CPU and GPU bottlenecks happen when the performance of one or both of these parts slows down the whole computer. This can occur if the CPU or GPU isn’t powerful enough to meet the system’s needs or if one part of the system is significantly faster than the other and must wait for it to catch up. These bottlenecks can be identified using our bottleneck calculator.
This is called a CPU bottleneck when the CPU can’t process data as quickly as the rest of the system, which stops the flow of information. This could be due to the CPU being old, having insufficient power compared to the rest of the system, or having too many tasks to handle concurrently. In this case, the bottleneck can be fixed by upgrading the CPU or cutting the amount of work the system needs.
On the other hand, a GPU bottleneck happens when the GPU can’t process graphical data fast enough to meet the system’s needs. This could be due to the GPU being old, not having enough power, or the system not being configured to take advantage of what the GPU is capable of. In this case, you can improve performance by upgrading the GPU or fine-tuning the system settings.

How much is Bottleneck acceptable?
The bottleneck calculator assesses the degree to which a bottleneck exists in a computer system. A score of less than 7 indicates that the system does not significantly impact CPU and GPU performance and is therefore functioning efficiently.

How Much is too Much Bottleneck?
A score above 7% can significantly decrease the efficiency of a system, while a score above 20% generally causes an unnecessary bottleneck.
The main problem with having too many points is that it can cause the system to become overloaded and move much more slowly. As a result, tasks that should take seconds or minutes may take much longer than expected, resulting in decreased productivity and user frustration. Also, high scores may mean that the system needs more hardware to handle the extra load, which can be expensive and hard to manage.
Systems Recommendation without Bottleneck Problem
Avoiding performance bottlenecks in a PC build requires careful planning. When picking the parts, it’s important to ensure their skills and jobs are a good fit. These few PC builds do not have bottlenecks and work exceptionally well together.
