CPU GPU Bottleneck Calculator: Build a smarter PC.
Match your CPU and GPU, size your power supply and estimate electricity costs. Real-world context for better gaming PC decisions, without fake-precise bottleneck scores.
CPU & GPU Bottleneck Estimator
Choose your components, resolution and gaming style to see what to investigate before upgrading. Exact bottleneck claims require measurements, so this preview does not manufacture a CPU/GPU percentage.
Configure your build
Find your likely limiting factor.
Choose a CPU, GPU and scenario to view a practical build assessment. No hardware scan is required.
- Scenario-based CPU/GPU tendency
- Memory and frame-rate considerations
- What to benchmark before upgrading
Finish planning your PC.
A strong build also needs appropriate power capacity and realistic running-cost estimates.
Power Supply Calculator
Calculate an initial PSU capacity from component power allowances and safety headroom.
Confirm official GPU minimum PSU guidance before choosing a model.
PC Electricity Cost Calculator
Estimate your monthly PC electricity use in India from wall power, hours and your tariff.
Excludes taxes, fixed charges and slab pricing.
Use estimates. Verify in real games.
Hardware rankings are illustrative and can change across game engines and driver versions. Our PSU tool applies a headroom multiplier to the supplied component power. The electricity tool uses kilowatt-hours × your rate.
Select your scenario
Choose your CPU, GPU, resolution, workload and frame-rate goal.
Interpret the range
See whether the CPU or GPU is likely to be more demanding in that use case.
Cross-check measurements
Look at independent benchmarks, GPU utilization, frame times and cooling before upgrading. Run the measured FPS bottleneck test →
Check performance in your actual games.
Officially sourced testing methods that help you measure performance without invented FPS scores or arbitrary bottleneck percentages.

Can a bottleneck calculator accurately predict FPS loss?
No single percentage applies to all games. CPU/GPU utilization, settings, memory speed, drivers and cooling can substantially change results. Use game-specific benchmarks.
Is high GPU utilization a problem?
Usually not. High utilization is expected in graphics-intensive gaming. Focus on whether the experience meets your FPS and frame-time targets.
How can I check if my CPU is the limit?
Observe frame times, per-thread CPU utilization and GPU usage during your target games. Compare settings and resolution, and review independent hardware benchmarks.
Is the PSU size guaranteed to be enough?
No. Verify manufacturer wattage guidance, peak power spikes, connectors, PSU quality and planned upgrades. This calculator provides an initial sizing estimate only.
Does the Indian electricity result match my actual bill?
The energy arithmetic is precise for the inputs, but utilities may charge fixed fees, tiered rates, taxes or duties. Enter measured average wall power for best estimates.
