I am not too surprised that they are giving up on the P/E core model. AMD's approach seems much more sane where the "efficiency" cores still have full functionality of the full fat cores.
More intense competition for AMD's X3D line is also a good thing. AMD needs more pressure for price competition and more consumer friendly product management policies.
I am not really all too happy about the switch to Nvidia for graphical acceleration, this sounds like a state sanctioned initiative and it will only serve to reduce the minimal competition we have in the GPU market (Chinese GPUs aren't really viable where I live; I am talking about purely pragmatic reasons, ignoring broader considerations with using Chinese GPUs in this particular case).
