In an interview with Wired Magazine in April 2019, Sony lead architect Mark Cerny revealed information on the then-unnamed successor to the PlayStation 4. The PlayStation 5 (PS5) as it has come to be known as, is an upcoming home video game console developed by Sony Interactive Entertainment to be launched in late 2020. Here are the things you need to know about the PS5.

The PlayStation 5 uses AMD’s 7nm Zen 2 microarchitecture with 8 CPU cores running at a variable frequency capped at 3.5 GHz. The GPU is a customized system-on-a-chip (SoC) based on AMD’s RDNA 2, featuring 36 compute units running at a variable frequency, capped at 2.23 GHz, and capable of 10.28 TFLOPS. Both the CPU and GPU are monitored by a special boost system incorporating AMD’s SmartShift technology that adjusts the frequency of these systems based on the current activities of both chips, to target ideal constant power drawn and a model SoC performance profile. The GPU supports hardware acceleration of real-time ray-traced rendering
It also has a new audio technology called Tempest Engine, which allows not only for hundreds of sound sources within a game to be accounted for in producing audio output compared to 50 for the PlayStation 4, but also how that audio is presented based on the end user’s device and preferences. The system has 16 GB of GDDR6 SDRAM with a bandwidth of 448 GB/s.

There is a custom SSD storage solution that was designed for the PlayStation 5 to increase data input/output rates for fast loading times and larger bandwidth. The base system has an 825 GB SSD connected via a 12-channel interface to the main system, achieving a 5.5 GB/s transfer rate uncompressed, and between 8 to 9 GB/s using compression with the Oodle Kraken protocol from RAD Game Tools. Direct storage for games is expandable through an NVM Express (NVMe) M.2 port, while additional storage can be made available through USB-compatible drives. The system includes a 4K-compatible Ultra HD Blu-ray optical drive.

The new PS5 has an added feature – DualSense Controller. This has strong haptic feedback through voice coil actuators, which together with an improved controller speaker is intended to give better in-game feedback. It also has adaptive triggers that can change the resistance to the player as necessary. A new built-in microphone array was added so players can speak to others using only the controller. It has two-tone coloring, which is primarily white with black facing. It has USB-C connectivity, a higher-rated battery, and an audio jack.

The PS5 has a revamped user interface that is characterized as accessible and informative, providing real-time updates so the player doesn’t have to search or wait to discover friends’ activities, available multiplayer activities, and what single-player missions and rewards are available.

Some of the games in the PS5 includes: Assassin’s Creed Valhalla (Ubisoft), Godfall (Gearbox Publishing), Gods and Monsters (Ubisoft), The Lord of the Rings: Gollum (Daedalic Entertainment), Outriders (People Can Fly), World Rally Championship 9 (Bigben Interactive) and others.
