PC Bottleneck Calculator
Check if your CPU bottlenecks your GPU — free, instant, no signup.
How it works
- 1
Pick your CPU and GPU
Searchable lists cover popular AMD Ryzen, Intel Core, NVIDIA, Radeon, and Arc parts.
- 2
Choose a resolution
1080p stresses the CPU more; 1440p and 4K shift load toward the GPU.
- 3
Read the estimate
You get a bottleneck percentage, a plain-English verdict, and an upgrade hint when the gap is worth fixing.
Each CPU and GPU has a relative gaming-performance score derived from aggregated public benchmarks (top parts sit near 100). We apply a resolution weight — CPU influence is full at 1080p, reduced at 1440p, and lower still at 4K — then compare effective CPU strength to GPU strength. The gap becomes the bottleneck percentage. These are estimates, not lab measurements of your specific system.
