He emphasized the importance of the PS4s GPGPU, stating that it was a “very important feature”.
Cerny explains it best in this quote:
CPU and GPU of a different nature, because it is what it is quite difficult if you now, at this stage, using a unified language based on the architecture, such as HSA, is to increase the efficiency of use. But if you can now use the same language and GPU CPU, the efficiency of the development will increase dramatically. That point will be very big help. I think about these parts, whether it comes to long-term goals so.
Cerny also revealed that the OS is based on BSD, which is a first for consoles:
Seen from the OS side, the PS4, you will be able to use a wide variety of functions simultaneously. Play from the transmission of video game play, then switch to the game as it is now, and even switch to watch a friend’s video game play, as our goal, talking with friends about the video. Go to the store I found something good something, buy in the store, I asked a friend, “Are you OK with this?” … And. It is that feeling like you to use while come and go freely. In multi-player games, without having to “stop” the game, while moving in the background, you can act like this.
