I would expect another AMD architecture using beefed up Jaguar cores, preferable twice the resources available from Jaguar to stay competitive in the higher end of x86 market.
Now I have a question. As Jaguar is now optimized to move around different foundries, how would Jaguar behave if it is optimized specifically for TSMC or Globalfoundries? Would it consume 30% less power while clocked 10-20% higher?
