Key notes

  • Bottleneck calculators are essential for monitoring PC performance and for planning your next upgrade.
  • Due to various factors, sometimes these tools aren't the most accurate, and your results can vary.
  • If you're a beginner, then this software should give you a vague idea of your hardware bottlenecks.
bottleneck calculator software

Bottleneck calculator software is a tool for analyzing the performance of the computer processor and graphics card.

It checks for the speed between the CPU and GPU to analyze their compatibility and the reasons for the PC bottleneck.

Meanwhile, a bottleneck is a situation that occurs when there is a disparity between how much data is being sent for processing and how much data can be processed at the same time.

Often, a bottleneck occurs from a wrong pairing of the processor (CPU) and graphics card (GPU). Simply put, one of the components is too old or incompatible with the others.

Hence, it causes a slowdown in data processing and reduces computer performance. To keep track of your hardware, you should consider using reliable resource monitor software.

Are bottleneck calculators accurate?

While bottleneck calculators are usually simple to use and user-friendly, they are not accurate. They mostly give you estimate of your PC bottleneck and nothing more.

The reason for this is that it hard for bottleneck calculator online or offline to take in consideration some of the little things that can determine how much of aa bottleneck some parts can cause.

Hence, the best they do is to give an estimate of potential causes of bottlenecks.

What is a good bottleneck percentage?

According to popular opinion, anything below 10% is a good bottleneck percentage as this does not really impact your FPS. Anything higher than this value can be considered high and you will start noticing the impact.

MSI Afterburner – Easy to use

MSI Afterburner is overclocking software that lets you get the maximum performance out of your hardware. Since overclocking is potentially dangerous, the software comes with a hardware monitoring tool.

With it, you can easily monitor CPU usage by core, clock, and temperature. This also applies to your memory and GPU. If you notice anything suspicious, such as unusually high values while gaming, it’s possible that you’re dealing with a bottleneck.

Although the purpose of MSI Afterburner isn’t to work as a bottleneck tester on your PC, advanced users can use it to determine which component is affecting their performance.

Key features:

  • Simple user interface
  • Ability to view detailed hardware specifications
  • Great overclocking features
  • Detailed hardware monitor

How do you manually check what is bottlenecking your computer?

  1. Open a game or any app whose performance you expect to lead to bottlenecking.
  2. Close other apps and background processes.
  3. Now, press the Windows key + X and select the Task Manager option.

  4. Click the Performance tab at the top.

  5. From here, check if any of the CPU, GPU, Memory, or Disk hits 100% consistently for a long period of time.

If any of your core PC components hits maximum value for a long time, then it is the cause of bottlenecks on your computer.

How to check if CPU is Bottlenecking My GPU?

Normally, the GPU performance should be pegged at 99-100%, with a CPU below 99-100% to be considered a good GPU bottleneck.

However, if the CPU is at 99-100% of full utility while the GPU runs below 99-100%, then the CPU is bottlenecking the GPU.

But this will depend on the game you are playing and your settings and resolution.

How do I interpret bottleneck results?

Bottleneck software isn’t always correct, but it can give you a vague idea of what is causing the slowdown on your PC.

When it comes to numbers, take them with a grain of salt since they aren’t the most accurate representation of an actual CPU or GPU bottleneck.

Instead, focus on researching the component that is causing the bottleneck. Analyze its performance and bandwidth speed, and make that all other components can match its bandwidth speed.

This isn’t always the most straightforward task, because it requires you to have a solid understanding of PC hardware and its performance.

How do I know if my RAM is bottlenecking?

One way to find out if your RAM is bottlenecking is to check the Task Manager. If your RAM utilization is high or 100%, you don’t have enough RAM for the current task.

Also, check your CPU and motherboard frequencies and ensure that the maximum supported frequency matches your RAM’s working frequency.

Can bottleneck damage your pc?

No, a bottleneck won’t damage your GPU or any other hardware. When a certain component encounters a bottleneck, it won’t give maximum performance.

This isn’t a problem; in most cases, it will lessen the strain on your hardware.

Now that you know all there is to know about bottlenecks, let’s see the best online bottleneck calculator.

These are the best calculators for bottleneck analysis available right now. All of them with a similar approach with slight differences in features.

A quick tip to confirm the legitimacy of their result is to examine the Task Manager while actively running the high-end apps that cause your PC to bottleneck.

Our guide on fixing high CPU and low GPU usage may be helpful to you if you want to troubleshoot the problem.
