Many people who construct their computers or buy them from stores don’t realize that all of the components must function together to achieve maximum performance. If you’re a gamer, this means that all of your components are cooperating to bring your game to life on the screen. I’ll describe How To Tell If CPU Is Bottlenecking GPU?

As the name implies, a Bottleneck arises when the amount of data delivered for processing or the amount of data that can be processed at the same time is limited. In other words, the ability to return processed data is insufficient in comparison to the amount of data sent for processing.

The CPU (processor) and GPU (graphics processing unit) are the components included in the Bottlenecking Process (graphics card). A bottleneck will occur if the processing speeds are vastly different. We’ll go over the processes in further depth.

How To Tell If CPU Is Bottlenecking GPU?

You should focus on “CPU Impact on FPS,” which should be 10% or less. This number will indicate whether a bottleneck is caused by a CPU and GPU mismatch and whether upgrading either component will fix the problem.

CPU Bottleneck

A CPU bottleneck occurs when the processor is unable to process and transfer data quickly enough. Consider an AMD A6 5th generation processor with a GTX 1080 Ti graphics card as an example. On paper, a GTX 1080 Ti should be able to handle games with increased graphical details with ease.

However, a CPU bottleneck occurs when the A6 processor cannot keep up with the graphics card’s processing performance. The CPU is in charge of processing real-time game activities, physics, user interface, audio, and other CPU-bound functions. If the data transfer speed is limited, a bottleneck occurs. For a clearer visual illustration of what happens when a CPU bottlenecks, see the figure below.

GPU Bottleneck

The GPU bottleneck is the same idea, except it occurs when a fast processor is paired with a low-end graphics card. Let’s use an Intel Core i7-8700K processor with a GeForce GT 1030 graphics card as an example. The Core i7 processor is without a doubt capable of processing games quickly. It processes at such a quick rate that the GT 1030 is unable to return the processed data.

How To Know If CPU Is Bottlenecking GPU?

You will be “bound” when building a gaming PC. There are two types of GPU-bound and CPU-bound systems, with the GPU or CPU acting as the limiting component in your configuration. Many people know that one of these limiting variables will be present when they design their computer.

For any game, there is no such thing as a perfect CPU-GPU balance. Because some games aren’t well-optimized, they can cause the CPU to be slowed down. Some games do not support SLI, which means that even if two graphics cards are used, the game would still function poorly.

Are Bottlenecks Universally Bad?

Answer: No! Any system will nearly always have a bottleneck. It’s quite rare for a computer to be properly balanced in every condition, with each component operating at maximum efficiency. So the question isn’t whether there is a bottleneck, but if the degree to which the weaker components restrict things is a problem.

It’s scarcely a problem if your CPU only allows you to make use of 98 percent or 99 percent of your GPU’s maximum speed. You’ve money wasted on hardware performance you can’t reach without yet further upgrade if you’re only getting 70% of your GPU’s capability due to a slow CPU.

If your new GPU is supplying 100% but your CPU is only 50% used, you might have hooked up a quick card and gotten even better results. However, because we typically use our computers for purposes other than playing video games, this condition is less of an issue.

As a result, you’ll continue to profit from the extra CPU capacity for other programmers. Not to mention the ability to run extra background operations without interfering with game performance. In a nutshell, GPU Bottlenecking is beneficial, and CPU Bottlenecking is negative.

Can A Motherboard Bottleneck A GPU?

In summary, a motherboard CAN impede a GPU. However, the particular motherboard component that is the bottleneck is a particular interface called PCIe and the related PCIe slots, not the entire motherboard. The motherboard has two potential bottlenecking effects on your GPU.

Is My CPU Bottlenecking My GPU?

If your CPU is preventing your GPU from performing to its maximum potential, your CPU is of a lower caliber and is the bottleneck. You’ll see a significantly higher CPU utilization than GPU when your CPU is the problem. This indicates that your computer can’t utilize more of the GPU because the CPU can’t operate at a higher level.


That’s all about How To Tell If CPU Is Bottlenecking GPU? Both the CPU Bottleneck and the GPU bottleneck are concerned with the same platform. A bottleneck is frequently caused by a bad processor and graphics card combination.

This is why gamers must first pair the appropriate components before purchasing them. To avoid having to update too soon, choose components that are compatible with the games you typically play. The odds of the suffering bottleneck are small if the correct components are combined.

Frequently Asked Questions

Is it a bad thing if you’re CPU slows down your GPU?

You simply cannot get additional performance out of your GPU or CPU if they are the bottleneck. That is all there is to it. There is always a bottleneck in any system; it’s a simple fact. The goal is to strike a good balance while building a computer, such as not using a slow CPU with a fast GPU or vice versa.

Is it preferable to bottleneck the GPU or the CPU?

In essence, the CPU determines the maximum frame rate dependent on the game. Depending on the game and resolution, the GPU determines the maximum frame rate. And, as long as your maximum frame rate is higher than the refresh rate of the display you’re using, a bottleneck isn’t a big deal in the games you’re playing.

When a CPU becomes bottlenecked, what happens?

Performance bottlenecks can cause a server or computer that is otherwise functional to slow down to a crawl. The word “bottleneck” refers to an overburdened network as well as a state of computing equipment in which one component is unable to keep up with the rest of the system, causing overall performance to drop.

Does it matter if the GPU has a bottleneck?

It won’t reach its full potential, but it won’t be any worse than any other card. No matter what card you use, it will perform to the best of its ability. You’ll reach a point where downgrading cards will result in a reduction in performance.
