      ATI TECHNOLOGIES ANNOUNCES 3D RAGE - VALUE-PRICED CHIP TO ENABLE
              ARCADE-EQUIVALENT GAMING ON MULTIMEDIA HOME PCs
---------------------------------------------------------------------------

NOVEMBER 13, 1995 - Las Vegas, Nev. - ATI Technologies Inc. (TSE:ATY) today
announced 3D RAGE, the first 3D chip that meets the price/performance
milestones set by manufacturers of the next generation of Multimedia Home
PCs and provides a comprehensive 3D arcade-caliber tool kit for games
developers to create visually stunning games on the PC.

Value-priced, and featuring dizzying arcade-caliber gaming on the PC, 3D
RAGE is the most integrated high performance multimedia accelerator in its
class. 3D RAGE marries rich 3D features with all of the capabilities of its
award winning mach64 2D accelerators, adds full-screen, full-motion 30
frames per second (fps) MPEG video playback and enhanced support for all
major consumer video applications to produce the most intense gaming
experience available on a PC. The new chip also utilizes the latest SGRAM
memory providing four times the performance of current DRAM products at
DRAM comparable pricing. Next generation synchronous memories keep
bandwidth-hungry video and 3D engines found in advanced multimedia
accelerators running smoothly.

"With 3D RAGE, ATI completes the PC gaming puzzle," said Henry Quan, ATI's
vice president of marketing. "Capitalizing on proven technologies and
stable, open platforms, we have brought together the best of 3D, 2D and
video, all in one product, which will not only produce the most powerful
experience for the hard core gamer but will provide the ultimate, maximized
tool for games developers."

"After years of anticipation, everything will finally be in place over the
next 12 months to foster a leap forward for the PC viewing experience,"
said Mike Feibus, Analyst with Mercury Research. "This is due primarily to
the confluence of three factors. First and foremost is Windows 95, with
open and available APIs. Second is the emergence of accelerators like ATI's
3D RAGE that provide support for 3D and video as well as two-dimensional
graphics. And third, the developing hardware-software platform is spurring
games developers to make use of the technology. It will be an exciting
year."

"Companies like Microsoft and ATI are leading the industry to transform the
PC into the ultimate gaming platform," said Kate Seekings, Microsoft's 3D
Evangelist. "With the introduction of 3D RAGE, ATI has once again shown
that they understand the needs of games developers and systems
manufacturers and have built in all the features and performance these two
parties need to capitalize on this huge business opportunity."

Built for Current and Future Needs

Priced at $48 (in quantities of l0,000), with samples available now and
full production to begin in first quarter 1996, 3D RAGE is the first chip
of its kind which will enable systems manufacturers to provide completely
integrated, high performance 2D/3D/video for arcade-caliber gaming in an
easily upgradeable multimedia system which could sell for less than $2,000.
The second in its accelerator family to incorporate ATI's recently
announced Enhanced Visual Architecture (EVA), 3D RAGE allows OEMs to design
a single low-cost multimedia motherboard which incorporates the critical
features the new multimedia consumer is demanding such as TV-tuner,
hardware MPEG and video conferencing.

The PC - An Inherently Superior Gaming Machine

With industry experts predicting sales volumes of "next generation"
multimedia PCs at over 10 million units in l996, the revenue potential for
PC games is far greater than that of "next generation" games consoles. As
well as providing the virtual reality experience of 3D, the PC as a gaming
platform supports TV-quality video, interactivity for tele-gaming and
LAN-based multi-player gaming, making it an inherently superior gaming
environment, virtually unmatchable in the console market. Games developers
need a predictable, stable, high performance platform to ensure that PC
games can be created that will be a significant improvement over the
console experience. ATI's 3D RAGE has been built to meet these criteria and
with an installed base of over l0 million accelerators, ATI is a proven
volume supplier of multimedia hardware and can deliver the customers for
games publishers to support the development of 3D games on the PC.

Rather than catering to a proprietary, closed environment like some other
multimedia accelerator vendors, ATI's 3D RAGE leverages off the strong
industry standards being developed by companies like Microsoft. It supports
all major Application Programming Interfaces (API) including Microsoft's
Windows 95 Direct3D and Reality Lab, Apple's TinselTown and QuickDraw 3D,
Argonaut's BRender and Criterion's RenderWare. Coupled with the latest
gaming add-ons such as joysticks, 3D input devices, Virtual Reality
headsets and Digital Simultaneous Voice Data (DSVD) modems used for
tele-gaming, 3D RAGE will enable totally new gaming categories.

The Ideal Development Tool

"While other graphics and video vendors continue to launch 'trade-off
technology', ATI's 3D RAGE supports all major APIs, accelerates all six
Direct 3D texturing modes and incorporates all the features a games
developer needs to optimize the gaming experience," said Craig Fryar from
the OEM division of game publisher Interplay Productions. "Put this amazing
product together with ATI's reputation for shipping quality multimedia
hardware in volume and games developers have a winner."

With performance rates of over 20 million perspectively correct texture
mapped pixels per second and 575K+ Gouraud shaded triangles per second, 3D
RAGE has the best single chip performance currently available in this
category. To achieve comparable functionality and performance, other
vendors require the use of multiple chips like triangle set-up engines and
DACs, which adds to total system costs. Also, many chip manufacturers
provide limited features forcing the game developer to compromise image
quality in favor of speed, or vice versa. ATI allows the games developers'
creativity to reign supreme by allowing them to decide how they want to use
3D RAGE features to create the ultimate experience depending on the class
of game they are developing.

By utilizing PCI bus mastering, 3D RAGE further increases system
performance. For example, texture maps can be swapped at high speeds
between system and graphics memory which offloads the CPU to perform tasks
such as calculating triangle vertices, resulting in significantly higher
frame rates, which provides a dramatically enhanced gaming experience.

3D Rage supports perspectively-corrected bi- and tri-linear filtered
texture mapping for the highest level of virtual reality immersion. In
addition, support for all six Direct 3D modes in conjunction with sub-pixel
accuracy creates an amazing gaming experience. It also supports 3D Gouraud
shaded polygons to accelerate the rendering of solid color surfaces. Hidden
surface removal using Z-buffering is also available so the developer can
decide whether to use graphics memory to offload the CPU from having to
perform the taxing Z-sort algorithm when building 3D images.

Ardent gamers are truly addicted to eye-popping 3D which games developers
achieve using special effects, such as alpha blending, fog and texture
lighting, which have all been incorporated into 3D RAGE. With the video
texturing feature of 3D RAGE, developers can render live video images
direct from an MPEG source onto 3D surfaces for state-of-the-art visual
effects.

The Ultimate Video Accelerator

3D RAGE provides the highest possible video functionality including support
for all major consumer video applications. MPEG playback functionality
provides broadcast-quality, full screen, full motion, true color video. To
transform your PC into an intelligent TV that harnesses all of the
entertainment capabilities of a TV with the processing power of a PC, a
TV-tuner capability can be added on so users can channel surf, do instant
replays, capture their own TV transcripts and more. An optional hardware
MPEG upgrade will provide the highest quality video images at full screen,
30 fps speeds guaranteed, completely removing the task of processing video
from the CPU. Enabling all of this multimedia expansion is ATI's EVA
architecture with its built-in ATI Media Connector (AMC) which allows for
the efficient transport of video and audio between multimedia devices and
cards.

ATI is the first to include both front-end and back-end video hardware
scaling to handle two or more video streams simultaneously, a key
requirement for the burgeoning modem-based video conferencing market. PCI
bus mastering offloads the CPU from bi-directional transfer of video
between the system memory and the accelerator.

3D RAGE - The Ideal OEM Product

ATI clearly has an advantage over the several new entrants who have
appeared in the 3D acceleration market. OEMs are building Home PCs for
users who are not only demanding great 3D, 2D and video acceleration, but
who also want proven feature rich drivers and utilities. In addition, OEM
system manufacturers are selling into a multiple niche market where
TV-tuners, hardware MPEG and videoconferencing are in high demand. 3D RAGE
provides all of this functionality plus ensures pin compatibility with
current and future mach64 multimedia accelerators and options provides
local language support to lessen the cost for the OEM to sell the product
in international markets.
