"stepping" refers to the version or rather the revision number of a CPU.
newer "steppings" are thought to be more stable or faster

Thanks ! :) 

Can you see the stepping somewhere when buying a processor?

I mean on the box...

Yes.

For Intel CPU's, if you look at the Processor Spec Finder and put in what is on the box, like for example Q6600:

BX80562Q6600

or

HH80562PH0568M

You can find the different steppings, as well as the sSpec#, which you can tell that a SL9UM is a B3 stepping, and SLACR is the G0 stepping.

The sSpec# is on the box it came in (retail) IHS as well, which would even be on an OEM CPU.

Not sure about how AMD is, since it's been a long time that I've own one.

Shall we assume what seems obvious, that the name 'stepping' comes from the idea of a 'step', i.e. an incremental movement, from one version to another? Or does it come from something else?
