The PlayStation 4 spec list has been refreshed thanks to Orbis documentation and the development kit.
Kotaku has acquired a list of specs for the unannounced PlayStation 4 "Orbis" console that are based on the development kits, model # DVKT-KS000K, as of January 2013. It's noted that these specs will likely change as the console gets closer to its final retail date, so take these components as merely what's provided for developers for the moment. AMD will take the center stage, providing both the CPU and GPU.
According to the specs, the kit has 8 GB of RAM and 2.2 GB of video memory. The CPU is listed as 4x dual-core AMD64 "Bulldozer" – indicating that there will be eight cores total – and the GPU is listed as an AMD R10xx. Also included is a 160 GB HDD, a Blu-ray drive, four USB 3.0 ports, two Ethernet ports, HDMI and optical output, and 2.0, 5.1 and 7.1 audio channels.
Kotaku added that there's also a headphone jack but it's unclear whether this will end up on the final product. It's also noted that the extra Ethernet port will likely not end up in the final build, as it's used for local sharing and testing purposes.
Kotaku goes on to cover the controller aspect, saying that developers are working with both the Sixaxis and DualShock 3 controller, indicating that the design and capabilities will be similar to the PlayStation 3 models. There's also a new model in development called the Orbis Development Tool which retains the same features but adds one key component: a capacitive touch pad as seen with the PlayStation Vita. It will recognize two-point multi-touch input, and will also serve as an additional input button when "clicked".
The PlayStation 4 will also supposedly offer multi-user simultaneous logins, meaning the console will allow more than one person to be logged into the same system at the same time. This is done by linking controllers to user accounts, thus when a second player activates a controller, he/she will be asked to log into their account. This would indicate that all user information will be stored in the cloud including trophies and game settings which can be accessed on any PlayStation 4 console.
Kotaku said the information contained in its report was generated from the development kit, and from official Orbis documentation provided by the same individual who attempted to sell a pair of Xbox development kits on eBay last year.
