The design of the console was not revealed in the PlayStation Meeting, since the design and specifications were still not finalized. The weight of the console would be around 2.8 kg and the total box would be about 4 kg. The PlayStation 4 technology would be relatively similar to the hardware found in personal computers. At some point in the development it was contemplated that Nvidia was the one who manufactured the graphics unit for PS4 but according to statements by Tony Tamasi, vice president of content and technology of Nvidia this would not suit the company because of the impact it would have on its possibilities in other markets. With the decision to move the Cell architecture to x86-64 it would be easier and less expensive for studios to develop games for the PS4.The physical console was finally presented at the Sony conference on the PS4 on June 10, 2013 in E3 2013, as well as reveal more detailed data of the device and peripherals.
The PS4 video console has an eight-core x86-64 to 1.6 GHZ APU microprocessor manufactured by AMD under the codename Liverpool, based on the Jaguar architecture. An AMD 7870 GPU with a processing power of 1.84 Teraflops, which can be dedicated to different tasks that are not exclusively graphic. It also has a unified RAM of 8 GB, GDDR5, with a bandwidth of 176 GB / Second At the end of August 2013, Marc Diana, responsible for product marketing at AMD, told the specialized press that PS4 supports access to HUMA memory (heterogeneous UMA), which allows access to the two components of the APU , CPU and GPU, to the same memory locations simultaneously by using consistent caches. While AMD disallowed Diana’s statements, she did not deny them.
While the type of hard drive was unknown, the capacity would be in the already announced 500GB model, it was learned that the optical drive would support Blu-ray 6x and DVD 8x. In terms of connectivity, the console would have Ethernet (10BASE-T, 100BASE-TX, 1000BASE-T), 802.11 b / g / n and Bluetooth 2.1 (with EDR). It would offer HDMI ports, digital optical output and USB 3.0 (2X).
Warning system for overheating
The PS4 console has an early warning system that warns when the console begins to raise the temperature due to lack of air circulation, indicating it with a red light instead of blue in the console status bar, additionally a warning appears in display showing the alert about the rise in operating temperature. With this system, deterioration and subsequent failure of the console due to excessive temperature could be avoided, something that happened in some of the first console units manufactured in the previous generation.
