Ax Performance Test vs GravityMark GPU Benchmark
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Ax Performance Test
This app measures your device's CPU and GPU performance by dropping cubes until a target frame rate is reached. It calculates a total score based on cube count and polygons rendered per second, displaying detailed performance metrics.
- CPU performance measurement
- GPU performance measurement
- Rigid body physics simulation
- Visible polygons per second display
- Total performance score calculation
- GPU chip leaderboards

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.
GravityMark GPU Benchmark
This app showcases modern GPU power by rendering vast real-time scenes. It offloads all scene management and rendering to the GPU, bypassing CPU bottlenecks. Recommended for devices with Apple A14+ and M1+ SoCs.
- Real-time GPU rendering
- Massive object quantity
- GPU-accelerated scene management
- Bypasses CPU bottlenecks
- Utilizes astronomical data

GravityMark GPU Benchmark demonstrates the capabilities of modern GPUs by rendering an enormous quantity of objects in real-time, utilizing GPU acceleration. We avoid typical CPU-based performance bottlenecks by delegating the entirety of scene management and rendering steps exclusively to the GPU. Apple A14+ and M1+ SoC are recommended for great results. The following resources are used in the benchmark: NASA visible Earth database, GEBCO 2020 grid, the HYG star database archive, ESO / Serge Brunier The Milky Way panorama.
