Depends on what your definition of excellent yields are... AMD's 28nm yields are better than early 40nm ramp yields which weren't as bad as everybody thinks.
28nm is going very well atm. As long as TSMC keeps increasing capacity like they promised this will be much more smooth than 40nm.

78x0, aka Pitcairn, should be 24CUs on a 256bit bus. Probably around ~3bil trannies and ~240-250mm2.
77x0, aka Cape Verde, should be ~12CUs on a 128bit bus. Probably around ~1.5b trannies and looks like ~130mm2.
