The Playstation 4 doesn’t have the horsepower to maintain VR performance due to its outdated hardware; therefore, the console has to leverage power from a separate source called a Processing Unit, which Sony calls PU, which splits the video signals and supplements a large power boost.
“We call it a PU, and it’s a box that takes the output from the PlayStation 4 and it splits it, splits it for something for the headset and something for the television… And it does this conversion of the 120Hz output of a PS4 that something a TV can display, and it doesn’t get warped. That let’s the people in the room that are there to see what you’re seeing.”
The PS VR will ship in 2016 with a library consisting of 10 games. The Price will be more than the console itself.
