Building or upgrading a PC can be a lot of fun, but it’s important to make sure all your components work well together. A common issue that can slow down your system is a bottleneck, where one part of your PC holds back the performance of the others. To help you avoid this, we will look at the seven best bottleneck calculators for PC in 2024.
Understanding Bottlenecks in PC Components
What is a Bottleneck?
A bottleneck in a PC occurs when one component is significantly slower than the others, causing a decrease in overall system performance. For instance, pairing a powerful GPU (Graphics Processing Unit) with a weak CPU (Central Processing Unit) can result in the CPU being unable to keep up with the GPU, leading to a CPU bottleneck. Bottlenecks can manifest in various ways, including slower load times, lower frame rates in games, or overall sluggish system performance.
Types of Bottlenecks
- CPU Bottlenecks: These occur when the CPU is too slow to process data as fast as the GPU can render it, leading to reduced performance, particularly in gaming and multi-threaded applications.
- GPU Bottlenecks: These happen when the GPU is unable to keep up with the processing demands of the CPU, leading to underutilization of the CPU’s potential.
- Storage Bottlenecks: Slow storage devices like HDDs can cause delays in data retrieval, slowing down the system.
- Memory Bottlenecks: Insufficient or slow RAM can hinder multitasking and data processing, leading to system slowdowns.
Identifying Bottlenecks
Identifying bottlenecks involves analyzing your system’s performance in real-world scenarios or through benchmarking tools. Using a PC bottleneck calculator simplifies this process by providing estimates of potential bottlenecks based on your selected components.
Importance of Bottleneck Calculators
A bottleneck calculator is essential for anyone looking to build or upgrade a PC. Bottleneck calculators help ensure that your components are well-matched, leading to a smoother and more efficient system.
Time-Saving
Using a PC builds bottleneck calculator can save you significant time by quickly identifying potential component mismatches, allowing you to make adjustments before you even purchase the parts.
Cost-Effective
By using a bottleneck PC calculator, you can avoid overspending on components that won’t deliver the desired performance, helping you allocate your budget more effectively.

How to Use Bottleneck Calculators
Gathering System Information
Before using a PC builder bottleneck calculator, gather detailed information about your PC components, including the CPU, GPU, RAM, and storage.
Running Benchmarks
Run benchmarks on your system using a CPU bottleneck calculator or GPU bottleneck calculator, such as UserBenchmark or Cinebench. These tools simulate real-world scenarios to provide performance metrics for each component.
Analysing Results
Review the benchmark results to identify any potential bottlenecks. Look for areas where one component significantly outperforms others, indicating a bottleneck.
Factors Affecting Bottlenecks
Understanding the Relationship
The relationship between the CPU and GPU is crucial in determining bottlenecks. A powerful GPU paired with a weak CPU can lead to a CPU bottleneck, while the opposite scenario can cause a GPU bottleneck. Understanding this balance is key to creating an optimised PC build.
Other Factors
Storage Speed
Slow storage devices like HDDs can cause bottlenecks by delaying data retrieval. Upgrading to an SSD can significantly improve performance and reduce bottlenecks.
Power Supply
An inadequate power supply can limit your components’ performance, leading to instability and potential bottlenecks. Ensure your power supply can handle the demands of all your components.
Cooling System
Insufficient cooling can lead to thermal throttling, where components reduce their performance to avoid overheating, creating bottlenecks in your system.

FAQs
A 28% CPU bottleneck indicates that the CPU limits the system’s performance by about 28%. While not catastrophic, this bottleneck level can lead to noticeable performance issues, especially in CPU-intensive tasks or gaming. It’s generally better to aim for a lower bottleneck percentage.
The biggest bottleneck in a PC typically comes from the CPU or GPU, depending on the system’s configuration. If one of these components is significantly weaker than the other, it can limit the PC’s overall performance, especially during demanding tasks like gaming or video editing.
Achieving a 0% bottleneck is impossible, but you can minimise it by carefully balancing your CPU and GPU performance. This involves selecting closely matched components in terms of performance capabilities, optimising system settings, and ensuring other components like RAM and storage are sufficient for the tasks you intend to perform.
A 10% bottleneck is relatively minor and usually won’t result in significant performance degradation. This bottleneck level is generally acceptable, especially if you must push your system to its absolute limits.
Yes, if your CPU is consistently at 100% usage, it indicates a bottleneck. The CPU is maxed out, which can cause slower application performance, particularly in scenarios where the GPU is underutilised because the CPU can’t keep up.
A 5% CPU bottleneck is minimal and generally considered good. It suggests that your system is well-balanced, with only a slight performance limitation that should not significantly impact most tasks.
