The PlayStation 4 will utilize a semi-custom accelerated processing unit (APU) developed by AMD in coordination with Sony.[16] The PS4 APU will be a single-chip solution that combines a CPU and GPU, as well as other components such as a memory controller and video decoder.[16] The central processing unit (CPU) will consist of eight x86-64 cores based on the upcoming Jaguar CPU architecture from AMD.[16] This processor marks a change from the "powerful but difficult to develop for" Cell processor found in the PlayStation 3.[17] The graphics processing unit (GPU) will consist of 18 compute units to produce a theoretical peak performance of 1.84 TFLOP/s.[11] This computing power can be used for graphics, physics simulation, or a combination of the two. Eurogamer calls the graphics technology in the PlayStation 4 "impressive" and an improvement from the difficulties developers experienced on the PlayStation 3.[18] The console will also include a secondary custom chip which will handle tasks associated with downloading, uploading, and social gameplay.[19][20] These tasks can be handled seamlessly in the background during gameplay or while the system is in sleep mode.[21]

The PS4 will contain 8 GB of GDDR5 unified system memory with a maximum bandwidth of 176 GB/s.[11][22] This is 16 times the amount found in the PS3, and is expected to give the console considerable longevity.[18][13] The unified memory architecture allows the CPU and GPU to access a consolidated memory, removing the need for separate, dedicated memory pools. The non-unified memory architecture of the PS3 was reportedly problematic.[18]

The read-only optical drive will read Blu-ray discs at 6x CAV for a maximum read speed of 27MB/s – a significant upgrade from the PS3's 2x speeds that were capped at 9MB/sThe DualShock 4 will be the PlayStation 4's controller. It is similar to the DualShock 3, with several new features. One new feature is a built-in two-point capacitative touch pad on the front of the controller, which can be clicked.[30] The controller will support motion detection via a three-axis gyroscope and three-axis accelerometer and vibration.[30] It will include a non-removable,[31] rechargeable lithium-ion battery tentatively capable of storing 1000 mAh.[30] The tentative design weighs 210 g (7.4 oz) and has dimensions of 162 × 52 × 98 mm (6.4 × 2.0 × 3.9 in).
