3DMark is a free benchmarking app for iPhone and iPad that allows you to test and compare the performance of your device. Developed by Underwriters Laboratories Inc., this app is designed to provide accurate and impartial benchmark results.

One of the main features of 3DMark is the ability to measure the GPU performance of your iPhone and iPad. By rendering a demanding game-like scene in real-time, the app calculates your benchmark score based on how fast the scene runs. You can then compare your score with others who have the same device model, as well as see how your device compares with the latest models.

In addition to benchmarking, 3DMark offers a range of features to help you analyze performance. You can see how your device's performance changes with each iOS update, search, filter, and sort the in-app rankings to compare popular devices, and gain unique insights through charts, lists, and rankings.

3DMark also provides specific benchmarking tests for different scenarios. The 3DMark Solar Bay test allows you to compare the performance of iOS devices that support gaming with real-time ray tracing, a new technology in games that produces more realistic lighting. The 3DMark Wild Life benchmark is a cross-platform app that allows you to compare the performance of the latest smartphones, tablets, and Apple Mac computers with the M1 chip.

Overall, 3DMark is a valuable tool for anyone who wants to assess and understand the performance capabilities of their iPhone and iPad. Download it today and join the millions of users who rely on 3DMark for accurate benchmark results.
