RASTERIZER
! There are 4 Geometry Processors on Radeon™ Radeon™ R9 290x
‒ Overall Primitive Rate = 4 prims per clock (ideal)
! There are 4 Rasterizers on Radeon™ R9 290x (4 triangles x 16 pixels = 64 pixels per clock)
‒ Each rasterizer can read in a single triangle per cycle, and write out up-to 16 pixels
! Caveat: tiny (e.g. sub-pixel) triangles can dramatically reduce PS efficiency
! This can cause us to become raster-bound, unable to rasterize at peak-rate!

13. Tiled Resources & Partially Resident Textures
! Enables application to manage more texture data than can physically fit in a fixed footprint
‒ Known as: Tiled Resources (Direct3D 11.2) and Partially Resident Textures (OpenGL 4.2)
‒ A.k.a. “Virtual texturing“ and “Sparse texturing”
! The principle behind PRT is that not all texture contents are likely to be needed at any given time
‒ Current render view may only require selected portions of a texture to be resident in memory
‒ Or, only selected MIPMap levels…
! PRT textures only have a portion of their data mapped into GPU-accessible memory at a time
‒ Texture data can be streamed in on-demand
‒ Texture sizes up-to 32TB (16k x 16k x 8k x 128-bit)
