M22/M24 (MOBILITY RADEON X300/X600): SMARTSHADER™ 2.0

>

M26/M28 (MOBILITY RADEON X700/X800): SMARTSHADER™ HD

Feature Description: >

>

Shaders are the key technology that allow game developers to program a limitless range of more sophisticated effects in games that execute on the graphics processor.

ATI Advantage: >

SMARTSHADER™ technology supports and accelerates the latest game effects, allowing gamers to see immersive, life-like worlds with an unparalleled level of realism

SMARTSHADER™ 2.0 Examples

DirectX7.0 effects (no shader support)

SMARTSHADER supports DirectX9.0 which enables effects such as the night sky, light glow, and shadows

SMARTSHADER™ 2.0 Examples

The same scene using DX8.0 effects only cannot properly render the water effects as intended by the game

SMARTSHADER support for DX9.0 allows for realistic water effects. In this scene the images of the rocks under the water are effected by the ripples of the water , the reflection of the wall and the glare of the light

SMARTSHADER™ 2.0 Demos

>

This demo makes the best use of the powerful and flexible vertex/fragment shaders of ATI SMARTSHADER to achieve dynamic simulation of fur motion along with glossy fur shading

>

Matrix skinning allows for decent animation of simple, bidirectional joints such as knees and elbows

>

Bump mapping relies on light-reflection calculations to create small bumps on the surface of the object in order to give it texture CONFIDENTIAL :: ATI

SMOOTHVISION™ Technology >

ATI Product Support: M22/M24 (MOBILITY RADEON X300/X600): SMOOTHVISION™ 2.1 > M26/M28 (MOBILITY RADEON X700/X800): SMOOTHVISION™ HD >

>

Feature Description: Provides better 3D image quality through features like Anti-Aliasing (AA) and Anisotropic Filtering (AF) techniques. > Anti-aliasing enhances image quality by smoothing jagged edges on object outlines. > Anisotropic filtering improves image quality by sharpening blurry textures to bring out finer detail. >

>

ATI Advantage: >

ATI SMOOTHVISION™ is a set of technologies designed to enhance the image quality of any game using advanced, high-performance filtering technology even at high resolutions in the latest games without performance degradation.

SMOOTHVISION™ Examples: Far Cry

Without Anti-Aliasing many “jagged” lines are present in a typical 3D scene

SMOOTHVISION supports advanced multi-sampling for up to 6 samples per pixel for “smoother” effect

SMOOTHVISION™ Examples: Far Cry

1x Anisotropic Filtering

Improved Anisotropic filtering for greater detail and better image quality

8x Anisotropic Filtering

M22/M24 (MOBILITY RADEON X300/X600): VIDEOSHADER™

>

M26/M28 (MOBILITY RADEON X700/X800): VIDEOSHADER™ HD

Feature Description: >

>

A key feature of the video processing engine that allows it to tap into the power of the programmable pixel shader units of ATI’s graphics solutions

ATI Advantage: >

Allows shaders to be used to accelerate many different video processing tasks, de-blocking (FULLSTREAM™), adaptive de-interlacing, frame rate conversion, color space conversion, and much more. These features greatly improve image quality without any negative performance effects.

VIDEOSHADER™ Demo: FULLSTREAM™

FULLSTREAM technology dramatically changes the quality of internet streaming video

13

VIDEOSHADER™ Demo: Adaptive De-Interlacing “WEAVE” de-interlacing uses lines from the previous or next field to fill in the missing lines.

“BOB de-interlacing fills in the missing lines by interpolating from the lines that are present in the current field. This works well when there is motion

Adaptive per-pixel de-interlacing selects the best blending algorithm (Bob and Weave) on a per-pixel basis.

3Dc™ Technology >

ATI Product Support: >

>

Feature Description: >

>

M26/M28 (MOBILITY RADEON X700/X800) new compression technology designed to bring out fine details in games while minimizing memory usage.

ATI Advantage: >

Exclusive ATI feature that allows for up to 4:1 compression, meaning game designers can now include up to 4x the detail without changing the amount of graphics memory required and without impacting performance to the end-user, resulting in more realistic scenes and characters during gameplay.

PCI Express Demo: “Pinnacle” Video Editing >

Pinnacle Systems is a developer of advanced digital video editing software >

>

The goal for the next generation of video editing applications is real time editing of HD content. >

>

software supports compositing of real-time 3D effects with multiple video streams from a variety of sources

“Real time” is typically considered to be 30-60 fps

AGP does not have enough upstream bandwidth to support HD video transfers, > >

the CPU is forced to do all of the work and then pass the final output downstream across the AGP bus for display. the CPU must simultaneously decompress, edit, blend, and compress multiple video streams.

>

Frame rate drops well below real-time levels on an AGP-based system

>

PCI Express system can handle simultaneous HD video streams and maintain interactive frame rates of over 30 frames per second. CONFIDENTIAL :: ATI
