Pentium III
Story
​
The Pentium III owes its appearance to the ongoing war between Intel and its biggest competitor, AMD.
This manufacturer had launched its processors with 3DNow instructions, which made it excellent for using 3D instruction sets.
Given this advance from AMD, Intel had to get going and released its Pentium III.
Actually, this processor was nothing more than a Pentium II, to which specific orders had been added for the handling of 3D, making it equal to its competitor from AMD. These new orders received the name of KNI (Katmai New Instructions) and also incorporated an improvement of the MMX orders, called MMX-2.
The Pentium III was manufactured in two formats, in a vertical format called "Slot 1" and in a vertical format called "socket 370" and with bus speeds of 100 MHz and 133 MHz.
