What does this test measure?
CPU-GPU balance score based on hardware specifications and typical workload profiles.
Why is this test important?
Find out if your CPU or GPU is limiting your PC performance in games and applications.
How do you run the test?
Click Start Test, enter your CPU and GPU models, and view the bottleneck analysis.
How should results be interpreted?
A large imbalance means one component is significantly holding back the other.
Normal and problematic results
A large imbalance means one component is significantly holding back the other.
Technical limitations
Bottleneck depends on resolution, game engine, and specific workload; results are estimates.
Why can the score decrease?
Unstable measurements, denied permissions, unsupported browser APIs, background load, power saving, or an incomplete test can affect the result. When a score changes, the result screen explains the reason.
What should you do if a problem is found?
Upgrade the bottlenecking component, or match CPU and GPU tiers more closely.

Frequently Asked Questions
Does this test provide a definitive hardware diagnosis?
No. The test measures signals the browser can safely access and clearly explains its technical limits.
Why can results change between runs?
Background applications, power mode, network conditions, permissions, and operating-system timing can affect results.
How should I repeat the test if I see a problem?
Repeat it on the same device and browser while changing only one condition, so the source of the difference is easier to identify.
