What is a Bottleneck in PC Performance?
A bottleneck is like a computer disease. It takes place when there is an imbalance of power between the components of the PC(often CPU & GPU). The faster component can’t keep up with the slower one.
For example a system has a CPU-GPU imbalance. The powerful GPU loads graphics quickly and doesn’t leave enough time for CPU to process them. This limits the GPU’s full potential. This bottleneck can result in longer load times, lower frame rates, and reduces system efficiency.
How Bottlenecks Affect Performance?
A bottleneck in any PC component can affect your system in multiple ways. Sometimes, it may produce low frame rates in games, lag when putting some strain on the system, and create a poor user experience. That’s why, it’s recommended to fix a bottleneck as soon as it’s discovered.
Why Does a Bottleneck Occur?
A bottleneck can occur due to many reasons commonly practiced by users. They include:
- Limited RAM
- Slow storage performance
- Outdated or underpowered CPU
- Entry-level or weak GPU
- Hardware Imbalance
- Very less CPU cores or threads for today’s software demands
- Low processing speed which struggles with heavy tasks
- Small CPU cache that hinders quick data access.
Common Causes of Bottlenecks
What Components Are Most Likely to Cause a Bottleneck?
Want to know which part of your PC is the most likely to cause a bottleneck? They are listed below:
The CPU & GPU are most likely to cause a bottleneck in a system due to one of them being weaker than the other. Other components likely to have a bottleneck include RAM, monitor, and storage devices.
- RAM: It can cause a bottleneck due to slow speed. Use the RAM bottleneck calculator to know if it’s truly the case.
- Monitor: It mostly causes a bottleneck due to weaker display (such as 60Hz, 1080p, etc) and refresh rates with lower response time.
- Storage devices: They experience bottleneck by long loading times and heavy tasks.
What is the Effect Of System’s Components On the Bottleneck?
- RAM: Slower RAM speed than required can impact bottlenecking by slowing down the PC flow, causing stuttering, and low performance when doing tasks.
- Storage Speed: Slow storage speed mainly impacts bottlenecking in loading time. HDD storage causes longer loading times when loading any high-processing apps. SSD storage helps the PC by reducing bottlenecks, while NVMe is the fastest one, but you won’t notice a big difference from HDD while doing regular small tasks.
- Screen Resolution: For tasks with higher resolution (such as 1440p or 4K), the GPU has to work harder for each frame rate, reducing the processing load on the CPU and causing a bottleneck for GPU. Therefore, at tasks with low resolution (such as 1080p), the GPU works quickly and needs the CPU to work hard to meet the GPU’s commands, resulting in bottlenecks for CPU, especially in CPU intensive games.

How To Fix a CPU Bottleneck?
The permanent solution to fix a CPU bottleneck is to upgrade your CPU to a newer version. Quick solutions include:
- Increasing graphics resolution
- Lowering its load by closing background tabs
- Lowering processing tasks
- Overclocking the CPU & RAM
How To Fix a GPU Bottleneck?
- In comparison to fixing the CPU Bottleneck, this one is completely opposite. It is easier and requires fewer solutions. Quick solutions include:
- Reducing graphics resolution
- Overclocking the GPU and RAM to ensure proper cooling reaches the system
- Disabling ray tracing and updating GPU drivers.
How To Fix a RAM Bottleneck?
You can fix RAM bottleneck by increasing RAM capacity such as from 8GB to 16GB, or from 16GB to 32GB, depending on your system, upgrade to faster RAM (such as DDR4 or DDR5), or close memory-hungry apps.
How To Fix a Storage Bottleneck?
Storage bottlenecks can be fixed by switching to SSD or NVMe, and keeping sufficient free space (around 10-15%) to prevent slowdowns.
Are Bottlenecks Reduced by Upgrading a Component?
Yes, upgrading a bottlenecked component strategically can resolve a bottleneck unless it’s improved beyond a limit, such that the fine component becomes bottlenecked due to being a slower model than the newer one.
Is Bottleneck Reduced by Overclocking the System?
Yes, overclocking helps reduce bottlenecks in a system. A CPU bottleneck calculator helps recognize the bottleneck and then overclocking it can reduce the bottleneck by around 5-15%. A GPU bottleneck calculator can identify and help you reduce around 5-10% bottleneck. For safe overclocking, make sure your system is cool.
It is useful, but it may come at its own cost, such as:
- Needing to provide enough cooling
- CPU generating more heat
- Not being compatible with some PCs
- Risking the longevity of the system
- More power consumption

Why is it Important to check Bottlenecks in my PC?
It’s really important to identify bottlenecks in your PC. It helps you to identify the weaker components in your PC and resolve them instead of buying new components that are already working perfectly. It can utlimately save you money, time, and service costs.
Is FPS Related to Bottlenecks? Does it Have Any Effect On Performance?
Yes. FPS is directly related to bottleneck. It’s also affected by bottlenecks. A CPU bottleneck produces higher frame rates, helping the RAM. But, it also causes inconsistent performance with random stutters. On the other hand, a GPU bottleneck produces lower FPS. It’s less than the CPU bottleneck but it’s performance is more stable and consistent.
Why Does My Game Stutter With Space Still Left in the Hardware?
This is not a rare case when games stutter even when the hardware isn’t fully utilized. It could be due to:
- A laggy screen
- Unimportant open background tabs using up your processor’s capacity
- Old or missing drivers, poorly coded games
- Low or misconfigured memory
- Your system slowing down to generate cooling, etc
Should I Upgrade My CPU or GPU First?
If you see any need for improvements from the results of our bottleneck calculator, do it immediately. If you’re experiencing a high load on the CPU with smooth performance of the GPU, it’s a CPU bottleneck and you need to replace your GPU. If you come across a GPU bottleneck with a heavy load on the GPU and smooth performance in the CPU, upgrade your GPU first.
What Are the Best Practices for Upgrading Components to Avoid Bottlenecks?
