GPU + CPU Bottleneck Calculator

Shows exact bottleneck percentage and the perfect CPU upgrade (or confirms you’re already golden). It factors in real raw data across dozens of CPU and GPU models so we can try to make this tool work for as many users as possible. If you do not see your exact model in the dropdown options pick one that is most similar in specifications. We update this tool regularly for the frequently new models that are released.

• Great for any PC user dealing with GPU/CPU bottleneck issues or may need troubleshooting to determine whether you have a bottleneck issue
• Best for PC gaming as GPU/CPU bottlenecks are one of the most common causes of poor gaming performance

We take exact specs of your PC's hardware and use real data to provide bottleneck calculations. Limitations include the lack of other hardware details or software issues/settings that may be contributing to poor performance or bottleneck problems, so this tool is based purely on raw specs and data. More limitations are out of date CPU and GPU options, or lacking your exact model in the choices, try to pick the most alike model.

Here is a sample Output for a user with a RTX 3080 Ti + i5-14400F, they are gaming at 1080p with a target fps of 240Hz and playing eSports titles.

Performance Analysis: RTX 3080 Ti + i5-14400F

1. Bottleneck Percentage

• CPU Bottleneck: 15%
• GPU Bottleneck: 0%

Conclusion

• Total Bottleneck: 15% (CPU)

2. Upgrade Recommendation

• Upgrade to: i7-13700K or i9-13900K
  • This will help eliminate the bottleneck and fully utilize the RTX 3080 Ti for optimal performance.

3. Performance Summary

Real-World FPS Examples (2024-2025 Games)

• CS2: 180-240 FPS
• Valorant: 240+ FPS
• Overwatch: 200-240 FPS

Final Thoughts

The combination of the RTX 3080 Ti and i5-14400F is solid for eSports at 1080p, but to consistently hit 240 FPS in competitive titles, a CPU upgrade is recommended to fully leverage the GPU's capabilities.

The Tool Collective team are Tech gearheads, and avid PC gamers. Most of us had to deal with a GPU/CPU bottleneck in the past, and we know how frustrating it can be, especially when you didn't take the time when purchasing your PC or building it to ensure bottleneck probability was kept to a minimum. We are here to solve that for you with this free tool so you never have bottleneck issues again. We took extra time with this tool, as for it to be effective, we had to be sure to include as many GPU or CPU models as possible, so we hand picked that most common models one by one. We hope to stay on top of this tool and keep updating it as new products come out.

Made with The Tool Collectives signature model. We layout all factors required to make the best possible decision for this particular question and construct the inputs and choices accordingly. We then build a custom system prompt that incorporates logic if needed and clear output criteria. We then use an AI engine to power the tool, resulting in expert human crafted responses, designed by real enthusiasts.
