What are CPU/GPU Bottleneck?

What is the bottleneck?

Bottlenecks can be generally defined as an aspect of something that limits its potential. That’s exactly what bottleneck is, in the context of your computer. It is when a certain system component reaches it maximum capacity that other components have to wait for them to be freed up before they are able to function again at full capacity again. This creates a kind of traffic jam for data within your computer because only one thing can be done at a time until all backlogged components free up their usage. For example, if you have an old CPU but you have a high-end graphics card, there may come a point where the graphics card is waiting for the CPU to give it more work so it can do what you want it to. This is a bottleneck.

What are the most common bottlenecks?

There are many different potential bottlenecks in your computer, but some are more common than others. One of the most common is when your graphics card is being held back by your CPU. If you have a high-end graphics card but an old or slow CPU, that can create a bottleneck. Another common bottleneck is when your storage device (like your hard drive) can’t keep up with the speed at which data is coming in from your other components. So if you have a high-end graphics card and a new fast CPU but an old, slow hard drive, that would be another bottleneck.

How do I identify what my bottleneck is?

The easiest way to tell if you have a bottleneck is to see what happens when you stress test your computer. To do this, you need a program that will simulate other programs running at the same time as a game. This simulator can be a standalone program or one built into certain benchmarking utilities. One popular free program is called Furmark and it’s used for stress testing GPUs . If your FPS (frames per second) drops dramatically while using this, then that means your graphics card is being held back by something else such as your CPU or storage device not being able to keep up with data demands.

What should I do about my bottleneck?

If it turns out you do have a bottleneck and aren’t happy with the speed of your computer, then you have a couple options. The first is to upgrade what’s slowing your computer down. If it’s a CPU bottleneck, get a new fast CPU. If it’s a GPU bottleneck, get a new high-end graphics card. It’s important to remember that bottlenecks can change over time so don’t be discouraged if the bottlenecks are different now than they were when you bought your components.

The second option is to buy an entirely new computer designed specifically for the kind of work you want to do with it. For example, most gaming PCs are built just for gaming and won’t perform as well at video editing or 3D rendering as something more targeted toward those tasks would. This way you can make sure all your components are ideal for what you want them to do without having to worry about future bottlenecks.
