Question: what is the difference between 1ghz and 2ghz?
Answer: One GHz is equal to 1 billion Hz, which is obviously a lot. ... This means that if you have a 1GHz processor, you will get 1 billion operations per second. For 2.16, 2.16 billion and for 3GHz, 3 billion. Now basically, the higher the GHz, the faster the PC, because it can do more things in one core in one second.
