I'm not so sure. If you listen to the talk he mentions that there will be improvements to the 6300 Opterons. One thing that was never fixed with the PileDriver core was the cache latency. That would not require a mask change. If they could deliver a "Piledriver2" with a modest 10% IPC increase in single thread and a big reduction in power usage (i.e. all desktop models at 95 watt) I would be satisfied enough to upgrade.
If i recall, Piledriver-->Trinity-->Richland. So perhaps fixing the cache and using Richland cores would give them 10% IPC?
Perhaps some ot the more knowledge folks in cpu desingn could enlighten us as to how much could be done without a big mask change.
