Improving gaming performance by default on the billion-plus Arm-powered mobile devices is at the foundation of the Arm and Unity partnership. The joint work on the Burst Compiler on Android is set to enhance multicore processor performance and power management to further improve the quality and longevity of mobile game play sessions.

In this session, Arm and Unity will share how the addition of Arm Neon hardware intrinsics, the incredible SIMD technology, to Burst 1.5 allows developers to further improve their performance by targeting specific hardware instructions available on Arm platforms directly from C#.


Attendees will learn when to use Neon intrinsics with Burst compiler and how to do it in a most efficient way in their Unity games when targeting Arm’s architecture. They will also get an insight into optimizing performance and battery usage when using SIMD on mobile devices.

Intended Audience

This session is accessible for game developers creating mobile games in Unity, particularly those interested in CPU performance and optimizations.
