Why is processor speed important?

Processor speed is important because it determines how fast or slow the computer runs. The processor is the brain of the computer. It handles all the numerical calculations; therefore, if the calculation time is slow, the entire system's its overall performance gets affected.

Processor speed is measured in how many cycles it can perform in a given second. Therefore a high processor speed means that more instructions per second will be executed. Processor speed is important especially when performing graphics-intensive tasks such as video editing and gaming.

A high speed processor is able to run powerful programs without draining the system’s resources or shortening its lifespan.
