Explain the Nanometer to me.

post #1 of 10
Thread Starter 
Okay, so I see the term 'NM' in CPUs and GPUs very often now that I'm indulging more into the Hardware industry (first time build on it's way), but, I don't have a clue what it actually means (I realize that smaller is better). Could one of you kind folk please go through this with me. Links are appreciated.

Sorry if this is an extremly silly question, but I'm only young still and I'd rather you guys explain it to me then some random that I found through a Google search.

Essentially it refers to the size of the transistors. The general theory behind it is the smaller the transistor, the more that can be fit on the die (CPU). Correct me if I'm wrong somebody, but the theory also means that the transistors should dissipate less heat, allowing better overclocking potential.

That's the quick version. General convention is smaller is better when it comes to that.

This. Very simple explanation.

@bolded: fixed.

@Red:
Up to a certain point, whereas the size of the transistor gets too small and you can only pump so much voltage through such a small pipe, and Electromigration will kill your chip rather soon-ish.
Imagine throwing a twig in an incinerator.

Just to give you an idea at how small a nanometer is, there are 1 billion nanometers in 1 meter.

Let's just put it this way, Smaller the transistors (or, nanometers of the transistors) = faster clocks, cooler, better overclock potential, marketing factor and 22nm just sounds sexy biggrin.gif

smaller doesnt mean better oc at all ... it only means smaller ...


stop saying it will oc like a god or something ...


the only thing it allows us is have more transistors on the same die space as before .... nothing else ...

the rest is because of the way they make the chip ... the method to implement their design and all ...
