Best Bottleneck Calculators

CPU bottleneck occurs especially a lot for gamers and other users of special software which require lots of process resources on the computer.

What is a CPU bottleneck?

In the computer, when the CPU reaches the maximum limit of its power and could no longer accept more processes the bottleneck problem happens. The issue is that it could make important parts of the computer, such as GPU, not work well because they are limited by the processor.

The problem could occur due to a number of reasons.

For example, while gaming, CPU is responsible for a lot more than just rendering the game graphics which is usually done with GPU help. These tasks which use the capabilities of the processor include the UI, physics, game logic, game sound and AI processing.

So, as you could see here, compared to GPU, CPU has to do lots of things.

In simple terms, if the data which should be prepared for the GPU to be processed isn’t ready by CPU in time that GPU is ready to process new data, then we say that the CPU is bottlenecking GPU.

This all could cause the framerate to drop during the gameplay, which is very annoying for gamers.

How to solve the issue?

The short answer would be to buy a more powerful CPU. But how should you know that the CPU you want to buy matches the GPU?

That’s when bottleneck calculators could come to help.

These nice gaming tools could help you decide if your selected CPU and GPU could work alongside each other to give you an enjoyable and smooth gaming experience.

This could help a lot especially when playing games like GTA 5 which requires lots of CPU resource in addition to a powerful graphic card.

1) PC Builds bottleneck calculator

The first option we recommend to gamers for calculating their possible CPU/GPU bottleneck is the calculating tool developed by PC Builds website.

This tool has a simple and intuitive interface which offers necessary information you’re looking for regarding your gaming hardware.

In order to use this calculator just follow these simple steps:

  • Choose your CPU brand (Intel/AMD) from the options and then select the model (such as Core i9, i7, etc.)
  • Now, select the brand of your GPU (AMD/NVIDIA) and then choose its model from the list (e.g. GeForce RTX 2080 or Radeon RX 580)
  • Enter the size of RAM memory
  • It’s optional but you could tick the box next to advanced settings and configure CPU or GPU clock percentage for more accurate results.
  • When everything is done, you could hit the Calculate button.

After a short amount of time, the result would be provided which is very clear and detailed.

2) GPU Check comparison tool

This online tool could also help you learn more about the power resources and other detailed options provided by graphic cards.

But, unlike the previous tool this is more than a comparison tool for GPUs than the match between different CPUs and GPUs.

But in any case, this could be helpful in some occasions.

Other solutions for bottleneck

As we all know, that might not be possible mostly due to budget reasons.

The next best options would be to somehow make the CPU run faster. This could be done much easier in CPUs which support faster RAM speeds and overclocking.

You could try these items in order to have a faster CPU and hence faster gaming experience:

  • Keep your system clean: just close all the unnecessary processes and software running in the background of your system – which could be done using Task Manager in Windows.
  • Make your RAM faster
  • Try CPU overclocking (with caution)
  • Optimize the CPU settings in the game: tweak game options such as texture, shadow, resolution, etc. to get better results.
