The PlayStation 4 will feature a single-chip processor (
APU) custom-designed by AMD. It consists of an integrated CPU and GPU. The highly-integrated Sony PlayStation 4 system-on-chip integrates eight AMD x86 Jaguar cores, custom AMD Radeon HD core with unified array of 18 AMD GCN-like compute units (1152 stream processors which collectively generate 1.84TFLOPS of computer power that can freely be applied to graphics, simulation tasks, or some mixture of the two), various special-purpose hardware blocks as well as multi-channel GDDR5 memory controller.
The
central processing unit (CPU) will have eight
x86-64 cores based on the upcoming
Jaguar CPU architecture.
[14] This processor marks a change from the "powerful but difficult to develop for" Cell processor found in the PlayStation 3.
[15]
The
graphics processing unit (GPU) will consist of 18 compute units based on
GCN (Graphics Core Next), resulting in a theoretical peak performance of 1.84
TFLOP/s.
[12]
The GPU will also include dedicated graphics technology for seamless compression and decompression of video media.
The PlayStation 4 will contain 8 GB of GDDR5 unified system memory, allowing for 176 GB/s of bandwidth.
[12][16] The unified memory architecture allows the CPU and GPU to access a consolidated memory, removing the requirement for seperate dedicated CPU and GPU memories.
The read-only optical drive will read
Blu-ray discs at 6x and
DVDs at 8x.
[12] A hard disk drive will be included, although Sony has not yet announced the size.
