amd chip steppings

This is gonna sound real noob but what exactly are the steppings on amd cpus? what is the difference between them, what inside the chip determines the stepping,and which are the best to use. i understand certain steppings oc better but why? thanx for answers.

CPUs are made in batches, just like cookies. Every batch is given a name, or stepping.

Personaly i think that the later the batch, the better the stepping.
