What is a Bottleneck?
A bottleneck in a computer is a system-restrictive slot where a part of your computer’s hardware limits the other, resulting in slowing down everything else. It actually refers to the mismatched component domain where a strong component is set at a slower pace than the weaker one and affects the overall performance of your PC. No matter how expensive the parts you are using or how much you are spending on your PC optimization, you can still face low FPS, loading, or lagging errors if the mismatched domain is recurring in the form of a bottleneck that could be of the following types.

Types of Bottleneck
There are various types of bottlenecks that you may encounter while using your PC, and some of the most common types are as follows:
RAM Bottleneck
If your device’s memory is incompatible with the working system, then this mismatch can result in a Bottleneck error that causes long loading intervals and performance limitations.
GPU Bottleneck
It is one of the common Bottleneck errors that mainly appear due to the mismatch of the graphics cards with the GPU, and as a result, laggy visuals with low frame rates appear.
CPU Bottleneck
Slow data feeding from GPU to CPU causes this Bottleneck error that results in frame rendering and lower FPS domain.
Thermal Bottleneck
Thermal Bottleneck is also the most common Bottleneck error that appears due to the slow cool-down system and fast heat-up, resulting in slow-paced working and throttling.
Display and Storage Bottleneck
Last but not least, we have the display and storage Bottleneck errors that also result in software loading and waste of the high-frame rates.

Bottleneck Calculator Key Factor
Bottleneck Calculator is the leading tool that successfully estimates the performance-rendering attributes in your PC by comparing all its components that are taking part in limiting its performance. There are various components that partake in this Bottleneck error, and to help you learn all about them we have covered them below. So, let’s explore these bottleneck-causing components and master all the correlated slots.
RAM
One of the core factors in your PC upon which the task-efficiency rely is RAM. It plays a key role in storing and utilizing the required data that is needed to perform a task. It also covers the overall performance of your PC, improving the delayed responses that are initiated due to the DDR3 and DDR4.
CPU
CPU, or the central processing unit, is another key factor of the PC that is also known as the brain of your computer, upon which the data flow is executed. It is the main operator that performs all the arithmetic tasks by enticing, decoding, and performing multiple tasks.
GPU
Next, we have the GPU, the Graphic Processing Unit, which is also a potent component of the PC. It is the main circuit that is known for processing complex data from images to videos, and is well known for the parallel processing domain. It is also the main hub for scientific computing with a silicon chip that works great in relation with CPU.
Screen Resolution
Your screen resolution also remains a core factor in Bottleneck error, as high-resolution power slots demand a powerful GPU, which means a heavy load on the computing system, which is then signified with errors like lagging and loading. So, resolution power like 4k is struggling as compared to 1080p.
SSD/HDD Storage
One of the most common Bottleneck slots is storage, and most commonly, the HDD storage. The solid-state drive is lighter than the HDD, referring to a smooth performance of the PC while the other one remains heavy and causes lags and longer loading intervals.
Cooling System
The performance of your PC is also heavily dependent on the cooling system, which is meant to cool down all the built-in components in your PC to maintain a smooth and fun-paced working environment. If the cooling system is not working properly, the components get heat-up causing an instant crashing and lagging error.
Power Unit
Another major cause of the Bottleneck error is the weak power supply unit, which often results in system crashes and long-run loading errors. It is the main domain upon which the major tasks like energy supply rely, and that is only possible if you are using a highly powerful power supply unit.
