Bottleneck Calculator

Detect CPU-GPU bottleneck in PC builds.

How It Works

  1. Enter CPU & GPU scores. Use benchmark scores or pick presets from the hardware block.
  2. See bottleneck type. The main result shows whether CPU, GPU, or neither limits performance.
  3. Set resolution & RAM. Choose 1080p/1440p/4K, RAM, storage, and workload (gaming, editing, streaming).
  4. Analyze balance. Get bottleneck %, severity, and CPU/GPU utilization estimates.
  5. FPS & upgrades. View estimated frame rates and upgrade suggestions for your build.

Higher resolution shifts load toward the GPU; lower resolution favors the CPU.

Enter values to see results.

Formula & Reference

Bottleneck % ≈ CPU/GPU balance adjusted for resolution, RAM, and workload
