What is the Difference between Athlons with AGOIA and AGOGA cores?

Anyone care to shed the light on this for me? I'm puzzled

agoia is a newer and much better stepping than agoga. alot better overclocking potential.

agoia overclocks better, i think agoga cores only got amd to xp2000+, agoia were able to take them the extra mhz for 2100+
