Bottleneck Guides & Articles
Learn how to optimize your PC performance and understand bottlenecks
Tips for Best Results:
- Select your exact CPU and GPU models for accurate results
- Check the calculator before upgrading your components
- Consider your gaming resolution when choosing components
- Balance is key - neither CPU nor GPU should be severely limited
- RAM and storage type also affect overall system performance
Understanding Bottleneck Percentages:
- 0-5%: Excellent balance, no significant bottleneck
- 5-15%: Good balance, minor bottleneck acceptable
- 15-30%: Moderate bottleneck, consider upgrading
- 30%+: Severe bottleneck, upgrade recommended
Frequently Asked Questions
A bottleneck occurs when one component in your PC limits the performance of another component. For example, a weak CPU paired with a powerful GPU can prevent the GPU from reaching its full potential, resulting in lower gaming performance.
Our calculator provides estimates based on benchmark data and performance scores. Actual bottlenecks can vary depending on specific games, settings, and workloads. Use this as a general guide for system balance.
No! A small bottleneck (under 10%) is normal and expected. Perfect balance is nearly impossible and unnecessary. Focus on keeping bottlenecks under 15% for optimal gaming performance.
Yes! Higher resolutions (1440p, 4K) put more load on the GPU, while lower resolutions shift the load to the CPU. A GPU bottleneck at 4K is actually preferred for most gamers.
Not necessarily. Consider your budget, gaming needs, and current performance. If you're happy with your FPS, a moderate bottleneck is acceptable. Upgrade when you need more performance.
