How fast does the CPU work?

With every tick of the clock, the CPU fetches and executes one instruction. The clock speed is measured in cycles per second, and one cycle per second is known as 1 hertz. This means that a CPU with a clock speed of 2 gigahertz (GHz) can carry out two thousand million (or two billion) cycles per second.

What does a better CPU improve?

Installing the faster CPU also increased transfer speeds on the hard drive, most likely because the drive was also being used as the operating system volume, and background tasks that would interrupt the drive benchmark were minimized with the faster processor.
