The PS4 was released in Japan at ¥39,980 on February 22, 2014. Sony finalized a deal with the Chinese government in May 2014 to sell its products in mainland China, and the PS4 will be the first product to be released.

." In September 2015, Sony reduced the price of the PS4 in Japan to ¥34,980, with similar price drops in other Southeast Asian markets. The first official sub-£300 PS4 bundle was the £299.99 "Uncharted Nathan Drake Collection 500GB", and was released in the UK on October 9, 2015; a 1 TB £329.99 version was offered at the same time. On October 9, 2015, the first official price cut of the PS4 in North America was announced: a reduction of $50 to $349.99 (US) and by $20 to $429.99 (Canada). An official price cut in Europe followed in late October 2015, reduced to €349.99/£299.99. On June 10, 2016, Sony confirmed that a hardware revision of the PlayStation 4, rumored to be codenamed "Neo", was under development. The new revision is a higher-end model that is meant to support gameplay in 4K. The new model will be sold alongside the existing model, and all existing software will be compatible between the two models. Layden stated that Sony has no plans to "bifurcate the market", only that gamers playing on the Neo will "have the same experience, but one will be delivered at a higher resolution, with an enhanced graphical experience, but everything else is going to be exactly as you'd expect". The high-end console was publicly revealed on September 7, 2016, as PlayStation 4 Pro. At the same time, Sony unveiled an updated version of the original PS4 model with a smaller form factor. In May 2018, during a presentation to investors, Sony Interactive Entertainment CEO John Kodera stated that the PlayStation 4 was heading into the end of its lifecycle and that the company was anticipating decreasing year-over-year hardware sales. He explained that Sony would be countering the expected decline by focusing on "strengthen nguser engagement" including continued investments into new first-party games and other online services for PS4. "We will use the next three years to prepare the next step, to crouch down so that we can jump higher in the future," Kodera added in an interview with the press the following day.

'' in January 2022, Sony had been poised to discontinue the PlayStation 4 at the end of 2021 in favor of the PlayStation 5, but due to the ongoing semiconductor shortage that made it difficult for Sony to keep up with PlayStation 5 demand, the company instead planned to continue PlayStation 4 production. Besides helping to offset the PlayStation 5 shortage, this production method would help assure deals with its component providers for the PlayStation 5.

Social features

Sony is focused on "social" aspects as a major feature of the console. Although the PS4 has improved social functionality, the features are optional and can be disabled.


Community creation

Users have the option to create or join community groups based upon personal interest. Communities include a discussion board, accomplishments and game clips shared by other members, plus the ability to join group chat and launch cooperative games. Sony stated that "communities are a good way to socialize with like-minded players", particularly when "you want to tackle a big multiplayer raid, but don't have enough friends available."Adam Westlake

Sony has officially stated that starting April 2021, the community system of the PlayStation Network will be discontinued. This, however, will not prevent users from communicating with their friends in private messaging or in group chats on the PlayStation Network.


Media sharing

The DualShock 4 controller includes a "SHARE" button, allowing the player to cycle through the last 60 minutes of recorded gameplay to select a screenshot or video clip appropriate for sharing. Media is uploaded seamlessly from the console to other PSN users or social networking sites such as

Share Play

Share Play allows users to invite an online friend to join their play session via streaming, even if they do not own a copy of the game. Users can pass control of the game entirely to the remote user or partake in cooperative multiplayer as if they were physically present. Mark Cerny says that remote assistance is particularly useful when confronted by a potentially game-defeating obstacle. "You can even see that your friend is in trouble and reach out through the network to take over the controller and assist them through some difficult portion of the game," he said. Share Play requires a PlayStation Plus subscription and can only be used for one hour at a time.Andrew Kelly

Backward compatibility

PlayStation 4 is not compatible with any disc of older PlayStation consoles. Emulated versions of selected PlayStation, PlayStation 2 and PlayStation Portable games are available for purchase via PlayStation Store, which are upscaled to high definition and have support for PS4 social features.

The United States Open Beta went live on July 31, 2014. The official United States release of the service was on January 13, 2015. PlayStation Now was in closed beta in the United Kingdom.

ExtremeTech says the PS4's graphics processing unit offers a "serious advantage" over the competition, but due to the nature of cross-platform development, games that share the same assets will appear "very similar". In other scenarios, designers may tap some of PS4's additional power in a straightforward manner, to boost frame rate or output at a higher resolution, whereas games from Sony's own first-party studios that take full advantage of the hardware "will probably look significantly better than anything on the Xbox One."

Hardware revisions

The PlayStation 4 has been produced in various models: the original, the Slim, and the Pro. Successive models have added or removed various features, and each model has variations of Limited Edition consoles.


PlayStation 4 Slim

On September 7, 2016, Sony announced a hardware revision of the PlayStation 4, model number CUH-2000, known colloquially as the PlayStation 4 Slim, which phased out the original model. It is a revision of the original PS4 hardware with a smaller form factor; it has a rounded body with a matte finish on the top of the console rather than a two-tone finish, and is 40% smaller in size than the original model. The two USB ports on the front have been updated to the newer USB 3.1 standard and have a larger gap between them, and the optical audio port was removed. This model also features support for USB 3.1, Bluetooth 4.0 and 5.0 GHz Wi-Fi. It was released on September 15, 2016, with a 500 GB model at the same price as the original version of the PlayStation 4. On April 18, 2017, Sony announced that it had replaced this base model with a 1 TB version at the same MSRP.


PlayStation 4 Pro

The PlayStation 4 Pro (codenamed Neo, model number CUH-7000) was announced on September 7, 2016, and launched worldwide on November 10, 2016. It is an upgraded version of the PlayStation 4 with improved hardware to enable 4K rendering and improved

s of processing power and hardware support for checkerboard rendering, and a higher CPU clock. As with PS4 "Slim", this model also features support for USB 3.1, Bluetooth 4.0 and 5.0 GHz Wi-Fi. The PS4 Pro also includes 1 GB of DDR3 memory that is used to swap out non-gaming applications that run in the background, allowing games to utilize an additional 512 MB of the console's GDDR5 memory.

. Games marketed by Sony as ''PS4 Pro Enhanced'' have specific optimizations when played on this model, such as 4K resolution graphics and/or higher performance. For games not specifically optimized, an option known as "Boost Mode" was added on system software 4.5, which can be enabled to force higher CPU and GPU clock rates on existing games to possibly improve performance. Rendering games at 4K resolution is achieved through various rendering techniques and hardware features; PlayStation technical chief Mark Cerny explained that Sony could not "brute force" 4K without compromising form factor and cost, so the console was designed to support "streamlined rendering techniques" using custom hardware, "best-in-breed temporal and spatial anti-aliasing algorithms", and "many new features from the AMD Polaris architecture as well as several even beyond it". The most prominent technique used is checkerboard rendering, wherein the console only renders portions of a scene using a checkerboard pattern, and then uses algorithms to fill in the non-rendered segments. The checkerboarded screen can then be smoothed using an anti-aliasing filter. Hermen Hulst of Guerrilla Games explained that PS4 Pro could render something "perceptively so close o 4Kthat you wouldn't be able to see the difference". PS4 Pro supports Remote Play, Share Play, and streaming at up to 1080p resolution at 60 frames per second, as well as capturing screenshots at 2160p, and 1080p video at 30 frames per second. In late 2017, Sony issued a new PS4 Pro revision (model number CUH-7100) that featured updated internal components. The actual hardware specifications and performance remained the same as the original model, although it was found that the revised console has a slightly quieter fan profile than the original (and as a result, operating at a slightly higher temperature under load than the CUH-7000). In October 2018, Sony quietly issued another revision (model number CUH-7200), initially as part of ''
