What is a bottleneck calculator?

Have you ever felt that your computer is running slow and taking a long time to load programs or games? This type of problem occurs when one part of your computer system such as (a graphics card or processor) is holding back the performance of other parts. The problem has a name called a bottleneck. But, you should not worry about it because there is a tool that can help you to identify and solve these bottlenecks which are called bottleneck calculator. The tool can tell you which part of your computer is not working properly and which part is holding it back. By getting knowledge of these bottlenecks, you can upgrade or replace that part that needs it which will further lead your computer to run smoothly.

In this article, we will take a close look at the bottleneck calculator and will explain to you what it is, how it works, and how you can use it to enhance the performance of your computer. Grab a cup of coffee and let’s dive into the article.

Why am I getting these bottlenecks?

There are several factors in a computer that cause bottlenecks and identifying them is necessary. Some of the reasons for bottlenecks are mentioned below.

1. Outdated hardware

It is possible that you have older components in your computer and it is not able to keep up with modern software which causes crashes or slow performance in your computer.

2. Insufficient Power Supply

If you are not giving enough power supply to your computer components to run effectively, it will result in bottlenecks.

3. Software limitations

Certain programs have some demands and if your computer is not enough to provide these demands, it can lead to bottlenecks. It is possible that your computer doesn’t have enough ram or graphics card to run programs to run certain applications.

4. Overheating

If your computer is placed in a less ventilated area, it will cause overheating in components resulting in slow performance of the computer.

Fix using bottleneck calculator

A bottleneck calculator can help to solve these issues by identifying the particular component that is causing the error.

1. By Upgrading the affected component

If the problem is due to outdated hardware, the bottleneck calculator will suggest upgrading the affected components, such as CPU, GPU, or RAM. By upgrading these components, you can eliminate the bottlenecks and can enhance the performance of your computer.

2. By Upgrading the power supply unit

If the issue comes from the power supply unit, the bottleneck calculator will suggest you upgrade the power supply unit, and upgrading it means that you have to give your components enough power supply to eliminate the bottlenecks.

3. By Upgrading the RAM or graphics card

If you are getting bottlenecks from software limitations, the calculator will suggest you upgrade your RAM or graphics card to handle the software of the program. You can alternatively eliminate this issue by closing unnecessary programs or adjusting settings.

4. By ensuring proper ventilation

Overheating of components can become a reason for the problem you are facing and with the help of a bottleneck calculator you will get to know what you have to do. As it will suggest you clean your computer’s fans or vents, ensure that your computer is in a well-ventilated room, or upgrade your cooling system.

How does a bottleneck calculator work?

A bottleneck calculator is an online tool that is used to identify the component of the computer which is causing a bottleneck in performance. It works by analyzing the user’s input of software and hardware, and after that, it compares them to each other to determine which component is likely to get affected. It requires the user to input their specifications, such as CPU, GPU, or RAM and it uses this information to estimate the performance of the system and identify which system is lacking its performance. Some calculators also take into account the software application to give a more accurate analysis.

Once the bottleneck is identified the calculator will suggest a corresponding to it to improve the performance of your computer.

How to use a bottleneck calculator?

The process of using a bottleneck calculator is straightforward, you just have to follow the following steps mentioned.

Step 1:- Identify the specification of your computer components

The first step you have to do is to identify your computer components. You can get to know about the components by searching online or you can check the documentation which comes with your computer. The specification you have to identify is about the CPU, GPU, or RAM of your computer.

Step 2:- Choose a bottleneck calculator

There are different types of bottleneck calculators available online, such as the UserBenchmark calculator, the BeHardware bottleneck calculator, or the bottleneck calculator by PC-Build.com and it all depends on you which calculator you want to use.

Step 3:- Enter your computer specification

After the bottleneck calculator page opens up you have to enter the specifications of your components, such as GPU, CPU, or RAM by selecting from the drop menu and entering the amount of RAM.

Step 4:- Select the software application

The next step is to select the software application you want to test and some calculators will allow you to use specific software applications you want to test, such as video games, or a video editing program. This increases the accuracy of the analysis.

Step 5:- Interpret the results

The result will come out in percentage which shows the limiting components and a higher percentage means a higher need to upgrade the affected system.

What are the advantages and limitations of using a bottleneck calculator?

There are several advantages of using a bottleneck calculator and there are some limitations if it exists. All the advantages and limitations are given in the tabular form below.

1It helps to identify the weakest link in a computer system.It estimates the performance and does not give a real-life scenario.
2Helps to determine which component of the computer is to be upgraded to enhance performanceDoesn’t give an idea about the factors that may affect the overall speed of the system, such as software optimization or storage speed.
3Make it easy to decide in making hardware updatesShould not be relied upon solely for making hardware upgrade decisions.
4Can help users to save money.Accuracy may vary depending on the quality of the bottleneck calculator.
5Can be a quick and easy way to get an idea of system performance.May not be able to resolve the issue which is not related to bottlenecks.


In the end, we can say that a bottleneck calculator can be an incredible tool to identify and resolve the performance issue in your computer. It does it by getting input from you about your hardware and software and as result, it gives you a percentage of limiting components.
