INTEL BEGINS SHIPPING ITS FIFTH-GENERATION PROCESSOR
Pentium(TM) Microprocessor Delivers
112 Million Instructions Per Second
SANTA CLARA, Calif., March 22, 1993 -- Intel
Corporation, the world's largest semiconductor
company, today began shipping its fifth-generation
processor -- the Pentium(TM) processor. The Pentium
chip continues the company's record of providing top
performance processors that maintain 100 percent
compatibility with over $50 billion worth of installed
software used throughout the world.
Intel microprocessors serve as the "brains" for
over 70 percent of the world's 100 million installed
personal computers. The Pentium processor performs
112 million instructions per second (MIPS) making it
five times more powerful than the original
Intel486(TM) microprocessor (today's most popular PC
microprocessor), or over 300 times faster than the
8088, the brain of the original IBM PC. The chip
contains 3.1 million transistors, compared with 1.2
million transistors for the Intel486 chip.
The Pentium processor will provide increased
computing power for users of high-end applications
such as high-volume client/server applications,
complex financial analysis, computer-aided design and
engineering programs. The increased computing power
of the Pentium processor will also make a host of new
applications such as full-motion video, voice
recognition and imaging on personal computers a
reality.
"The Pentium processor represents a new
generation of power for the Intel architecture. The
Pentium processor will enable the best
price/performance systems in the marketplace," said
Albert Yu, senior vice president and co-general
manager of the Microprocessor Products Group.
"The Pentium processor will run all the current
software without modification and with a substantial
performance improvement," added Paul Otellini, senior
vice president and co-general manager of Intel's
Microprocessor Products Group. "Using new high-
performance tools and compilers that have been
developed in concert with software vendors, new, even
greater levels of performance will be possible as
software developers optimize their products to run on
the Pentium processor."
Intel will ship hundreds-of-thousands of Pentium
microprocessors in 1993. "Pentium processor volume
will pass the million mark in 1994 and we would expect
the Pentium chip to be the 'processor of choice' for
personal computers in the mid-nineties," said
Otellini.
New Technology
The Pentium processor is manufactured using
Intel's 0.8 micron, three-metal layer BiCMOS process
technology. The chip is available in 66 and 60-MHz
speeds. The Pentium chip's design features
superscalar technology, two five-stage execution units
that allow it to process two instructions
simultaneously, two 8K on-chip caches (high-speed
memory), and a fully compatible floating point unit
that is up to five times faster than an Intel486 DX
chip at the same clock speed.
The Pentium chip also incorporates a number of
additional advanced design techniques that can
dramatically improve application software performance.
One such technique is called "branch prediction" where
the chip remembers prior instruction pathways and
predicts the correct pathway for a new instruction to
follow.
Upgradability
Many of today's personal computers that use
Intel486 DX2 microprocessors will be upgradable to
Pentium processor technology in the future. An
OverDrive(TM) Processor, based on Pentium processor
technology, will be available in 1994 allowing PC
users to increase their systems performance without
having to replace their computer.
Name Change
In naming the fifth-generation of its compatible
microprocessor line the Pentium processor, Intel
departed from tradition. It breaks a string of CPU
(central processing unit) products from Intel dating
back to the late 1970s that used numerics (8086, 286,
386, 486). Pentium uses the Greek work for five
"pente", as its root to associate with the fifth-
generation of compatible microprocessors from Intel,
and uses "ium" a common ending from the periodic table
of elements. Thus the Pentium microprocessor is the
fifth-generation, a key element for future computing.
Intel, the world's largest chip maker, is an
international manufacturer of microcomputer
components, modules and systems.
