A line that stays level
A persistent step down can be consistent with thermal throttling, a power limit, battery saver or competing background work.
Put one or more logical processor threads under a controlled browser load and watch whether throughput holds steady or falls over time.
Choose how much of the processor the browser should keep busy.
Give the run a few seconds before judging it.
A persistent step down can be consistent with thermal throttling, a power limit, battery saver or competing background work.
One thread is a lighter sustained load. All reported threads are more useful for checking cooling response and stability under heavy browser work.
A web page cannot reliably read CPU temperature, clock speed or fan RPM. Use a local hardware monitor if you need those values.
Keep this tab visible while testing. Browsers can throttle background tabs.
A good test should not stop at a score. Use these practical checks to understand what the browser measured, what can affect the result, and what to change before your next call, stream or gaming session.
The test measures work completed by JavaScript under the current browser conditions. It is useful for relative comparisons on the same machine, but browser version, thermal state, power plan and background tasks affect the result.
Performance can fall during a longer run if the processor reaches thermal or power limits. A drop does not automatically mean a defective CPU.
