Sony has revealed in some length but not with pix, the currently available specifications for its PS4, the all new console revealed last evening (GMT) in NYC.
"The PS4 system architecture is distinguished by its high performance and ease of development. PS4 is centered around a powerful custom chip that contains eight x86-64 cores and a state of the art graphics processor", it begins a bit stuffily but then it hots up some.
"The Graphics Processing Unit (GPU) has been enhanced in a number of ways, principally to allow for easier use of the GPU for general purpose computing (GPGPU) such as physics simulation. The GPU contains a unified array of 18 compute units, which collectively generate 1.84 Teraflops of processing power that can freely be applied to graphics, simulation tasks, or some mixture of the two."
