There are small but noticeable changes with the new DualShock. It seems to have rounded out a bit, fitting the hand much better than the previous design, which Sony hadn’t changed much in two generations. The analog sticks have a recessed dome on top to reduce slippage and the L2 and R2 buttons curve towards your fingers rather than away for a more trigger-like feel. Instead of “Start” and “Select,” an “Options” button takes over and a “Share” button is introduced.
The PlayStation 4 Hardware
AMD is producing a single APU chip that combines a CPU and GPU (among other things) and contains eight x86-64 cores. The GPU can push out 1.84 teraflops through 18 compute units in a unified array, meaning they can be used for graphics, simulation, or both. The big standout bit of hardware is 8GB of unified 256-bit GDDR5 system memory, a huge change from the PlayStation 3’s two disparate 256MB pools. It’ll rock a user-upgradable 500GB HDD.
PlayStation 4’s Operating System
The XrossMediaBar of the PS3 will be replaced with the FreeBSD 9-based PlayStation Dynamic Menu. The home screen shows personalized content from friends, while user profiles display recent activity and trophies, and game pages highlight related content and compatible friends. The new OS makes multitasking possible, and will facilitate streaming games and sharing media. The onscreen keyboard is a popup with predictive text and sweeping analog control.
Rather than make additions to the controller, Microsoft has opted for iterative improvements, the most prominent of which are the Impulse Triggers, a pair of triggers that can rumble independently of the controller body for subtle but more directed feedback. The controller’s shape has flattened out a bit and become more angular, but that also means the removable battery pack is now flush with the rest of the controller.
The Xbox One Hardware
Though it will also feature a custom eight-core x86-64 APU, the Xbox One will see 8GB of DDR3 RAM, putting its memory bandwidth at 68.3 GB/s instead of 176 GB/s. The GPU, based on AMD’s GCN architecture, will feature 12 compute units for 1.31 teraflops. It will also have a500 GB HDD and, finally, a Blu-ray drive.
Xbox One’s Operating System
Microsoft’s approach to the Xbox One includes a hybrid of three operating systems. The console will run an Xbox OS and a version of Windows OS, with a third system working as a hypervisor. While Windows apps will not be directly compatible with Xbox One, they can be easily ported over thanks to the cut-back Windows version on the console. Xbox One will feature a redesigned Metro-style interface with tiles to display recommended and recent media, apps and games. The bundled Kinect 2.0 sensor allows for as many as six player profiles to be signed in at once. Multitasking is supported with the ability to snap apps alongside other activities, and the Kinect also supports voice commands for menu navigation and launching apps.
