Is it the more GHz the better?

Clock speed is the rate at which a processor executes a task and is measured in Gigahertz (GHz). Once, a higher number meant a faster processor, but advances in technology have made the processor chip more efficient so now they do more with less.

Regarding this, which is better GHz or MHz?

The "at least" is because multiple operations often occur in one clock cycle. Both megahertz (MHz) and gigahertz (GHz) are used to measure CPU speed. For example, a 1.6 GHz computer processes data internally (calculates, compares, copies) twice as fast as an 800 MHz machine.
