Bottleneck Calculator: What is it and How to Use it?

Due to advancements in technology, GPUs and CPUs are becoming extremely powerful. However, the power does come at a cost and hence, you need to maintain the balance between both of them. If one of them tends to pull up, you will see a significant performance drop from your device and can calculate it with a bottleneck calculator.

The same is explained by bottlenecking. Here, you will be comparing the GPU and CPU and check if both of them can co-exist to give a pleasant experience or not. You can also use the bottleneck calculator to check the compatibility. But before we see it actually, let us start by knowing what is bottlenecking exactly and how it occurs. 

Bottlenecking is not a new term. But if you are new in the field of PC building, you might want to acquaint yourself with this term. Bottlenecking in general terms is the capability to process per unit time. It is simple to understand the concept but might be difficult to control the actual procedure.

If there are 10 inputs and the capability of your system to process at a time is 1 input, bottlenecking will take place and the computer will slow down. As we said, it occurs due to the difference of maximum supporting capability of the two components.

Bottlenecking is natural. It is generally seen in many devices. Many people think it can cause serious damage and prove extremely dangerous for the PC but in most cases, it only slows down the PC. On some rare occasions, a serious threat can be faced, and hence, you need to calculate your scores and solve the issue. In modern computers, there are thermal sensors as well as throttling controls that process in accordance with the capability of the computer. This way, the computer is prevented from getting slowed down. 

Tech professionals generally calculate the scores prior to the installment of hardware so that they can know which CPU and GPU are able to co-exist hassle-free. CPU Bottleneck Calculators can help you in building up a device. Certain calculators will also let you install virtual CPUs and GPU to measure the difference in performance. The performance gap is generally one of the most vital reasons for bottlenecking. The calculators are not 100 percent accurate but can be extremely precise and a misjudgment is a rare occasion. 

There are several bottleneck calculators in the market that you can use to measure the performance gap and know which components will sync well together. Even if you are building a workstation or are going after a strong PC build, these bottleneck calculators are surely going to help you out in selecting the components.

Let us check out a few of them.

PC Build’s Bottleneck Calculator

PC Build’s Bottleneck calculator is simple and easy to use. Once you enter the relevant component details, you have to click on the “Calculate” button. Once you have clicked on calculate, the Bottleneck Calculator will check which component is majorly significant in the functionality of your system and by what percentage. 

It will also display which constituent is not performing up to the mark. Due to the user-friendly interface, many users prefer PC Build’s Bottleneck Calculator. There is also an option for advanced bottleneck calculation, which acts as a bonus for the users. 

First, in the calculator, you will be displayed two tabs. One for AMD and one for Intel. Choose the respective tab as per your processor. Nextly, you will be asked to choose your GPU. Again, two options will be displayed: one for Intel and another one for AMD. You need to choose the exact GPU series so that precise calculation can be done. The last option will be to choose the RAM memory. Choose the RAM memory and click on Calculate. 

It also provides an additional advanced feature where you can set the CPU as well as GPU’s clock speed percentage. By default, it is kept as 100 percent which you can modify as per the requirement. 

CPU Agent Bottleneck Calculators

Another Bottleneck Calculator which is also amazing to work with is the CPU Agent Bottleneck Calculator. You need to begin by providing the input of your components. Then, click on submit so that the calculator performs the operation and then, click on Reveal results to get your results displayed on the screen.

If you feel the bottleneck percentage is quite out of bound, you can think of replacing the component that has a major impact on the performance. It also has a feature that suggests places to buy the component, which is unique in itself and can prove to be extremely useful. However, such advanced features might slow down the calculation so you would have to wait for a while for the results to show up. 

Here, you will be asked to select your CPU as well as GPU of Nvidia or AMD from the drop-down list. Nextly, you will be asked to choose your RAM size from the drop-down menu. It also has other features to display the FPS as well, so you would need to enter your resolution as well as quality settings to ensure you receive the most accurate results.

People often feel stressed when they hear about bottlenecking. Well, bottlenecking is not damaging your device in most cases but yes, we need to stay aware and check regularly whether it is impacting the performance of the device on a high level or not. Apart from that, the bottleneck calculators are mostly precise and will give you the most appropriate results. Some calculators are free to use while some are paid. It all narrows down to your personal opinion at last. 

That was about all about bottlenecking and bottleneck calculators. The CPU bottleneck calculator is a simple and easy-to-use tool and can help you decide whether the components will be a good fit for your build or not. Make sure you put the components appropriately to get precise results.
