Playstation 4 specifications

As new PS announced for this year, we all want to know it's specs, don't we? 

PS vs. Xbox - who's going to win?









These are not official specifications yet, these are prototypes, some changes may be made!

RAM Memory: 8GB (DDR3)
Graphics card: AMD R10xx - 2.2GB
CPU (Processor):  4x Dual-Core AMD64 "Bulldozer" (8 cores)
HDD: 160GB
Optic-drive: Blu-Ray
Ports: 4x USB 3.0 & 2x Ethernet 
Audio ports: HDMI & Optical 2.0, 5.1, 7.1 channels 

One more interesting thing, as Kotaku said, PS4 controller should have touch-pad, which should be on back side of controller, code name - "Orbis Development Tool". This controller should be optional, with new console should come slightly changed PS3 controller.
