136 Super Anti-aliasing A feature that improves image quality by combining the results of fullscreen anti-aliasing across two graphics cards in a CrossFire™ configuration. The two graphics cards work on different anti-aliasing patterns within each frame. The results of which are combined by the compositing engine on the CrossFire™ Master graphics card to produce 3D images featuring smoother contours, lines, and shading effects. SuperTiling A graphical load-balancing scheme where two graphics cards are used to render alternate small 32x32 pixel squares in a fine-grained checkerboard pattern. This configuration increases image rendering quality, as each card processes half of the complex 3D objects in the pixel squares. SuperTiling is better optimized for most applications than Scissor Mode (where two graphics cards are used to render the top and bottom halves of the screen), since the checkerboard pattern better ensures a more even distribution of what needs to be rendered. This type of graphical operation is only available in Radeon® CrossFire™ graphics cards running Microsoft® Direct 3D® games or applications. S-Video Short for "Separate Video," S-Video is a type of analog video interface that produces a higher-quality signal compared to composite video. The signal is split into two separate channels- luminance (Y) and chrominance (C). Sometimes referred to as "Y/C video" or "Y/C", the connectors typically contain 4-pins within a single connection housing and are commonly found on consumer DVD players, VCRs, game consoles, and related devices. Texel Short for "texture element," the 3D equivalent of a pixel, describing the base unit of the surface of a 3D object, such as a sphere; for a 2D object, such as a circle, the base unit is a pixel. Texture Mapping In computer graphics, two-dimensional textured surfaces are referred to as texture maps. Texture mapping is the process by which a two-dimensional surface gets wrapped around a three-dimensional object so that the 3D

Super Anti-aliasing
A feature that improves image quality by combining the results of full-
screen anti-aliasing across two graphics cards in a CrossFire™
configuration. The two graphics cards work on different anti-aliasing
patterns within each frame. The results of which are combined by the
compositing engine on the CrossFire™ Master graphics card to produce 3D
images featuring smoother contours, lines, and shading effects.
SuperTiling
A graphical load-balancing scheme where two graphics cards are used to
render alternate small 32x32 pixel squares in a fine-grained checkerboard
pattern. This configuration increases image rendering quality, as each card
processes half of the complex 3D objects in the pixel squares. SuperTiling
is better optimized for most applications than Scissor Mode (where two
graphics cards are used to render the top and bottom halves of the screen),
since the checkerboard pattern better ensures a more even distribution of
what needs to be rendered. This type of graphical operation is only
available in Radeon® CrossFire™ graphics cards running Microsoft®
Direct 3D® games or applications.
S-Video
Short for “Separate Video,” S-Video is a type of analog video interface that
produces a higher-quality signal compared to composite video. The signal
is split into two separate channels— luminance (Y) and chrominance (C).
Sometimes referred to as “Y/C video” or “Y/C”, the connectors typically
contain 4-pins within a single connection housing and are commonly found
on consumer DVD players, VCRs, game consoles, and related devices.
Texel
Short for “texture element,” the 3D equivalent of a pixel, describing the
base unit of the surface of a 3D object, such as a sphere; for a 2D object,
such as a circle, the base unit is a pixel.

In computer graphics, two-dimensional textured surfaces are referred to as
texture maps. Texture mapping is the process by which a two-dimensional
surface gets wrapped around a three-dimensional object so that the 3D
