## What is Ax Performance Test?

Simple non-deterministic cube performance test.

Measures CPU and GPU performance. Drops cubes until the frame rate averages less than 60. Cubes stack and tumble following rigid body physics properties.

CPU performance is measured via physics performance and GPU is measured via the number of cubes your device can render.

Displays visible polygons per second.

A total score is calculated based on the number of cubes times the polygons per second.

Leaderboards for each individual GPU chip.

## Key features

- CPU performance measurement
- GPU performance measurement
- Rigid body physics simulation
- Visible polygons per second display
- Total performance score calculation
- GPU chip leaderboards


## Frequently asked questions about Ax Performance Test

### What is Ax Performance Test?

Ax Performance Test is a utility app designed to measure your device's CPU and GPU capabilities. It uses a non-deterministic cube dropping simulation to assess performance.

### How does Ax Performance Test measure CPU performance?

CPU performance is measured through the physics simulation of the tumbling cubes. The app tracks how efficiently the processor handles these physics calculations.
