The power of the CPU established the fundamental power of the computer and its model number establishes the basic model number of the computer.
Some computers also contain a chip called a co-processor.
The co-processor handles mathematical computations and frees up the CPU to do other tasks. Computers with a co-processor are significantly more powerful than those without them. Finally, all computers have an internal crystal clock that governs the CPU's speed. The Processor Chip - Each time a more powerful CPU comes out, it is called a new generation of CPU and it is given a model number higher than its predecessor. Well, the company that makes these chips was sued in a claim that they could not copyright a string of numbers like 486.
