• This has to do with processor speed. A basic rule is the more GHz, the faster a computer is. Newer chips will always have more GHz than older ones. When computers were new, GHz was out of the question - MHz was fast...
  • GHz comes from GigaHertz which is just a level up from MegaHertz (MHz), GigaHz = 1000MHz MHz = 1000Hz
  • Ghz = Giga Hertz. The term "hertz", is a measurment of freuqency created by Heinrich Rudolf Hertz. 1 hertz is equal to 1 a second. In computer processors, hertz are used in showing the amount of processes occuring for every second. In theory a computer with a 2.6Ghz processor, is capable of making 26000000000 procceses a second, but due to different types of cpu architecture, it is more like 22000000000 procceses. These procceses are also measured in IPS (Instructions Per Second). Which make a 2.6Ghz Proccesor capable of 22000000000 IPS or more commonly 22000 MIPS. The more procceses a computer is able to perform a second, the faster the computer will be. But a computers speed is determined by more than just CPU speeds, buts thats another question.
  • when buying a computer is 320 MB hard drive and 1024 MB ram larger than 1200MHz and 384MB ram
  • GHz - Gigahertz - 1 billion hertz, its basically 1 billion cycles per second which is used to measure CPU. cpu is measured in cycles per sec.
  • GHz (gigahertz) refers to the clock speed of the CPU (central processor unit), and may also refer to the speed of built-in devices such as a GPU (graphic processing unit) or working memory (RAM), but the latter is often referred to in MHz.
