After fumbling around in the dark making my own attempts at processor annotations (Which to be fair I think are OK if a bit messy :D), I discovered someone known as Nemez, who does extremely detailed and professional looking die annotations. This person goes into great detail and if you are interested in a (very) educated guess of the blocks of some of these chips check out their work on their website and also twitter:
I can't believe I only just found this person. I'm very excited to see their annotation of the 'Raven2' silicon die featured in Athlon 3000G, which I also just got my hands on :3.
Such a baby little chip. :3
