GeForce3 Product Overview
The NVIDIA® GeForce3™ Graphics
Processing Unit (GPU) shakes up the
gaming industry with unprecedented
visual effects and sizzling frame rates—
injecting life into the previously artificial
world of computer-generated graphics.
Powered by the new NVIDIA nfiniteFX™
Engine and the Lightspeed Memory
Architecture™, the GeForce3 GPU enables
users to look into a rich environment
instead of just a computer screen. 3D
scenes have ambiance with GeForce3
because textures appear photo realistic
and custom lighting heightens the drama.
Characters and living creatures have
organic imperfections and unique
expressions—you can see their personality.
Programmability and performance have
been combined to provide the catalyst for
this graphics revolution
The GeForce3 GPU's nfiniteFX Engine gives
developers the ability to program a
virtually infinite number of special effects
and custom looks. Instead of every
developer choosing from the same hardcoded palette of effects and ending up
with the same generic look and feel,
developers can specify personalized
combinations of graphics operations and
create their own custom effects. Games
and other graphics-intensive applications
offer more exciting and stylized visual
effects. Two patented architectural
advancements enable the nfiniteFX
Engine's programmability and its multitude
of effects: Vertex Shaders and Pixel
Vertex Shaders inject personality into
characters and environments. Motion
invades the entire scene, not just the focal
points. The vertex processing capabilities
allow characters to move and show facial
emotion, materials to stretch, and the
scene to come alive. By customizing the
skinning and motion effects, developers
can create a personality, intensifying the
impact of the visualization or animation.
Pixel Shaders create ambiance with
materials and surfaces that mimic reality.
A virtually infinite number of material
effects replace the artificial, computerized
look with high-impact organic surfaces.
Characters now have facial hair and
blemishes, golf balls have dimples, a red
chair gains a subtle leather look, and
wood exhibits texture and grain. By
altering the lighting and surface effects,
artists are able to manipulate colors,
textures, or shapes to generate complex,
realistic scenes.
The Lightspeed Memory Architecture brings
power to the GeForce3, delivering earthshattering performance and fluid motion
for even the most complex scenes.
NVIDIA's patented technology delivers AA
samles at nearly four times the rate of the
GeForce2 Ultra™, enabling highresolution
antialiasing (HRAA) with fluid frame rates.
The GeForce3 delivers more than 800
billion operations per second (BOPS)—more
than twice the raw performance available
to consumers in today's GPUs. For more
complex scenes and visuals, the GeForce3
advantage grows to as much as a sevenfold increase in delivered performance.
Combine the personality and ambiance
enabled by the nfiniteFX Engine and the
power of the Lightspeed Memory
Architecture, and the results are superior
visual effects and game play. No other
graphics processor provides as much
functionality. That's why the NVIDIA
GeForce3 is the reference platform of
choice for the Microsoft® DirectX® 8
application programing interface (API) and
the technology foundation for the
Microsoft next-generation Xbox™ game
console. GeForce3 delivers the most
visually compelling and the most complete
graphics experience available today.
