Write out stage generated bounding volumes

Systems, apparatuses and methods may provide for technology that optimizes tiled rendering for workloads in a graphics pipeline including tessellation and use of a geometry shader. More particularly, systems, apparatuses and methods may provide a way to generate, by a write out fixed-function stage, one or more bounding volumes based on geometry data, as inputs to one or more stages of the graphics pipeline. The systems, apparatuses and methods may compute multiple bounding volumes in parallel, and improve the gamer experience, and enable photorealistic renderings at full speed, (e.g., such as human skin and facial expressions) that render three-dimensional (3D) action more realistically.
