The Mali-G71 makes the transition to a new architecture, Bifrost (the T880 it replaces and all the way to T6xx used Midgard, used as early as 2012 for the Nexus 10). The G71 focuses on two things - Vulkan and VR. Vulkan is the new graphics API, which aims to provide high performance on both desktops and mobiles. For VR, the new GPU supports the multiview API, essentially a fast, standardized way to render the scene twice - once for each eye. Since the difference in what each eye sees is small, there's plenty of room for...
