Sony revealed additional details about its PlayStation 4 game console at the Game Developers Conference. One of the major improvements of the PS4 will be its storage sub-system, which will include faster Blu-ray disc drive as well as very hard capacity hard disk drive. Both will improve overall user experience by speeding up game installations and launches.
The PlayStation 4's Blu-ray disc drive is three times as fast as the PlayStation 3's, according to Engadget web-site. Keeping in mind that the PS3 is equipped with 2x BD drive capable of reading Blu-ray discs at up to 9MB/s speed. The three times faster solution is a 6x BD drive that can read discs at up to 27MB/s, which should be enough not only for modern games, but also for next-generation 4K video discs, assuming that they are Blu-ray or compatible with the drive (or use the same 405nm wavelength as BD).
Today’s PlayStation 3 systems are available with 160GB, 250GB, 320GB and 500GB hard disk drives. They PlayStation 4 is projected to feature “a very large hard drive in every console”, revealed Chris Norton, a senior staff engineer at Sony Computer Entertainment America, reports IGN web-site. Since the PS4 consoles will likely continue to use 2.5” hard drives, it is possible to expect 500GB, 750GB or 1TB HDDs in the PS4 simply because there are no standard drives in such form-factor with higher capacity now and Sony is unlikely to use the forthcoming drives based on newer platters in the consumer electronics device.
Other hardware related improvements that the engineer mentioned are all-digital buttons and sticks on the DualShock 4 controller, ability to charge the controller while the console is off as well as a mono headset in every PlayStation 4 box.
Sony PlayStation 4 is based on a semi-custom AMD Fusion system-on-chip that integrates eight AMD x86 Jaguar cores, custom AMD Radeon HD core with unified array of 18 AMD GCN-like compute units (1152 stream processors which collectively generate 1.84TFLOPS of computer power that can freely be applied to graphics, simulation tasks, or some mixture of the two), various special-purpose hardware blocks as well as multi-channel GDDR5 memory controller. The PS4 will come with 8GB of unified GDDR5 memory sub-system (with 176GB/s bandwidth) for both CPU and GPU as well as large-capacity hard disk drive.
Sony PS4 will be equipped with Blu-ray disc drive capable of reading BDs at 6x and DVDs at 8x speeds, USB 3.0 connectivity in addition to a proprietary aux port, Gigabit Ethernet port, 802.11b/g/n Wi-Fi, Bluetooth 2.1 EDR wireless technology as well as HDMI, optical and analog outputs. The new system will also utilize new DualShock 4 game controller with integrated touchpad as well as better motion sensing thanks to new PS4 Eye tracking cameras.
The PlayStation 4 is projected to be launched during holiday season 2013 in select regions.
