up to date and there wont be any issue
