For thoses that do not know, caches (like Wii U's eDram) exist because of the Locality of Reference.
While the unified PS4 memory hierarcy is very simple and consequently easy to use, the funny thing about eDRAM is that a developer can easily write a program to sniff the RAM memory accesses while playing a game so you will be able to know what are the best assets to be promoted from the RAM to the eDRAM.
