It's most likely the PS4's VR unit, which has a processing module made by AMD. Anything 4K would be embedded in their R&D budget, which is paid for mostly by Sony/MS/Nintendo until it goes into production.

Um. No. The box has no GPU in it..  As stated : The PS4 handles all rendering and processing on its own, and the processing unit cannot be accessed by developers.  It does these things:

• powers 3D audio
• enables the social screen (VR gameplay displayed on TV for observers and other players)
• enables a totally separate stream of audio and video to the TV
• displays the PS4 interface and 2D content in Cinematic Mode

Thats it..
