The PlayStation 4 uses an Accelerated Processing Unit (APU) developed by AMD in cooperation with Sony. It combines a central processing unit (CPU) and graphics processing unit (GPU), as well as other components such as a memory controller and video decoder. The CPU consists of two quad-core Jaguar modules totaling 8 x86-64cores. The GPU consists of 18 compute units to produce a theoretical peak performance of 1.84 TFLOPS. The system's GDDR5 memory is capable of running at a maximum clock frequency of 2.75 GHz (5500 MT/s) and has a maximum memory bandwidth of 176 GB/s. The console contains 8 GB of GDDR5 memory, 16 times the amount of RAM found in the PS3 and is expected to give the console considerable longevity. It 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. The console also contains an audio module, which can support in-game chat as well as "a very large number" of audio streams for use in-game. All PlayStation 4 models support high dynamic range (HDR) color profiles.
Its read-only optical drive is capable of reading Blu-ray Discs at speeds of up to three times that of its predecessor. The console features a hardware on-the-fly decompression module boosting optical disc reading speed and buffer unread data when a game is not actively accessing the optical drive. The original PS4 model can output in 4K and play multimedia in the format, but does not play games in 4K. The console includes a 500 gigabyte hard drive for additional storage, which can be upgraded by the user. System Software 4.50, which was released on March 9, 2017, enabled the use of external USB hard drives up to 8 TB for additional storage.
The PlayStation 4 features Wi-Fi and Ethernet connectivity, Bluetooth, and two USB 3.0 ports. An auxiliary port is also included for connection to the PlayStation Camera, a motion detection digital camera device first introduced on the PS3. A mono headset, which can be plugged into the DualShock 4, is bundled with the system. Audio/video output options include HDMI TV and optical S/PDIF audio. The console does not have an analogaudio/video output.
The PS4 features a "Rest mode" feature. This places the console in a low-power state, while allowing users to immediately resume their game or app once the console is awoken. The console also is able to download content such as game and OS updates while it is in this state.
