What is a Bottleneck in PC Performance?

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?

  • Hardware Imbalance
  • Limited RAM 
  • Slow storage performance
  • Outdated or underpowered CPU
  • Entry-level or weak GPU
  • 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.

What Components Are Most Likely to Cause a Bottleneck?

  • 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.

Are Bottlenecks Reduced by Upgrading a Component?


Is Bottleneck Reduced by Overclocking the System?

  • 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?


Is FPS Related to Bottlenecks? Does it Have Any Effect On Performance?


Why Does My Game Stutter With Space Still Left in the Hardware?

  • 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?


What Are the Best Practices for Upgrading Components to Avoid Bottlenecks?

Buying such a model that can stay updated and balanced with your system in the future is the key.Keep a proper budget for it, and if you will be buying a new model of your PC’s component in the future, make sure to budget for it smartly.


How Does a Balanced System Benefit PC Performance and Longevity?

Matching CPU & GPU Performance

For a balanced PC, make sure to match the CPU & GPU. They should be compatible with each other to provide smooth and balanced performance. Popular balanced combinations are (Intel Core i5-13600K + NVIDIA RTX 4070, AMD Ryzen 7 7800X3D + NVIDIA RTX 4070 Ti, Intel Core i7-13700K + AMD Radeon RX 7800 XT ).


Choosing the Right Amount of RAM

Choose the right amount of RAM according to your PC’s specifications. High or slower RAM than needed can cause bottlenecks.


Picking Storage for Speed & Capacity

Storage should also be not compromised when building a balanced PC. Pick a storage which is compatible with your PC to maintain speed and capacity.


Selecting a Display That Matches Hardware Power

Select a display that matches the hardware. For an advanced PC, select an advanced display such as a 1440p or 4K monitor with 144Hz+ refresh rate. While, for a normal PC, use a 1080p monitor with 60–75Hz refresh rate.


Example Balanced Gaming Build

Example of a Mid-range Gaming build can be:

  • CPU: AMD Ryzen 5 7600X
  • GPU: NVIDIA RTX 4070
  • RAM: 16 GB DDR5
  • Storage: 1 TB NVMe SSD
  • Display: 1080p 144Hz

Example Balanced Workstation Build

Example of a Mid-range balance workstation build can be:

  • Display: 1080p 144Hz
  • CPU: AMD Ryzen 5 7600X
  • GPU: NVIDIA RTX 4070
  • RAM: 16 GB DDR5
  • Storage: 1 TB NVMe SSD

How Often Should I Check for Bottlenecks in My System?

The main cause of bottlenecks in a PC system is a weaker CPU or GPU, slower RAM, storage, or screen resolution. Check out the real culprit from our bottleneck calculator.

Upgrading your CPU or GPU according to your needs to balance out the system in the end can fix a bottleneck.

Bottleneck calculators analyze thousands of real-world data points on different combinations of components of well-performing PCs and compare that with your component’s performance in games.

The bottleneck calculator is around 90% accurate, depending on the depth of data you give. No tool can be made 100% accurate.

Yes. Our bottleneck calculator  is made to check any PC – build’s bottleneck. You can use it to check the stability of your PC’s components and optimize them for smoother performance.

The bottleneck calculator will tell you your system’s performance. Still, if you want an estimate, around 0% – 25% is in most of the cases, perfectly fine. 25% – 50% is a sign of bottlenecks starting. 50%-75% means your system is not ideal and needs to be updated. And, above than 75% means poor performance, and urgently needs updating.

You can fix a CPU bottleneck by upgrading your CPU version to the latest and most advanced one, increasing its processing speed to ensure everything runs efficiently.

Similar to the CPU bottleneck, you can fix it by upgrading your GPU version to the latest one, increasing its graphic resolution, and generating power to increase efficiency.

Overclocking can help reduce bottlenecks, but it also comes at a price. It reduces your system’s longevity, requires proper cooling due to overheating of the system, and more power consumption, etc.

  • It depends on your needs. Upgrade your GPU first if you’re experiencing a GPU bottleneck while upgrading your CPU first if you’re experiencing a CPU bottleneck works.

Your game can stutter for other reasons, including a bottleneck in any component or software issues like inefficient game code or outdated drivers.

Slower RAM speed than required can cause bottlenecks resulting in slowing down the PC flow, stuttering, and low performance when doing tasks.

Yes, upgrading the component being bottlenecked can resolve the bottleneck in your system.

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 the bottlenecks, while NVMe is the fastest one, but you won’t notice a big difference from HDD while doing regular small tasks.

Absolutely. If your CPU is bottlenecked, it processes data very slowly, and hence the GPU doesn’t work at its full capacity. So, the GPU is limited by the bottlenecked CPU.

Yes. A GPU bottleneck occurs when your graphics card struggles to render frames quickly enough, resulting in low usage of the CPU. This limits the CPU’s potential, even though it could perform better.

Yes. Professional gamers are very concerned about system performance. They regularly monitor for CPU, GPU, or RAM bottlenecks to ensure smooth gameplay and avoid interruptions during competitive matches.
