"Tile-Based Rendering is a special method of rendering images on the screen
which reduces overdraw and increases the "effective" fill rate. The KYRO
works differently than most accelerators. Most 3D accelerators draw and shade
polygons in a scene, regardless of whether you can actually see them or not.
This causes many, many polygons to be drawn which are not actually seen,
wasting processing time and resources. The KYRO eliminates this by rendering
the scene in "tiles" - it breaks up the onscreen image into several pieces
and examines each individually. Before all the polygons are drawn and shaded,
the KYRO examines whether or not they will be displayed on screen - if not,
them in doesn't render them and consequently drastically reduces the power it
needs to display 3D scenes. This is the KYRO's form of Hidden Surface
Removal, or HSR."
