innovative and substantive



    "High fidelity refers
to a superb reproduction, which is completely true to the original," said Matrox
president, Lorne Trottier. "The engineering vision fulfilled by Matrox
Parhelia-512 was to achieve the highest-fidelity graphics with the truest
representation of colour, 3D, text and images created by a single source of
incomparable quality, performance and features."


    Unparalleled Visual

    To achieve the
highest-fidelity graphics, Parhelia-512 has been designed with tremendous
attention to detail paid to every aspect of the graphics pipeline. Parhelia-512
continues Matrox's unwavering focus on raising the bar in cutting-edge visual
quality by bringing significant new quality-based innovations to market. This
leading image quality and support for the latest display technologies are key
attributes of the product. Some specific quality-related innovations include:


            •  10-bit
GigaColor Technology - Parhelia-512 delivers the PC industry's first true 10-bit
per colour channel support for the simultaneous                      display of
over one billion colors. Full 10-bit precision per colour channel is maintained
throughout the pixel processing pipeline, inside                      the frame
buffers, as well as in the RAMDACs and TV encoder  for  additional  precision
in  2D,  3D, DVD  and  video.  10-bit GigaColor is                a
forward-looking technology, which provides an exceptionally vibrant Microsoft®
Windows® desktop, the richest graphics, as well            as the sharpest 3D
images and in-game graphics.


            •  UltraSharp
Display Output Technology - The display output subsystem of Parhelia-512 is
based on a sophisticated new design                              that delivers
truly high fidelity RGB, DVI and TV output. Parhelia-512's dual 400Mhz RAMDACs
are fully  gamma  correctable  to  10-bit                         per channel
accuracy. Both RAMDACs and the integrated TV encoder, output signals with 10-bit
per channel signal quality. This                           technology combined
with the most highly developed electronics and filters, delivers the
highest-quality analogue, digital and TV outputs—Matrox's best ever. 


            •  64 Super
Sample Texture Filtering - Parhelia-512 integrates the world's most advanced
texture filtering units allowing for the dynamic                      
allocation of up to 64 texture samples per clock—double the number available on
competing GPUs. These samples can be flexibly allocated to provide higher
quality texture filtering with minimal performance impact. For example, the 64
samples could be arranged                                             to deliver
dual textured pixels with trilinear filtering, instead of bilinear filtering, at
no performance penalty; or dual textured pixels with                         
        16-sample anisotropic filtering at comparable performance to trilinear
filtering on competing GPUs.


            •  Glyph
Antialiasing - Parhelia-512 is the first graphics technology to provide hardware
accelerated antialiased text and font rendering                       with full
gamma correction—a feature currently available in Microsoft operating systems
but only accelerated in software.                                       
Furthermore, Glyph Antialiasing takes the operating system's  text  quality 
initiative  one step  further by  offering  programmable                  
           gamma correction for the antialiasing of text. Glyph Antialiasing
makes onscreen text more readable and provides the ultimate

desktop viewing experience without compromising performance.


            •  16x Fragment
Antialiasing (FAA-16x) ­ This revolutionary approach to antialiasing delivers
the highest quality antialiased rendering                           with minimal
performance impact. For applications compatible with FAA-16x, Parhelia-512
intelligently antialiases only pixels on triangle                    edges and
applies a full 16 times super-sampling to those pixels while leaving interior
pixels sharp and unblurred. As edge pixels                             typically
make up only a small fraction of the pixels in the scene, Parhelia-512 is able
to offer this superior quality with a very small performance penalty.


    Superior Performance


With massive
memory bandwidth and a colossal array of 3D processing elements, Parhelia-512
delivers the fastest 2D, Microsoft DirectX® 8, OpenGL 1.3 and DVD performance.
It sustains very high levels of performance even during the rendering of complex
3D scenes with high polygon counts, FAA-16x antialiasing, 8-sample anisotropic
filtering, 10-bit GigaColor Technology and deep vertex and pixel shaders.
Parhelia-512 pushes the limits of design and architecture by integrating the
following high fidelity performance technologies:


            •  512-bit GPU - Parhelia-512 is the first 512-bit GPU and the first
device with a true 256-bit wide DDR local memory interface, which can         
        provide over 20 GB/s of raw memory bandwidth. Forming the backbone of
the rendering and display engine, the 512-bit architecture              
           and massive memory bandwidth enable Parhelia-512 to sustain the
highest performance for the most complex 3D and 2D applications, even during
high resolution, multi-display computing.


            •  Quad DirectX 9 Vertex Shader Array - Parhelia-512 integrates four
Microsoft DirectX 9 compatible vertex shader units into a single              
           vertex processing array. Powered by a sophisticated control unit,
with deep instruction and register caches, Parhelia-512 is able to             
        sustain very high performance levels even when executing  complex 
vertex  shader  programs  on  high-resolution  3D  models.   In addition,  
            Parhelia-512 is optimised for OpenGL standard lighting models and
handles these at accelerated rates.


            •  Quad
Texturing - Parhelia-512 is the first GPU to enable single-pass quad texturing
with four pixel-per-clock throughput. With the latest                   
generation of 3D games, and a plethora of future games expected to push the
limits of texturing beyond dual texturing, Parhelia-512                      is
the only GPU that provides a rendering platform that sustains performance for
cutting-edge graphics applications.


            •  36-Stage
Shader Array - With four programmable texture- and five programmable pixel-shader
stages on each of its four pixel                              pipelines,
Parhelia-512's 36-Stage Shader Array boasts the largest and most powerful pixel
rendering pipeline to date. The massive                            shading power
of the engine allows Parhelia-512 to render the most demanding next-generation
content at high performance levels.



    Distinct Innovative


With a
steadfast tradition of bringing trend-setting new features to market, Matrox
leads the way once again with Parhelia-512, which offers the following
substantive and innovative features: 


            •  Hardware
Displacement Mapping (HDM) - Hardware Displacement Mapping is a powerful new
method of representing and rendering                       complex 3D geometry
using a simple data representation. Matrox is the first to develop a hardware
implementation of displacement                           mapping and has
contributed elements of this technology for inclusion as a standard feature in
Microsoft’s DirectX 9 API.  Hardware                        Displacement mapping
works by encoding high-resolution geometric detail into 'displacement maps',
which represent height                   displacements from a low-resolution
object mesh and stores this data in simple texture maps. Using dynamic,
depth-adaptive vertex                         tessellation and mip-mapped vertex
texture sampling, Parhelia-512 recombines the base mesh with the displacement
map in real time to                       enable stunningly realistic 3D
rendered scenes.
