enhancement technology. In addition, the Pentium III processor offers Streaming SIMD
Extensions -- 70 new instructions enabling advanced imaging, 3D, streaming audio and video,
and speech recognition applications. The Pentium III processor is supported by
today's most popular operating systems. If you plan to run Windows NT* 4.0 on your
Pentium III processor-based system, you may need a driver from Intel that is specially
designed for these systems. The Pentium III processor delivers the performance for the
next generation of the Internet.
One Powerfully Different Processor
AMD-K6®-III Processor with 3DNow!™ Technology
Superior Processing Power for Home PC Enthusiasts Leading-Edge Performance for Business Power Users
Innovative TriLevel Cache Design - Larger, Faster, More Flexible The Cutting Edge in 3D Computing.
Processor Overview
The AMD-K6®-III processor with 3DNow!™ technology is the ultimate sixth-generation processor
for home PC enthusiasts and business power users. The AMD-K6-III processor combines 3DNow!
technology with AMD's new TriLevel Cache design to deliver exceptional performance on leading
business and consumer software applications. The key to this enhanced performance is our innovative
TriLevel Cache design, which provides the largest total system cache for desktop PCs-more than
four times the size of other competing system designs. Superior Processing Power for Home PC Enthusiasts
In the home and on the Web, the AMD-K6-III takes Windows® 98 to new levels of performance
for a powerful difference in personal computing. Games are faster and more realistic. Multimedia is no
longer a waiting game. And 3D web pages come alive. What's more, a PC powered by the
450-MHz AMD-K6-III processor delivers higher performance on leading consumer applications
than an equally configured PC based on Intel's fastest desktop processor, the Pentium® III 500.
Leading-Edge Performance for Business Power Users
The AMD-K6-III processor outperforms an equally clocked Pentium III and delivers superior
processing power for productivity applications in the Windows NT® environment. Business power
users get all the computational muscle they need to manage web sites, zip through spreadsheets and
word documents, and create high-impact presentations. If there's serious work to be done, PCs
powered by AMD-K6-III processors are right for the job. Innovative TriLevel Cache Design - Larger, Faster, More Flexible
The AMD-K6-III processor's TriLevel Cache design significantly boosts overall PC performance by
providing the largest, fastest, and most flexible total system cache for Windows compatible desktop PCs.
Larger: An AMD-K6-III processor-based PC can deliver up to 2,368KB of total system
cache-more than four times the size of the 544KB maximum system cache of a Pentium III
processor-based PC. In general, the larger the cache, the better the system performance.
Faster: The AMD-K6-III processor's 320KB of internal cache-including a 256KB Level 2
(L2) cache in addition to the 64KB Level 1 (L1) cache that's standard in AMD-K6 family
processors-races along at the full speed of the processor.
More flexible: The AMD-K6-III is the first desktop PC processor to offer a 100-MHz
frontside bus to an optional Level 3 (L3) external cache on the Super7™ platform. This
flexible, three-level cache design results in a maximum combined system cache that's
unsurpassed in the desktop PC industry.

The Cutting Edge in 3D Computing
PCs powered by the AMD-K6-III processor with 3DNow! technology can unleash the potential of
today's gaming, productivity and Internet software for the ultimate 3D multimedia experience.
3DNow! technology can bring PCs to life with sharp 3D images, vibrant graphics, and big-screen
sound and digital video.
Strong Market Momentum for 3DNow!™ Technology
AMD's 3DNow! technology has the support of Microsoft and the independent software and
hardware development community. 3DNow! has been adopted as a 3D enhancement technology by
many of the world's top PC makers, software developers, and game publishers, as well as by an
installed base of more than nine million users who own PCs enhanced with 3DNow! technology.
Some of today's hottest gaming titles are now optimized for 3DNow!, including id Software's Quake
II, Unreal from Epic Games, Rage's Incoming, and Ares Rising from iMagine Studios.
If It's From AMD, It's Compatible.
The AMD-K6-III processor's compatibility is proven through extensive internal and external testing
and verification. The AMD-K6-III processor is compatible with the Microsoft Windows operating
system, other leading operating systems, more than 60,000 software applications, and the latest
software optimized for 3DNow! technology.
