While powerful, the Vulkan API can be quite complex for mobile developers. At GDC 2019, Arm released a set of Vulkan samples that illustrated a comprehensive list of best practice recommendations. Since then, these have been donated to Khronos Group and have been improved with contributions from other GPU vendors, and the well-known samples from Sascha Willems. The repository contains samples that provide a reference for API features and new Vulkan extensions, as well as performance samples focusing on CPU and GPU optimizations. This blog covers a few of these performance samples, focusing on considerations around limited power and therefore bandwidth on mobile devices with tile-based rendering.
