INTRODUCTION

Pentium is a certain series of processors from Intel. It is a development of (and thus compatible with) older microprocessors from Intel such as 8088, 8086, 80286, 80386 and 80486. Computers built around these processors are usually called PC-compatible. Pentium works on the x86 architecture.

There are other manufacturers of processors with the same instruction set, such as AMD with its K5 and K6 processors. Computers with such processors could at that time be considered as PC-compatible.

PROCESSORS

PENTIUM 
The first Pentium processor was launched in March 1993. It had a design fault which meant that the floating-point calculations could give quite a mysterious rash. There was also a bug that made an instruction to lock the processor until the computer was restarted. Pentium was Intel's first processor that had several pipelines; it had two pipelines which were five steps long each.

PENTIUM PRO 
Pentium Pro was introduced in November 1995. Its core (P6) was the direct foundation for the Pentium II and Pentium III and significant similarities are also seen with Pentium M, Core and Core 2, but with major revisions, particularly to the latter.

PENTIUM II 
Intel's successor to the Pentium Pro had the project name Klamath. When it went on sale in May 1997 it was named Pentium II. There were some changes to the Pro model.

A new feature from Intel was their decision to put the processor in a PC card with a Single Edge Contact-design (SEC), which fitted in the Slot 1 connector on the motherboard for Pentium II. Previously you could choose between a CPU from...
