Execution Unit

• The main component of the CPU is the execution unit, which is responsible for responding to instructions sent to the CPU from various programs, processes, and hardware components.
  
  

Branch Predictor

• The branch predictor anticipates program actions in order to make data retrieval more rapid for the CPU. The branch predictor also helps improve CPU response time.
  
  

Floating Point Unit

• The floating point unit or numeric coprocessor is the component of the CPU responsible for complicated mathematical calculations. This logic unit performs calculations at a faster rate than the standard logic unit.
  
  

Primary Cache

• Frequently used instructions and locations are stored in the cache. The CPU then uses this cache memory for rapid data retrieval.
  
  

Bus Interface

• The bus interface is the means for connecting the CPU to the Front Side Bus. The FSB is the main connecting mechanism for the motherboard.
  
  

Processor Clock

• The processor clock is the basis for the processor's speed. The clock frequency is measured in MHz or GHz, the equivalent of millions or billions of ticks per second. The clock speed determines how quickly the processor executes its functions.
