Overview
Intel's Pentium® processor combines outstanding performance with the flexibility and compatibility that characterize the personal computer platform. Powering the vast majority of PCs being sold today, the Pentium processor enables a new generation of multimedia and communication-oriented applications. It has immediate responsiveness for the latest software with powerful, realistic graphics and the ability to run full-screen, full-motion video. The Pentium processor extends the range of Intel's microprocessor architecture to new heights, creating an entirely new realm of possibilities for computer systems of today and tomorrow.

The Pentium processor family includes the highest performing members of Intel's family of microprocessors.

Pentium Processor Family Members:

  • Pentium processor at 200 MHz, iCOMP® 2.0 index rating 142
  • Pentium processor at 166 MHz, iCOMP 2.0 index rating 127
  • Pentium processor at 150 MHz, iCOMP 2.0 index rating 114
  • Pentium processor at 133 MHz, iCOMP 2.0 index rating 111
  • Pentium processor at 120 MHz, iCOMP 2.0 index rating 100
  • Pentium processor at 100 MHz, iCOMP 2.0 index rating 90
  • Pentium processor at 75 MHz, iCOMP 2.0 index rating 67
Outstanding Performance for All PC Software
While incorporating new features and improvements made possible by advances in semiconductor technology, the Pentium processor is fully software compatible with previous members of the Intel microprocessor family, thereby preserving the value of users' software investments which are worth billions of dollars. The Pentium processor family meets the demands of computing in a number of areas, for example, the Pentium processor efficiently executes all the leading operating systems and numerous demanding applications such as:

Operating Systems
  • Windows* 95
  • UNIX*
  • Windows-NT
  • OS/2*
  • Solaris*
  • Windows 3.1/3.11
  • NEXTstep*
Compute-Intensive applications
  • Computer-aided design/engineering
  • modeling
  • Large-scale financial analysis
  • High-throughput client/server
  • Network applications
  • Virtual reality
  • Rich electronic mail

The Pentium processor family is produced using advanced semiconductor manufacturing process technology and has features that are less than a micron (one-millionth of a meter) in size. The Pentium processor 75MHz, 90MHz, 100MHz, and 120MHz are implemented in 3.3V, 0.6 micron technology, and the Pentium processor 120MHz, 133MHz, 150MHz, 166MHz, and 200MHz are implemented in 3.3V, 0.35 micron technology.

In addition to containing all the features of previous generations of Intel processors, The Pentium processor family provides significant enhancements and additions including the following:
