The "Test Performance CPU GPU" app loads the CPU with a maximum number of threads on your device and measures performance. You choose how many cores should be loaded. Additionally, a unique function allows for separately loading the graphics core from the processor. If the phone can handle the cooling, the performance will remain consistent over time, however, if it can't, the CPU will slow down, resulting in decreased speed.

This app provides a graphical representation of performance and measures maximum, minimum, and average performance. It also notifies you of any throttling that may occur. Considering that performance degradation depending on the number of loaded cores is normal, monitoring how performance changes over time is important.

The application displays two independent graphs of processor and video core performance. You can lock loads for either of them at your discretion. Additionally, you can adjust the graph display parameters and measurement accuracy to suit your needs.

This app can be used as a mobile performance benchmark to measure differences between CPUs of certain phones, for example, when two phones use the same chipset but are from different manufacturers. By conducting this test, you can determine if there are cooling differences between phones, thus identifying which one throttles the most. Moreover, you can compare your results with real-world data from other phones and tablets using the system performance metrics for comprehensive performance analysis.
