Traditionally, the way that syntheizing AMD socket information worked is that it required having a table of family, model, stepping and mapping that to a particular revision found in an AMD errata document referred to as a "revision guide". These are sometimes hard to get without NDAs and aren't really necessary for actually knowing what socket something's at. While we can't say this for all older parts, we know that the for newer ones these ranges are more general and therefore we should have a table that can fill in this information even without the other information.
