Z-fighting
Demonstration of z-fighting with multiple colors and textures over a grey background Z-fighting, also called stitching, is a phenomenon in 3D rendering that occurs when two or more primitives have similar or identical values in the z-buffer.

128-bit
While there are currently no mainstream general-purpose processors built to operate on 128-bit integers or addresses, a number of processors do have specialized ways to operate on 128-bit chunks of data.
