WebJan 8, 2013 · Intrinsics Intrinsics are functions which are separately handled by the compiler. These functions are often optimized to perform in the most efficient ways possible and hence run faster than normal implementations. However, since these functions depend on the compiler, it makes it difficult to write portable applications. SIMD WebJul 30, 2024 · Unity recently released Burst 1.5, with a focus on the addition of Arm’s Neon intrinsics. Neon intrinsics let you specify precise vector commands to get the most efficient code possible for processing workloads on Arm CPUs. While they’re normally in C/C++, Unity has brought them through to C#.
