Question CPU or GPU bottleneck

[emilemilov01]

Hello !
Several days ago I asked in the forum what do you think about my prebuild.With your help I decided what components to buy.
But now I have another question.
Do you think i5 13400F will bottlenck RTX 4070?Or do you think that maybe RTX 4070 will bottleneck i5 13400F ?
I will use them for gaming on 1080p (all kinds of games).
The RAM that I plan to buy is Kingston FURY 2x16 GB 3200MHz.
Thank you !

The key thing to do is to remove the word 'bottleneck' from your vocabulary and mindset.

What you want to look for is a balanced part set and good performance.

A CPU bottleneck occurs when the central processing unit (CPU) is operating at capacity and is unable to keep up with the demands of the graphics card (GPU). This can cause a variety of problems, including low frame rates, stuttering, and crashes. A GPU bottleneck occurs when the GPU is operating at capacity and is unable to keep up with the demands of the CPU.

You have a good setup. Forget the word bottleneck. In some games with some game settings you will be cpu limited, in others you will be gpu limited. Enjoy the system and don’t worry about something that is not a problem.

There is no such thing as "bottlenecking"
If, by that, you mean that upgrading a cpu or graphics card can
somehow lower your performance or FPS.
A better term might be limiting factor.
That is where adding more cpu or gpu becomes increasingly
less effective.

You ask a legitimate question, namely is a 13400 processor a decent match for a RTX4070 graphics card?
Not knowing what kinds of games you play and at what resolution, I would say that is a good combination.

Hey there,

As the other posters have said, the term 'bottlenecking' is often misunderstood.

Your choices are very well suited. A good balance. The CPU sends pre rendered frames to the GPU. The GPU takes that data and renders the details on screen. Sometimes the CPU is waiting on the GPU, and other times the GPU is waiting on the CPU. That effect is limited by your choices. Enjoy the nice FPS. What res are you gaming?

My resolution is 1920x1080 75 Hz.
I play all kinds of games,without competitive shooters like Valorant,Apex Legends,PUBG.

Well your proposed cpu and graphics card combination far exceeds the capacity of your display. If there's any sense of bottleneck to be had, it's the monitor. At least you won't have to upgrade system for a very long time.

 

[hotaru.hino]

Unless you're running V-Sync, the display is not a factor. The GPU is going to work as fast as the CPU can feed it, regardless of what the monitor is doing.

In addition, there's a feature called DSR on NVIDIA and VSR on AMD.

It's not a forceful restriction no but a practical one. We both know that.

That's your bottleneck.

 

[emilemilov01]

That's your bottleneck.

I know but I don't have enough space for bigger monitor.

What is your current monitor?
You can get monitors running high resolution and high refresh rates in almost any size.

Can you give me some examples for 21.5 monitors with higher resolution than 1920 x 1080 and higher refresh rate than 75Hz.

 

[geofelt]

Looking at newegg and filtering, I do not see any 21.5" monitors that have higher than 1080P resolution let alone 75hz.
Is your size requirement based on some sort of desktop space restriction?
Perhaps a 27" monitor mounted vertically would be the same width as a 21.5" monitor.
