Title: Intel Microprocessors

Intel Microprocessors
  • A Short History

1971 4004 Microprocessor
  • The 4004 was Intel's first microprocessor.
  • This breakthrough invention powered the Busicom
    calculator and paved the way for embedding
    intelligence in inanimate objects as well as the
    personal computer.

1972 8008 Microprocessor
  • The 8008 was twice as powerful as the 4004.
  • According to the magazine Radio Electronics, Don
    Lancaster, a dedicated computer hobbyist, used
    the 8008 to create a predecessor to the first
    personal computer, a device Radio Electronics
    dubbed a "TV typewriter." It was used as a dumb

1974 8080 Microprocessor
  • The 8080 became the brains of the first personal
    computer--the Altair, allegedly named for a
    destination of the Starship Enterprise from the
    Star Trek television show.
  • Computer hobbyists could purchase a kit for the
    Altair for 395.
  • Within months, it sold tens of thousands,
    creating the first PC back orders in history.

1978 8086-8088 Microprocessor
  • The sale of the 8088 to IBM's new personal
    computer division made it the brains of IBM's
    new hit product--the IBM PC.
  • The 8088's success propelled Intel into the ranks
    of the Fortune 500, and Fortune magazine named
    the company one of the "Business Triumphs of the

1982 286 Microprocessor
  • The 286, also known as the 80286, was the first
    Intel processor that could run all the software
    written for its predecessor.
  • This software compatibility remains a hallmark of
    Intel's family of microprocessors.
  • Within 6 years of it release, there were an
    estimated 15 million 286-based personal computers
    installed around the world.

1985 Intel 386(TM) Microprocessor
  • The Intel 386TM microprocessor featured 275,000
    transistors--more than 100times as many as the
    original 4004.
  • It was a 32-bit chip and was "multi tasking,"
    meaning it could run multiple programs at the
    same time.

1989 Intel 486(TM) DX CPU
  • The 486TM generation really allowed the shift
    from command-level computing into point-and-click
  • The Intel 486TM processor was the first to offer
    a built-in math coprocessor, which speeds up
    computing because it offers complex math
    functions from the central processor.

1993 Pentium Processor
  • The Pentium processor allowed computers to more
    easily incorporate "real world" data such as
    speech, sound, handwriting and photographic
  • The name Pentium, mentioned in the comics and on
    television talk shows, became a household word
    soon after introduction.

1995 Pentium Pro Processor
  • Released in the fall of 1995 the Pentium Pro
    processor is designed to fuel 32-bit server and
    workstation-level applications, enabling fast
    computer-aided design, mechanical engineering and
    scientific computation.
  • Each Pentium Pro processor is packaged together
    with a second speed-enhancing cache memory chip.
  • The powerful Pentium Pro processor boasts 5.5
    million transistors.

1997 Pentium II Processor
  • The 7.5 million-transistor Pentium II processor
    incorporates Intel MMXTM technology, which is
    designed specifically to process video, audio and
    graphics data efficiently.
  • It is packaged along with a high-speed cache
    memory chip in an innovative Single Edge Contact
    (S.E.C.) cartridge that connects to a motherboard
    via a single edge connector, as opposed to
    multiple pins.
  • With this chip, PC users can capture, edit and
    share digital photos with friends and family via
    the Internet edit and add text, music or
    between-scene transitions to home movies and,
    with a video phone, send video over standard
    phone lines and the Internet.

Where to from here?
Moore's Law
  • Gordon Moore once observed that the speed and
    power of microprocessors seems to double every 12
    to 18 months. This trend has held true for the
    past 20 years and is showing no sign of slowing
  • What does this mean for the future of computing?
    What other technologies can you think of which
    get faster and more powerful every year, and yet
    also get cheaper and more affordable!
