The size and spacing of the processor's transistors (silicon etchings) partially determine the transistor switching speed. The diameter of transistors is measured in microns (µ); one micron is one-millionth of a meter. A human hair is, on average, 30 microns in diameter. Smaller transistors can be packed more tightly in a given area. If they are closer together, there is less distance for the electrical signals to travel, creating a faster processor that runs cooler.
The original Pentium® III processor was based on .25µ and the second version of the Pentium III processor was based on .18µ. The newest version of the Pentium III processor of the Pentium III processor is based on .13µ technology.
The Mobile Pentium® III processor-M are mobile Pentium III processors based on .13µ process technology. They have 133 MHz system bus, 512 KB L2 Advanced Transfer Cache and Enhanced Intel SpeedStep® technology, all which gives maximum performance yet give maximum mobility and battery life. Processors built on Intel's .13µ process technology consume up to 40 percent less power and are up to 20 percent faster than the previous 0.18µ process technology.
Important Note: When using a processor based on .13µ process technology, you must use a laptop computer specifically made to support these processors. Using this processor on the wrong laptop computer will cause the processor to operate out of specification and void the manufacturers warranty.
