Eight core AMD x86 processor with Radeon graphics drive the console
Updated with statement on used game support Despite little mention of solid tech specs at the reveal, Sony has released a list of technical specifications for the upcoming console. Confirming earlier rumors, the PlayStation 4 runs AMD multi-core silicon, with a "next generation" Radeon graphics processor rated at 1.84 teraflops in the die of the CPU.
In full, the spec sheet includes a single-chip custom processor with eight x86-64 AMD Jaguar CPU cores with integral Radeon graphics processor, 8GB of GDDR5 memory for both system operations and graphic utilization, a built-in hard drive, a 6x Blu-Ray drive capable of 8x DVD speeds, USB 3.0 and other auxiliary ports, Gigabit Ethernet, 802.11 b/g/n Wi-Fi, and Bluetooth 2.1. Audio/visual outputs are a single HDMI port, analog AV-out, and an optical S/PDIF audio output.
Mandatory to the console is the PlayStation 4 Eye camera, with a pair of 1280x800 cameras with fixed focus lenses and an 85-degree field of view. The Dualshock 4 controller mounts a two-point capacitive touchpad, three-axis gyroscope and accelerometer, light bar with three-color LEDs, a speaker, a micro-USB port, a stereo headset port, an unspecified extension port, and a 1000mAh battery for wireless operation.
The x86 nature of the computer should simplify cross-platform development for whatever the next-generation Xbox holds, and PC gaming. While the Jaguar processor was present at CES, it is not a high-speed chip, and AMD aims the line at laptops and tablets. An eight-core processor, implemented properly, should still deliver an order of magnitude greater power than the current Core processor in the PlayStation 3 and minimize heat by keeping clock speeds down.
Update:While a previous patent suggested that Sony may be investing in technology to block the use of used games on its new console, an interview with Sony Worldwide Studios executive Shuhei Yoshida by Eurogamer confirmed the device's ability to play used titles. When directly questioned by the interviewer regarding the used titles, and after consultation with a PR staffer, the executive said that "So, used games can play on PS4. How is that?" Additionally, a Sony staffer told the same interviewer that the Sony patent had nothing to do with the PlayStation 4.
