Top 5 Best Bottleneck Calculators for Windows PC in 2023

We discuss PC bottlenecks and calculators in this post to help you spot them and update your CPU for sluggish performance.

Every computer contains a central processing unit (CPU) and graphics processing unit (GPU), which each have two cores. Each of these elements is essential to gaming. However, a lot of gamers claim to have experienced CPU or GPU bottlenecks. To a large extent, bottlenecking may be avoided by using the best bottleneck calculators.

But first, let’s briefly discuss the idea of bottlenecks before we look at the exhaustive list of the top CPU and GPU bottleneck calculators.

It will be simpler for you to select one if you know what bottlenecks are and how bottleneck calculators function to prevent them. So let’s first talk about it.

What Are GPU/CPU Bottlenecks, and How Do They Work?

A hardware component that places a limit on another hardware component is referred to as a bottleneck in the context of a computer. It prevents the cap element from operating to its fullest capacity. Bottlenecks typically result from the disparity in capability between two pieces of hardware.

Calculative operations and giving the GPU instructions for various tasks are handled by the CPU. The CPU becomes the GPU’s bottleneck if the GPU can supply these instructions quicker than the CPU can execute them.

Conversely, if the GPU executes the instructions more slowly than the CPU, the GPU becomes the CPU’s bottleneck.

The top PC bottleneck calculators assist in identifying your computer’s weak points and calculating its percentage bottleneck. It assists you in making the required modifications to your computer hardware to guarantee lag-free operation.

We can move on to the finest GPU and CPU bottleneck calculators now that you are a little more knowledgeable about bottlenecks.
Best CPU and GPU Bottleneck Calculators for 2023, listed in order

The PC bottleneck calculators listed below will provide you with a road map for selecting the best computing solution for optimum hardware performance.

1. Task Manager

Let’s start by using the computer’s built-in bottleneck calculator. The Windows Task Manager assists in locating the bottlenecks that can cause performance to suffer. Simply press the shortcut keys CTRL+SHIFT+DEL to launch the Task Manager, select the Processes tab, launch your preferred game, keep it running in the background, press the ALT and Tab keys simultaneously, and look at the CPU, disk, memory, and Internet utilization percentages. Any component that is 100% used signals a bottleneck.

2. PC Builds Bottleneck Calculator

The PC Builds Bottleneck Calculator is the next program on the list of the top ones for calculating bottlenecks. You can do the bottleneck test using just your computer’s CPU, GPU, and resolution using this simple online application. Additionally, it keeps track of your selections so that you may resume your selections the next time you visit this website.

Additionally, it asks what you use your CPU and GPU for the most so that it can perform computations more accurately. It also offers a few more features, like suggestions for improvements to boost device performance, an FPS calculator, an easy-to-understand bottleneck type display, and a choice to test your build for various activities.

3. MSI Afterburner

No matter if the topic is the finest overclockers for PCs or bottleneck calculators, MSI Afterburner is an unavoidable name. This software’s overclocker and hardware monitoring tool aid in maximizing your computer’s performance.

To check your CPU utilization by core, frequency, and temperature, utilize MSI Afterburner. Additionally, it enables you to monitor GPU and memory consumption. Unusual high levels might indicate a CPU or GPU bottleneck.

In terms of functionality, MSI Afterburner impresses consumers with a user-friendly interface, thorough hardware specifications, and great overclocking possibilities.

4. TechWafer Bottleneck Calculator

Bottleneck Calculator for TechWafer

Another top-notch CPU and GPU PC bottleneck calculator is now available online. Using this calculator, you must enter information about your CPU, GPU, and resolution in order to determine the bottleneck.

A score of less than 12% indicates that your PC is operating without any problems. A higher score, though, would be cause for alarm. Additionally, the program notifies you of the bottleneck-causing component so you may make the appropriate modifications.

5. CPU Agent Bottleneck Calculator

Let’s look at the CPU Agent Bottleneck Calculator right now. It is a straightforward tool that you may use to calculate bottlenecks. For an accurate bottleneck study, it simply needs to know the RAM speed, quality settings, and preferred display resolution you use when playing games.

After the examination is complete, the software presents a thorough comparison of your CPU with a sophisticated model to make the comparison process simple. Additionally, it aids in pinpointing RAM and gameplay bottlenecks at particular resolutions.

This one of the top CPU bottleneck calculators also has intriguing features like test performance in more than 80 games and thorough CPU benchmark data.

Questions and Answers

To help you understand bottleneck calculators and eliminate any ambiguity, we have included some frequently asked questions regarding them below.

How can you determine what is slowing down your computer?

To locate the bottlenecks, you may either utilize the Task Manager on your computer or one of the top bottleneck calculators included in this post.

How can I tell if my GPU or CPU is the bottleneck?

The CPU becomes the bottleneck as a result of GPU underutilization. You can suffer slowdowns if your CPU cannot keep up with the speed of the game. It’s referred to as a CPU bottleneck. While a GPU bottleneck occurs if your graphics card cannot calculate the number of photos per second as quickly as the CPU.

Q3: How should bottleneck results be interpreted?

You should be well-versed in computer hardware and its performance in order to comprehend the bottleneck results. If the GPU performance is 99-100% and the CPU performance is less than 99-100%, you could be dealing with a GPU bottleneck. Additionally, a CPU bottleneck occurs when the CPU performance is 99–100% and the GPU performance is below that threshold.

How may RAM bottlenecks be found?

If you want to see if your RAM is a bottleneck, examine the Task Manager. If RAM is being used at a fast rate or at 100%, not enough RAM is available to complete the work at hand.

5. Can a bottleneck harm a computer?

The computer is unharmed by bottlenecks. However, they reduce the performance of the gear, preventing it from reaching its maximum potential.

How may CPU and GPU bottlenecks be fixed?

The processor bottlenecks can be solved in a number of ways. To learn more about them, go through this comprehensive yet simple to follow tutorial.
