Understanding the Functionality of the PlayStation 4

The highly anticipated PlayStation 4 launched on November 15, 2013, under immense pressure to deliver a product that's meant to bring excitement and enjoyment. In a gaming industry facing uncertainty, and with Sony struggling financially, the PS4 carries the weight of not only saving its parent company but also revitalizing the entire console gaming market. This scenario could easily be the plot of an intense business strategy simulation... but this is very much real life.

Despite the immense pressure, the PS4 has created quite a stir among gamers, developers, and industry experts alike. It's important to remember that it had been six years since the PlayStation 3 made its debut. Since then, the gaming landscape has undergone dramatic transformations, akin to Super Mario battling a final boss in an ever-changing world.

At a time when smartphones were just a spark of an idea for Apple and tablet computers seemed like a far-off fantasy, today’s most popular games are no longer confined to gaming consoles. Instead, they’ve found their home on sleek mobile devices that offer the convenience of Internet access wherever you go.

As Sony approached the development of the PS4, it sought to respond to the rise of smartphones and tablets. The company outlined five core principles to guide the project: simplicity, immediacy, social connectivity, integration, and personalization.

One example of these principles in action is the new PS4 controller, which includes a Share button. With a simple press, you can instantly broadcast your gameplay to friends on the PlayStation Network. Your friends can watch your victories, offer words of encouragement, and, if needed, even step in to help when you’re struggling. Additionally, you and your friends can easily record and share clips of both your triumphs and your worst moments in the game.

This is just one feature of what Sony envisions as a console gaming masterpiece. However, like all console systems, it all starts with the hardware. And as you’ll soon discover, the PS4 is less of a traditional gaming console and more of a personal computer.

The Console as PC

A great deal of the excitement surrounding the PS4 kicked off with a February 2013 press conference, where some of the system's internal specs were unveiled. It became immediately apparent that Sony was stepping away from some of its past choices to build this next-generation console.

For the PS4, Sony abandoned the Cell architecture from the PS3 era. While the system offered impressive power for gaming, it posed challenges for developers. The PS4, on the other hand, is powered by the x86 architecture, the same platform commonly used in modern PCs. Sony believes this transition will lead to quicker and simpler development for game creators.

Under the PS4's hood, you'll find an 8-core AMD Jaguar X86 64-bit processor, along with a substantial amount of RAM—8GB of GDDR5 (Graphics Double Data Rate, version 5) RAM.

Importantly, this RAM is shared between the 64-bit CPU and an AMD Radeon GPU (Graphics Processing Unit). Although the specific model of the GPU has not been disclosed, Sony revealed that it delivers around 2 teraflops of computing performance.

Putting the technical jargon aside, what this means is that with the PS4, you’re essentially getting a high-powered desktop computer—one specifically designed to optimize graphics-heavy gaming.

There are even more intricate technical details about the PS4. On the following page, you'll explore how Sony is pushing the boundaries of gaming innovation.

Stereo Eyes and Harder Shocks

The PS4 comes equipped with a Blu-ray optical drive that can read at speeds of up to 27MBps (megabytes per second), which is roughly three times faster than the PS3's. In addition, the console offers a wide range of connectivity options, such as Ethernet, WiFi, and Bluetooth, and will feature USB 3.0 ports, though the exact number wasn't disclosed as of March 2013.

Each PS4 includes an upgraded PlayStation Eye, resembling a sleek webcam mounted on top of your TV. The Eye now offers stereo vision with two 1280 by 800 resolution cameras. Much like the Microsoft Kinect, it can track your movements and gestures for game input, as well as record video with one camera while tracking motion with the other.

The Eye also features four built-in microphones, which can be used for voice commands. It's linked to facial recognition software, allowing you to log into the system without needing a password.

The new DualShock 4 controller connects to the console via Bluetooth, maintaining the same design of a gamepad with two joysticks as the previous version. However, it also includes a touchpad for additional input and a multi-colored light bar that can be customized to represent player-specific colors or signal in-game cues. You'll also receive notifications through the integrated speaker.

The DualShock 4 controller comes with a mm jack for the included headset, and also features a microUSB port.

Beyond the technical specifications, the PS4 also introduces some exciting new features on the software front. Keep reading to discover how Sony plans to captivate both new and long-time gamers.

Downloadable and Portable

Nowadays, even those who aren't gamers find themselves surrounded by glowing gadgets, from laptops to tablets to smartphones. The PS4 taps into this trend. For example, if you're in the middle of a game and need to step out, you can switch from your TV to your portable PlayStation Vita. Or, if you're staying at home, you can link your smartphone or tablet to the system, using these devices as second-screen accessories to enhance gameplay. While not all games will offer this feature right away, Sony is hopeful that developers will take full advantage of the PS4's social capabilities.

Even the way you buy games is evolving. In the past, you'd visit a big box store, pay around $50 for a physical disc, or order one online. With the PS4, every game is downloadable, with prices ranging from a few dollars to those you’d pay for traditional physical discs.

Some games might take a while to download because of their large file sizes, but no worries! The PS4 is designed to let you start playing even while the game continues downloading in the background. If you're unsure about buying a game, you can stream demos directly from the Internet. As the PS4 learns your gaming preferences, it will even pre-load demos of games it thinks you’ll enjoy.

When you decide it's time for a break from gaming, you can easily switch to movie or TV show mode. While specifics are still limited, you'll likely be able to stream content from Amazon Instant Video and Netflix directly through the PS4 interface. Alternatively, you can open a web browser and browse the internet without needing to switch to your PC.

It will probably take years before we know how Sony's PS4 gamble plays out. This might be one of the final major console launches focused primarily on hardcore gamers. On the other hand, the PS4 could prove that these classic entertainment devices still have staying power. Either way, it’s safe to say the PS4 packs enough tech to result in plenty of late-night gaming sessions, leaving fingers tired and eyes bleary.
