The PlayStation 4 uses a semi-custom accelerated processing unit (APU) developed by AMD in cooperation with Sony and is manufactured by TSMC on a 28 nm process node. Its APU is a single-chip that combines a central processing unit (CPU) and graphics processing unit (GPU), as well as other components such as a memory controller and video decoder/encoder. The console also includes secondary custom chips that handle tasks associated with downloading, uploading, and social gameplay. These tasks can be handled seamlessly in the background during gameplay or while the system is in sleep mode.

Though not much is publicly known of the PS4’s audio capabilities, the console also contains a dedicated hardware audio module, which can support in-game chat with minimal external resources as well as “a very large number” of MP3 streams for use in in-game audio.
