Does CPU Affect FPS? (Pros & Cons For Gaming Performance)

Modern computer games use many 3D innovations, which require high-end gaming systems to run HD graphics for optimal gaming performance. Because of this, frames per second (FPS) has become one of the most critical things to consider if you want to have the best gaming experience, especially when playing online games.  

Of course, your computer’s CPU, along with other hardware components such as RAM and GPU, support the game’s performance. But the real question is, does CPU affect FPS? 

In this article, we will discuss what FPS is, why it matters, and understand whether or not your CPU impacts your gaming FPS.  

FPS in gaming refers to the number of images displayed in a single second (frames per second). Like any other medium, displaying images in a game requires individual still frames to create a motion. So basically, your FPS is the number of images displayed in each second. While a second isn’t long, the number of frames shown can make the game look significantly different.  

In terms of gaming performance, FPS plays an integral role. The higher the frames displayed, the quicker the responsiveness to your action in the game. Meanwhile, a low FPS increases your input lag, and if there’s a slight delay, the game can’t display your move until all of the frames of your movement have been rendered.  

In a nutshell, a high FPS rate makes the game feel more responsive, allowing you to have minimal input lag. This can be advantageous, especially in competitive online gaming.

Does CPU Affect FPS? (Compared To GPU) 

Yes, your CPU affects FPS, but it doesn’t have as much impact as your graphics card (GPU). This is because, during gaming, your processor is responsible for taking the data passed on from both the game and player, communicating it to the GPU. It also describes what the game looks like to the GPU to draw it up for you.  

Once the GPU has all this information, it will work on a much heavier process to draw and create the world the CPU described. Therefore, a better GPU has more impact on the gaming performance since translating the information visually requires more power, and a powerful GPU can speed up this process, providing better FPS.  

However, this does not mean that you can have a powerful GPU and an underpowered CPU. If you do this, it will create a bottleneck that will still make a bad performance.

Instead, you can have a decent processor paired with a good quality GPU, providing you with a good balance that will give you high FPS for 1080p gaming. After all, these components rely on each other as the CPU must complete its task first before passing it to the GPU.  

This is why when buying a CPU and GPU, you need to make sure that you create a balance, allowing these components to achieve their maximum potential so that they can give you the best FPS and optimal gaming experience.

Does CPU Temperature Affect FPS?  

Unfortunately, your CPU temperature can impact your FPS. If your processor is running at a very high temperature, it needs to slow down to reduce the heat. This is an automatic process in your CPU to protect it and your motherboard from further damage.

It can also prevent unfortunate events such as your CPU catching fire, causing more harm than it already has. So if your CPU works slower, it affects the information it passes to the GPU, impacting the FPS.  

Keep in mind that an average temperature for gaming is around 65 to 80 degrees Celsius; anything higher than that can slow down your processor. If you are experiencing this, here are some tips that can help:  

  1. 1
    Try to reapply thermal paste on your CPU.  
  2. 2
    If it persists, increase your fan speed or buy a more powerful one. If you are using a stock CPU fan, it is also ideal to upgrade it even if the thermal paste works. 
  3. 3
    Regularly clean your case. When you clean it, make sure that your computer is turned off, and remove all the dust from your fan and the case. This practice will help with the airflow and make cooling easier for the fan.  

However, if you haven’t built your computer yet, it is best to buy a better fan than using a stock fan. This can help prevent overheating issues.

How Does CPU Affect FPS When Gaming? 

Your CPU can impact your FPS when gaming. This means that anything you do on your CPU will directly affect your FPS. Here are some of them: 


Overclocking is one of the best ways to help increase your processor’s power and improve its execution. This means that it can process information faster, sending it immediately to the GPU to translate the data, resulting in a higher FPS.  

As the main components work faster during overclocking, all processes increase speed, resulting in a better gaming experience. However, too much overclocking can be detrimental to your CPU’s overall health. This is because you’re pushing your processor to work beyond its average speed.  


All components in your motherboard are connected to help your computer achieve its optimal performance. This means that each part uses a connector to function and transfer information, which helps achieve the best gaming performance 

These connectors have different capacities. At the same time, the ports also serve other functions and can affect gaming performance. Furthermore, the interface of your motherboard can have a unique and vital role in determining how your CPU and GPU will function, which is why it affects the FPS in different ways. 

Data Process 

Another thing that can have an impact on your FPS is how your CPU processes data. As we’ve established, your processor is responsible for taking the data in the game, feeding this information to your GPU. If your CPU can’t process this information, there will be no data transferred to the GPU, affecting the display output in the game.  


BIOS (Basic Input Output System) is software installed on your motherboard that loads when you boot your computer, right before your operating system. This gives you an interface that allows you to modify the hardware installed in your motherboard. 

Here, you can configure settings such as voltages and frequencies, allowing you to manually overclock your CPU to achieve a higher clock speed increasing your processor’s performance.  

Since you can use this setting to improve the performance of your CPU, this can also boost your FPS when gaming. Just be careful not to overwork your processor, or it may fail quickly.  

Does CPU Affect FPS In Fortnite? 

Fortnite is an online battle royale game consisting of 100 players that fight against each other to be the last one standing. It is a fast-paced, action-packed game that requires players to fight to the death to survive. It’s a first-person shooter game, but you only have one life, so you have to join another game when you die.  

While this game may look like it requires high computer specs, it actually does not, and a pretty old gaming PC can match Fortnite minimum specs. However, you need to tweak some settings to make sure that you stay competitive in the game. For example, having a good CPU can affect your gaming performance.  

While a better CPU can help with your FPS, keep in mind that when you do upgrade it, the processor will work well with your GPU. If it’s too powerful, you might have a bottleneck, leading to a slower gaming experience. So whichever game you play, make sure that your CPU and GPU work hand in hand, or your FPS will suffer.
