While it's possible to push some processors to speeds faster than their advertised limits - a process called overclocking - eventually a clock will hit its limit and will go no faster.Īs of March 2010, the record for processing power goes to a Cray XT5 computer called Jaguar.
A 3.2 gigahertz processor sends out around 3.2 billion pulses each second. The number refers to how many electrical pulses your CPU sends out each second. When you talk about how many gigahertz your processor has, you're really talking about clock speed. This allows the computer to synchronize all its components and it determines the speed at which the computer can pull data from its memory and perform calculations.
The clock's job is to create a series of electrical pulses at regular intervals. Within your computer's CPU is an electronic clock.
