Frequently Asked Questions
Find answers to common questions about CPU and GPU bottlenecks, our calculator, and how to optimize your system performance.
About Bottlenecks
What is a CPU/GPU bottleneck?
A bottleneck occurs when one component (either CPU or GPU) limits the performance of the other. For example, if your CPU can't process game data fast enough, your GPU will be underutilized, resulting in lower performance than the GPU is capable of.
How do I know if I have a bottleneck?
Common signs include: one component running at 100% while the other is underutilized, lower performance than expected, stuttering or inconsistent frame rates, and performance not improving with graphics settings changes.
Are bottlenecks always bad?
No, some level of bottlenecking is normal and unavoidable. The goal is to minimize significant bottlenecks that impact your specific use case. A minor bottleneck (under 10%) is generally acceptable.
Using Our Calculator
How accurate is the calculator?
Our calculator uses real-world benchmarks and performance data to provide accurate estimates. However, actual results may vary depending on specific use cases, background processes, and other system components.
What does the bottleneck percentage mean?
The bottleneck percentage indicates the potential performance limitation. A higher percentage suggests a more significant imbalance between your CPU and GPU. For example, a 20% CPU bottleneck means your GPU's performance is limited by approximately 20% due to CPU constraints.
How often is the component database updated?
We regularly update our database with new CPU and GPU releases, typically within a week of launch. Performance data is continuously refined based on real-world benchmarks and user feedback.
Performance Optimization
How can I reduce a CPU bottleneck?
You can: close background processes, update BIOS and drivers, enable XMP/DOCP for memory, consider CPU overclocking if supported, and optimize Windows power settings. In some cases, upgrading to a newer CPU might be necessary.
How can I reduce a GPU bottleneck?
Common solutions include: updating graphics drivers, adjusting in-game graphics settings, ensuring proper GPU cooling, considering GPU overclocking, and using features like DLSS or FSR when available.
Which component should I upgrade first?
Generally, upgrade the component causing the bottleneck first. Our calculator will identify which component is limiting performance and provide specific upgrade recommendations based on the analysis.
Technical Considerations
Does resolution affect bottlenecking?
Yes, higher resolutions typically shift more load to the GPU. A CPU bottleneck is more common at 1080p, while 4K gaming is usually GPU-bound regardless of CPU power.
How do different games affect bottlenecking?
Different games stress components differently. CPU-intensive games (like strategy or simulation games) are more likely to cause CPU bottlenecks, while graphically demanding games tend to be GPU-limited.
What role does RAM play in bottlenecking?
Insufficient RAM or slow RAM speeds can create a memory bottleneck, affecting both CPU and GPU performance. We recommend at least 16GB of RAM and enabling XMP/DOCP for optimal performance.
