    1. Rage Fury MAXX™

    2. Rage Fury MAXX™ The Answer to today’s 3D dilemma High performanceAND High quality AND Universal application acceleration

    3. 3D Tradeoff The classic hardware trade-off Speed (Frame Rates) vs. Quality (Resolution, Color Depth, Texture Size) vs. Scene Complexity (Triangle Count) Software community lag Creates user confusion and frustration

    4. Why High Resolution Gaming? • Increased realism • Flight sims, FPS’s, sports • High resolution eliminates jaggies and need for anti-aliasing • Improved playability • Strategy games • View larger fields in greater detail • Flight sims, FPS, sports • Able to see finer detail and respond earlier • Increased Satisfaction • Enjoy better “eye candy”

    5. Traditional Solutions • 3D pipe parallelism • Faster engine clocks • Higher memory bandwidth • More of the 3D Pipe - e.g. T&L Each of these options have advantages and limitations

    6. 3D Pipe Parallelism • Setup engine • More triangles per second • Rendering engine • Multiple pipes, single pass multi-texturing • More rendered pixels per second • Both result in larger dies • Implications • Decreased yield due to larger die • Increased complexity lowers clock speeds • Process technology limits cost effective die size

    7. Faster Engine Clocks • Design for 150+ MHz increases engine throughput (triangles and pixels) • Decreased yield at speed • Limits ASIC complexity • Process technology limits cost effective engine speeds • Simpler architectures are easier to push

    8. Higher Memory Bandwidth • Design for higher speed memories increases rendering bandwidth • 166MHz or faster SDR SDRAM or DDR SDRAM • Enables high frame rates at high resolutions • Implications • More costly memory • More exotic memories not in mass production • Lower ASIC yield (as for higher engine clocks)

    9. More Pipeline - T&L • Offload CPU with Transform and Lighting acceleration on ASIC • Increases scene complexity through higher supportable triangle count • Implications • Larger die - lower yield • Higher complexity - lower speed in a given technology (.18 micron is where it becomes viable) • Must wait 8-12 months for software to take advantage of this

    10. The ideal gaming solution would • Support higher resolutions and color depths for games over the next 12 months with • A balanced approach to • Clock speeds (memory and engine) • ASIC size • Parallelism • Transparent software support • .25 micron technology for high quality, high volume production

    11. The solution... ATI MAXX™ (Multiple ASIC) Technology

    12. Mass Market Multiple Chip Processing Techniques 3Dfx’s Scan Line Interleave (SLI) Metabyte/Wicked 3D Parallel Graphics Configuration (PGC) ATI’s MAXX™ (Multiple ASIC) Technology

    13. Issues Required specific chip design No AGP support Sychronization delays ASIC’s cannot work ahead (inefficient design) No DAC calibration Scan Line Interleave (SLI)

    14. Issues Bus imbalance (PCI vs. AGP) Imbalanced load Scene complexity in top half typically lower than bottom ASIC’s cannot work ahead Image tearing No DAC calibration Parallel Graphics Configuration (PGC) - Split Frame Rendering

    15. Software Community Lag • Software community lags hardware • API support and game engine develop lags • Optimizations unique to each chip • Reduces ISV development and support cost • User unable to realize full acceleration capabilities (eg. geometry) • User and channel confusion with 3D software support

    16. AURORA Project Goals • Develop a patentable technology that demonstrates ATI’s technology and performance leadership • Using multiple (2) current ATI ASICS • on a single AGP board • With transparent support for OpenGL and D3D applications • Architecture that supports future ATI ASICS

    17. “Difficult” Problems • “Bridgeless” Design • Driver transparency • Frame/texture/rendering management • Page flip synchronization • DAC calibration • Efficient use of each ASIC Desire for a simple, quality design that could be leveraged with future ASIC’s

    19. ATI Multiple ASIC Technology Patent Pending Engine rendering load is cut in half Engine rendering capacity is doubled Each engine renders alternate frames

    20. MAXX™ Performance • Alternates frame rendering between ASICs for a very efficient use of resources - each frame does half the work • Render ahead if required -- engines do not have to wait for each other as is the case with SLI and split frame techniques • Can be fully decoupled for single ASIC software and OS compatibility

    21. Performance Con’t • High fill rate, 500 Mpixels/sec • Superior memory bandwidth: 4GB/sec • Run full speed in 32bpp hi-res modes with large 64 MB (dual 32MB configuration) • Performance achieved with standard, readily available production parts

    22. 3D Community Lag RAGE FURY MAXX™ accelerates all D3D and OGL applications • No changes needed to games • Accelerates past, current and future generations of applications • ATI drivers split rendering and display activity without software invention

    23. Target Market • High-end gamer who is passionate about: • Frame rate (speed, power) • Game optimization • Frame buffer size • Benchmarks • Resolution • Maximum visual stimulation • Latest games

    24. Rage 128 Pro Advantages • Rage Fury MAXX™ operates like a Rage Fury Pro in 2D mode • Stable, high volume quality • Superior 2D performance • Leadership Video features and quality • Integrated HW DVD

    25. Key Selling Features • FASTEST Game Frame Rates Today • Multiple ASIC technology and true colour rendering performance for ultimate speed • High Resolution, True Color Display • 64MB memory • for photo realistic game play with massive textures • ATI MAXX™ Technology

    26. Rage Fury MAXX™ Strengths 32 bit true color for highest quality Multitexturing requires 32bpp in order to avoid color banding or flat washed out colors Highly realistic blending and lighting effects Quality without a compromise in frame rates High fill rates (> 500 megapixels/sec.) required for rendering at true color, 1280x1024 and 1600x1200 resolution Ideal for high resolutions and high color depth

    27. Limitations • Performance benefits reduced below 1024x768 resolution compared to single ASIC solutions • 64MB is configured as two 32MB frame buffers • 2nd ASIC does not assist 2D performance

    28. ATI Rage Fury MAXX™ vs. GeFORCE256 The MAXX™ advantage: • Faster performance especially in 32bit mode • More memory for the same price as opposed to less memory with T&L. Games require higher fill rates in high resolution and not much from geometry.

    29. The Future • More driver performance enhancements • Possible higher clock speeds • Future ASICs on MAXX™ platform ATI MAXX™ Technology will continually provide the leading edge gamer with the best game experience
