"Like what AMD had in late 2009 with the delivery of its first home-grown chipsets – the "Fiorano" SR56X0/SP5100 combo – and the Opteron 4100s in their C32 sockets and the Opteron 6100s in their G34 sockets, which make use of these chipsets, coming out the following spring."
The first AMD home grown chipset is AMD 760 which shipped with Athlon MP and allowed AMD to enter the SMP market. It had one of the most entertaining erratas I have ever seen (at least on MSI motherboards). System was going bonkers if you unplug the PS2 mouse :) That was in 2002 or thereabouts. Nearly 10 years ago.
