Oooohh! CPU has a components! Their are 3 . First is the Control units , it control all parts of computer system.Second is the Arithmetic logic unit, it performs logical operations and the last, the Registers, its just a temporarily stores the most frequently used instructions and data.

And about the control units, it manage for basic operations ,cool isnt?. Its a machine cycle Hahaha! Control units have two cycles, one is the Instruction cycle,in this it has two . The fetch and the Decode. Fetch gets the program instruction from the memory f computer Nd Decode ,figures out, what the prog is telling to do from computer. The second control unit is the execution cycle, in this we have an execute that performs the requested actions ,and the arithmetic Logic Unit (ALU) that performs a basic logic and arithmetic operations like adding,subtrating, dividing and multiplying also it compares alphanumeric data. 

For the Microprocessor Performance, it has three kinds : Data bus width, Word size , system clock and operation cycle. First lets talk about Data bus width, so they measured in bits ,isnt?  It is the number of path ways within the CPU that transfer data. Second is Word size, the CPU can process at one time ,and it is the maximum data.Third is system clock,it is the electronic circuit who generates pulses at rapid rate and it synchronizes the computers internal activities. And the last a operation cycle, also called clockspeed, so it is the number of clock cycles per second measured in megahertz or gigahertz. In Operation cycle it has two: the Superscalar operation and Pipelining operation
