Netbook Processors and Graphics

I was looking at netbooks and am curious what the difference between the Atom N and Z series processor and what is the difference between Intel Integrated GMA 945/950 and 500?

Is one processor faster or better than the other? How about the graphics chipsets?
 
Both of the intel gpu's are as slow as James May. You should look for a atom 330 with ION. That'll be up to 4x times faster.
