More than one number

See the whole system.

A useful PC check considers the processor, graphics card and the supporting hardware around them.

CPU

CPU–GPU balance

Estimate which side is more likely to limit your selected resolution and workload.

RAM

Memory headroom

Check whether your installed RAM fits gaming, creative work or everyday use.

°C

Thermal health

See how your peak temperature affects the overall health estimate.

SSD

Storage experience

Understand where drive speed matters for loading, updates and responsiveness.

PSU

Power headroom

Compare estimated platform demand with the selected PSU capacity.

Upgrade guidance

Turn several checks into a practical next step instead of chasing a single percentage.

Transparent methodology

Understand the estimate.

Our calculator uses relative component tiers and adjusts them for resolution and workload. Supporting hardware is scored separately so one strong component does not hide another limitation.

01

Normalize capability

CPU and GPU choices use relative performance and power values for comparison.

02

Adjust for workload

Gaming, creative work and everyday use put different demands on hardware.

03

Check supporting parts

RAM, storage, temperature and PSU capacity contribute to the health score.

04

Explain the result

The report highlights the limiting scenario and suggests what to verify next.

Common questions.

What is a PC bottleneck?

A bottleneck is a component or condition that limits a particular workload before the rest of the system. The limiting component can change with resolution, settings, frame rate and application.

Is a small bottleneck bad?

No. Every system has a limiting factor in a particular workload. A small imbalance only matters if it prevents you from reaching your intended experience.

Does resolution change a bottleneck?

Yes. Higher resolutions generally increase GPU rendering work, while high-refresh 1080p gaming can put relatively more pressure on the CPU.

How can I verify the result?

Monitor GPU utilization, CPU usage per core, clocks, memory use, temperatures and frame time while running the exact game or application you care about.
