Motorola, IBM Achieve Breakthrough Performance With New PowerPC 604 Chip
Another design milestone for the alliance

AUSTIN, Texas--April 19, 1994--IBM and Motorola today announced they have
completed development and fabrication of the PowerPC 604 microprocessor,
the most powerful high-volume microprocessor in the industry.

When available in systems, the PowerPC 604 will be the volume
price/performance leader, providing close to twice the performance of
competing microprocessors and providing the power to support new classes
of advanced multimedia, graphics and other applications. The PowerPC 604
is designed to deliver exceptional performance for high-end desktop
systems, mid-range servers and high-performance graphics workstations.

PowerPC microprocessors, jointly designed by Apple, IBM and Motorola, are
based on Reduced Instruction Set Computing (RISC) architecture and
incorporate leading technologies and processes from IBM and Motorola. The
PowerPC 604 at 100 MHz achieved an estimated SPECint92# rating of 160 and
an estimated SPECfp92# rating of 165.

The PowerPC 604 is designed in a 0.5 micron, 3.3 volt Complementary Metal
Oxide Semiconductor (CMOS) technology and incorporates 3.6 million
transistors. It is a superscalar, multiprocessor-enabled chip that issues
up to four instructions in parallel every clock cycle to six execution
units. Its three-stage double precision floating point unit allows end
users to take advantage of increasingly graphics-oriented software
packages, as well as multimedia applications, providing tremendous
performance capabilities that were previously available only through
expensive add-on hardware. The multiple integer units of the PowerPC 604
enable end users to take full advantage of today's and tomorrow's desktop
and server applications.

The PowerPC 604 is the third chip produced on schedule by the alliance,
just 18 months since fabrication of the first chip, the PowerPC 601*.
First silicon for the PowerPC 603 was announced last October. "'The
PowerPC 604 is hands down the most powerful chip in the market," said Phil
Hester, vice president, Systems & Technology, IBM RISC System/6000
Division. "In systems, the PowerPC 604 will give desktop users the kind of
power that not long ago was only available in supercomputers, and will
continue to demonstrate the performance and price/performance advantage
that RISC technology provides over traditional architectures."

Les Crudele, vice president and general manager, Motorola RISC
Microprocessor Division, said, "We believe the compelling performance and
time-to-market advantages of the PowerPC 604 put it far ahead of any other
high-volume microprocessor in the industry."

"The delivery of the PowerPC 604 chip underscores the scalability of the
PowerPC architecture and the platform's great potential," said Steve
Manser, Apple's vice president for desktop computing. "The alliance is
moving ahead to provide low-cost, high-performance technology that will
enable some of the most powerful personal computer systems to date. We
look forward to further extending the price/performance effectiveness of
desktop systems and servers when the chip is available in our systems
starting in 1995."

The PowerPC 604 is expected to begin general sampling in the third quarter
with volume production in the fourth quarter.

Apple Computer and IBM's Power Personal Systems Division plan to introduce
personal computers and servers that use the PowerPC 604 chip, while IBM's
RISC System/6000 Division, Groupe Bull, THOMSON CSF and Harris Computer
Systems plan to introduce workstations and servers. Other companies that
have announced plans for PowerPC chips are Canon, Ford Motor Co., Mercury
Computer Systems, Parsytec, Scientific Atlanta, Tadpole Technologies and
the Taiwan New PC Consortium.

The PowerPC family of microprocessors has the most pervasive software
support of any microprocessor in the industry. Among the operating system
environments supported by PowerPC are Apple's System 7, IBM's AIX and
OS/2, as well as DOS, PowerOpen, Solaris, Taligent, Windows and Windows
NT.

The PowerPC 604 was designed at the Somerset Design Center in Austin,
created through the historic alliance between Apple, IBM and Motorola. The
PowerPC 604 is manufactured by IBM Microelectronics in Burlington, VT, and
Motorola in Austin, TX.

The family of PowerPC microprocessors is designed to address a wide range
of computing requirements, from portable and desktop computers to
mid-range workstations and servers, to multi-processing, fault-tolerant
and supercomputing systems. PowerPC microcontrollers also will be used for
embedded control applications in automotive and consumer products.

Motorola, IBM and third parties also offer comprehensive software,
development tools and support packages for the PowerPC family to enable
hardware and software developers to substantially reduce overall design
time. Many of today's top suppliers of core logic chip sets, graphics
controllers and other system components are also supporting PowerPC
platforms.

Having 1993 worldwide sales of $5.7 billion, Motorola's Semiconductor
Products Sector is the largest U.S.-based broad line supplier of
semiconductors, with a balanced portfolio of more than 50,000 devices.
Motorola is one of the world's leading providers of wireless
communications, semiconductors, and advanced electronic systems and
services. Major equipment businesses include cellular telephone, two-way
radio, paging and data communications, personal communications,
automotive, defense and space electronics and computers. Communication
devices, computers and millions of consumer products are powered by
Motorola semiconductors. Motorola's 1993 sales were $17 billion.
