Which measur unit process cycle in processor?

Question

i have this question in my exam Process cycle in processor measure by: A) pulse. B)Rate C)cycle D)time Which one is correct! Thank's

Answer 1

The measurement you are probably referring to is Gigahertz (or megahertz. This is the number of times a second the clock changes between a 0 and a 1. Rate, pulse, cycle and time are all equivalent ways of describing this.

You can't accurately compare CPUs using only the clock speed (another common term for frequency) as different CPUs will do a different amount of work in a clock. Also, more CPU cores mean that - for parrellel work loads - more performance.

A quick and dirty comparison can be done by using the CPU benchmark site which boils performance of a CPU down to a number. This gives a relative and raw number to compare processes - bigger is better. How useful this is, however, may depend on your workload.
