GHz refers to how many instructions - or cycles - a processor can process per second.
For example, if you has a 2.4 GHz processor, it could do 2,400,000,000 processes per second.
Gigahertz (GHz) = speed
MHz or GHz
CPU speed is measured in megahertz MHz and gigahertz GHz. Your typical processor is going to be in GHz if you have a super computer then it will be in MHz. The CPU speed can be deceiving so make sure you do your research on them.
That would be 1 GHz, though I would not want to attach a CPU of the speed to a bus that fast.
I think it will be in MIPS(Million Instructions Per Second) or Million Floating Point Instructions Per Second.
It means that it contains 2 cores with 2.2 GHz each. For applications that are made to use multiple CPU cores the speed will be as if it was one 4.4 GHz cpu. However, for programs that can't use it it will only be as fas as a single 2.2 GHz CPU, as only one of the cores would be used.
The highest speed i've known that is safe to do to a CPU is 4.0 GHz. And even then that required Overclocking.
GigaHertz (GHz) or MegaHertz (MHz) Gigahertz is much faster
The clock speed at which the CPU can run at, the higher the Ghz the faster it runs, but that means it would need to be cooled down much faster than its current fan speed setting. To increase the Ghz in a computer, this would be referred to as Overclocking.

CPU's are now are rated in Ghz which means "Billions of Cycles per Second" Essentially, the more Ghz the processor has, the faster it will execute instructions. Older computers where rated in mhz which is a million cycles per second. For example, a 2.4 ghz processor is the same as 2400 mhz CPU, or a 500 mhz CPU is the same as a .5 ghz CPU. Single core vs. Dual Core vs. quad core ect, A core is what carries out the instructions. two cores doesn't necessarily mean that the processor will have twice the ghz, but twice the power if the program can take advantage of them.
The gigahertz (GHz) is the largest unit used to represent CPU clock speed. The fastest frequency ever reached was 8.429 GHz, set by the FX-8150 in September of 2011. A more recent claim has been made of 8.805GHz on the same processor, but it has not been officially validated yet.
