GPU Bottleneck Calculator
Estimate whether your CPU or GPU is the bottleneck in gaming.
Balance your components for best performance.
Bottleneck Analysis
Bottleneck occurs when one component limits another from performing at full potential.
How to detect a bottleneck:
- If GPU usage is near 100% and CPU is low → GPU bottleneck (upgrade GPU)
- If CPU usage is near 100% and GPU is low → CPU bottleneck (upgrade CPU)
- If both are near 80–95% → Well balanced system
Factors that affect bottleneck:
| Factor | Affects |
|---|---|
| Resolution | Higher res → more GPU load |
| Game type | Strategy/sim → more CPU |
| Frame rate target | Higher FPS → more CPU load |
| Settings quality | Higher quality → more GPU load |
This calculator provides a simplified estimate based on component tiers and resolution.
