PS4 architect discusses console's custom AMD processor
 

Since February, we've known that Sony's upcoming PlayStation 4 console will have a "supercharged PC architecture" based on a custom AMD processor with GCN-derived graphics and eight Jaguar CPU cores. The chip's GPU and CPU elements will share 8GB of GDDR5 memory over an interface with a claimed 176GB/s of bandwidth, and the graphics component promises comparable horsepower to the Radeon HD 7850. Gamasutra recently discussed the PS4's underlying hardware with lead architect Mark Cerny, providing new insight on the guts of the console.
