PassMark PerformanceTest is a benchmarking app for mobile devices that allows users to objectively test the speed and performance of their Android devices. Developed by PassMark Software, the app is available for free and can be used to compare the results of different devices and configurations.

With PassMark PerformanceTest, users can run a variety of speed tests to evaluate their device's CPU, disk, memory, 2D graphics, and 3D graphics performance. The app provides users with objective measurements that can help them make informed purchasing decisions and evaluate the effectiveness of configuration changes and upgrades.

The app's CPU tests include mathematical operations, compression, encryption, and more, while the disk tests measure the speed of reading and writing files to internal and external storage. The memory tests evaluate read and write speeds, and the 2D and 3D graphics tests measure the device's ability to render images and apply filters.
