More than 600 Hardware and Software Products Optimized for AMD Technology and Platforms

Expanding List of AMD-Optimized Products Demonstrates Widespread Industry Commitment to AMD Athlon™ Processor Platform, 3Dnow™ Technology

SUNNYVALE, CA -- 10/4/1999 -- AMD today announced that more than 600 hardware and software products have been optimized to support its processor platforms and 3DNow!™ technology. The industry's top hardware and software developers continue to announce new entertainment and business productivity titles, graphics drivers, audio cards, DVD applications, utilities, 3D engines and development tools optimized for use on AMD-powered platforms.

"The substantial developer commitment to AMD's technologies and platforms demonstrates AMD's ability to generate the support required to successfully bring to market a differentiated PC platform," said Ned Finkle, director of AMD's Infrastructure Technology Development Group. "Expanding developer support will become increasingly important as AMD continues to deliver next-generation technologies and platforms that enable a superior computing experience."

More than 20 million PCs worldwide include AMD processors with 3DNow! technology, and that number is projected to expand to 25 million by the end of 1999. 3DNow! technology is available in the complete range of desktop PCs, from leading-edge systems featuring the AMD Athlon processor, to performance PCs powered by the AMD-K6®-2 or AMD-K6-III processors.

Software Support
Since the inception of 3DNow! technology in May 1998, many of the foremost entertainment software publishers and business productivity software companies have announced support for the SIMD (Single Instruction Multiple Data) technology targeted at accelerating the floating point calculations that enable an enhanced multimedia PC experience. Leading business productivity software developers including Microsoft, IBM, Dragon Systems, Lernout & Hauspie, Viewpoint, Caligari and Geometrix are also working with AMD on infrastructure technology development programs. Software publishers and developers including 3DO, Accolade, Activision, Digital Anvil, Electronic Arts, Eidos, Fox Interactive, GT Interactive, Gremlin, id Software, Infogrammes, Interplay, Psygnosis, Rage, UbiSoft and Sierra all offer multiple software titles optimized for 3DNow! technology that provide an enhanced experience when used in conjunction with AMD processors.

Hardware Support
Industry leading 3D graphic accelerator suppliers, including 3Dfx, ATI, Matrox, NVIDIA, S3, 3Dlabs and Trident are shipping 3D graphics accelerator drivers optimized for 3DNow! technology. Graphics board manufacturers supporting 3DNow! technology include Creative Labs, Guillemot, Diamond Multimedia and Videologic.

About the AMD Athlon™ processor
The AMD Athlon processor is an x86-compatible, seventh-generation design featuring a superpipelined, nine-issue superscalar microarchitecture optimized for high clock frequency; the industry's first fully pipelined, superscalar floating point unit for x86 platforms; high-performance cache technology, including 128 KB of on-chip level-one(L1) cache and a programmable, high-performance backside L2 cache interface; enhanced 3DNow!™ technology with 24 new instructions designed to improve integer math calculations, data movement for Internet streaming, and DSP communications; and the AMD Athlon system bus ­ a 200MHz system interface based on the Alpha™ EV6 bus protocol with support for scalable multiprocessing.

The AMD Athlon processors are manufactured on AMD's 0.25-micron process technology in FAB 25 in Austin, Texas.

The AMD Athlon processor's seventh-generation microarchitecture, superscalar floating point engine, and high-bandwidth, 200MHz system bus enable it to achieve performance levels never before attained in an x86 processor. The AMD Athlon processor significantly outperforms previous-generation processors, such as Intel's Pentium® III product family, and delivers the highest floating point, integer, and 3D multimedia performance for x86 system platforms.

About 3DNow!™ Technology
AMD pioneered 3D and multimedia instruction extensions with its introduction of 3DNow! technology in May 1998. To accompany the introduction of the 650MHz AMD Athlon processor in August 1999, AMD unveiled an enhanced version of 3DNow! technology, designed to take 3D multimedia performance to new heights. The enhanced 3DNow! technology includes AMD's original 21 3DNow! processor instructions, as well as 24 new instructions. The superscalar SIMD (Single Instruction Multiple Data) instruction set significantly boosts the processor's ability to handle floating-point calculations, providing for lifelike visuals, theatre-quality sound and a richer Web experience. In enhancing 3DNow! technology, AMD kept the instruction set design simple yet powerful, allowing developers to adopt the technology and optimize their applications quickly, and enabling easy implementation for software developers. 3DNow! technology has received numerous industry awards, including "Most Innovative Technology of the Year for 1998," awarded by Maximum PC, and "Technical Innovation Award for 1998," awarded by PC Magazine.
