TDP will restrict any higher releases regardless of the process ability and they are not interested in more volume production quads at 65nm now but 45nm

The FX series was always planned and they have the models for a while now. I do not know what is holding them back apart from competition and the lack of market for it. However, I am not AMD, heck even AMD do not know what will happen as Q3 and Q4 approaches, so you could see higher releases which are not currently known officially. FX82 is already tested since February though, and a Feb 9th update report much after the TLB bug being known mentions more releases: http://www.pcadvisor.co.uk/news/inde...sID=12061&pn=5

Although all those notes are what we knew from Jan, K10 will obviously continue in volume production even while AMD 45nm releases, so you will most likely have higher grades in K10 as you have with K8 65nm G2 now. The report mentions upto 3.4GHz K10 by years end from AMD.

The profit volumes are in the low end/mainstream and the server end, wanting energy efficiency, and that demands an increase in performance efficiency per clock rather than high clocks and high TDPs. If AMD will ever directly compete at 45nm, it will have to be with performance per clock as the main weapon and looking at the cards, that will be an very steep uphill battle.
