SILICON GRAPHICS UNVEILS REALITY IMMERSION TECHNOLOGY FOR NINTENDO 64 AT
U.S. DEBUT

Silicon Graphics' Digital Media and Visual Computing Technologies and MIPS'
RISC Processors Combine to Deliver First Truly Immersive Video Game
System

LOS ANGELES, Calif. (May 15, 1996) -- Silicon Graphics, Inc. (NYSE: SGI)
and its microprocessor subsidiary, MIPS Technologies, Inc. revealed their
"Reality Immersion Technology" as part of the debut of Nintendo 64 home
video game system at the Electronic Entertainment Expo (E3) in Los
Angeles, Calif. The technology combines Silicon Graphics' powerful digital
media and visual computing technologies with MIPS.' world-leading RISC
processor technology to create the first immersive, highly-realistic home
video game system. Representing a new age of video game entertainment,
Nintendo 64 utilizes a specific custom implementation of this advanced
computer technology to enable players to step inside real-time,
unconstrained, three-dimensional worlds, and become part of the game
itself.

"Silicon Graphics and Nintendo have reinvented video entertainment by
bringing the first truly immersive, interactive experience to home video
game systems," said Tom Jermoluk, president and chief operating officer of
Silicon Graphics. "Nintendo 64 puts Silicon Graphics' powerful visual
computing technology into the hands of everyday consumers. Our plan is to
provide powerful digital media and MIPS RISC processor technology to
consumer companies worldwide, enabling the delivery of a new generation of
affordable, media rich 64-bit consumer electronics products."

"Our partnership with Silicon Graphics has resulted in a gigantic leap
forward for home video games," said Howard Lincoln, chairman of Nintendo
America. "Silicon Graphics has literally taken its high-end visual
computing technology and put it in the hands of consumers in the form of
Nintendo 64. The result is a masterpiece of technology and a new standard
for fun."

At the heart of the Nintendo 64 video game system is Silicon Graphics'
Reality Immersion Technology consisting of a custom version of MIPS 64-bit
R4300i &#1; RISC microprocessor, a MIPS Reality Co-Processor and an
embedded software layer, all optimized for powering a new class of
interactive consumer applications. The Reality Co-Processor, designed
specifically by Silicon Graphics for Nintendo, combines the most advanced
features necessary to create the Nintendo 64 real-time game environment.
They include:

* High frame rate for highly complex images enables unrestrained
interactive movement through virtual 3D space via a combination of a high
fill rate and transform rate;

* Dynamic media mixing allocates the necessary resources for real-time
processing of audio 2D and 3D graphics processing;

* Real-time anti-aliasing removes the jagged edges from objects, creating a
smooth and realistic view as the player moves through a scene;

* Advanced texture mapping techniques generate the industry's highest
quality textures and retain the natural texture of every object in the
scene, independent of how close the player is to an object;

* Real-time Depth Buffering removes hidden surfaces during the real-time
rendering process of a scene, allowing game developers to efficiently
create 3D environments; and

* Automatic Load Management enables the objects in the scene to move
smoothly and realistically, by automatically tuning the graphics
processing.

Nintendo 64 utilizes a special version of the MIPS R4300i microprocessor, a
processor designed by MIPS and manufactured by NEC Corporation using one
of the most advanced commercial semiconductor process technologies in the
world. The powerful R4300i processor is a compact 64-bit RISC processor
with a five-stage pipeline for enhanced media processing. The processor
and Reality Co-Processor together have over 4 million transistors and
combine to produce the made-for-television equivalent of Silicon Graphics'
RealityEngine&#1; graphics technology, the standard for motion picture and
video special effects; scientific, engineering and financial modeling; and
other visualization applications.

MIPS semiconductor capabilities and expertise are key to the scaling and
integration of Silicon Graphics technology to the consumer level. MIPS is
quickly becoming the leader of microprocessor technology for consumer
electronics applications. Last year, MIPS partners shipped over 5.5
million processors, making MIPS the largest computer RISC architecture in
the world. According to reports by Inside the New Computer Industry and
MIPS Technologies, MIPS volume exceeded that of the sum of Power PC,
SPARC, Alpha and Precision Architecture.

Nintendo 64 will be available from Nintendo. Application software will be
supplied by Nintendo and its authorized licensees.
