Superscalar Execution

There are multiple internal instruction execution pipelines are included in fifth-generation Pentium and newer processors, allowing them to execute multiple instructions at the same time. The 486, like all previous CPUs, can only execute one instruction at a time. The capacity to execute multiple instructions at once is referred to as superscalar technology by Intel.

The superscalar architecture was originally connected with high-output RISC devices. The instruction set of a RISC processor is less complex, having fewer and simpler commands. Despite the fact that each instruction achieves less, the entire clock speed may be increased, which improves performance. The Pentium was one of the earliest superscalar complex instruction set computer (CISC) processors. A CISC chip has a more complex instruction set and employs a richer, more feature-rich instruction set. Let's imagine you wanted to teach a robot how to change a light bulb. You would express the following using CISC instructions:

  1. Pick up the bulb.
  2. Insert it into the socket. 
  3. Rotate clockwise until tight.

You'd say something more along the lines of the following if you used RISC instructions:

  1. Lower hand.
  2. Grasp bulb.
  3. Raise hand. 
  4. Insert the bulb into the socket.
  5. Rotate clockwise one turn.
  6. Is the bulb tight? If not, repeat step 5

Because each instruction is simpler (reduced) and performs less, many more RISC instructions are required to complete the task. The advantage is that the robot (or processor) has fewer overall directives to deal with, and it can execute individual commands more quickly, and therefore finish the task (or program) more quickly in many situations. The question of whether RISC or CISC is significantly better continues to be debated, although there is no such thing as a pure RISC or CISC chip—all it's a matter of definition, and the lines are fairly arbitrary.

Although the fifth- and later-generation versions contain multiple RISC qualities and internally break down CISC instructions into RISC versions, Intel and comparable processors have been recognized as CISC chips.
