AMD Zone had an interview with AMD, here's a snip:
We just recently announced that in March of 2006 we began first revenue shipments of 90nm AMD64 chips out of Fab 36. AMD ramped Fab 36 to 90nm volume production in record time, by the way, extending our track record of flawless manufacturing execution. I'm happy to say, our plans for 65nm as well as 45nm are on-track as well. We expect that 65nm wafer starts will account for more than 50% of total production at Fab 36 by early 2007, and we expect substantial conversion to 65nm by mid-2007. We are on track for 45nm production in Fab 36 by mid 2008.
