Being based on low-power/low-cost microprocessor technology and current-generation graphics processing technology from Advanced Micro Devices, Sony PlayStation 4 will unlikely offer horsepower comparable to even today’s gaming PCs. However, the PS4 has a secret weapon that even high-end PCs will not sport for a couple of years: 8GB of GDDR5 memory. As it appears, game developers believe in this feature.
“[PlayStation 4] is a perfect fit for the types of games we do, and we are confident that we will bring open-world gaming to a whole new level because of it. I am glad Sony decided to go with 8GB GDDR5 RAM because it means that the PS4 will out-power most PCs for years to come,” said Linus Blomberg, chief technology officer and co-founder of Avalanche Studios, in an interview with Gamingbolt web-site.
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.
Even by today’s standards Sony PlayStation 4 can be considered as an entry-level gaming system and is significantly behind mainstream and high-end machines. Still, when compared to average PCs, which feature dual-core microprocessors, integrated or entry-level graphics as well as around 4GB of DDR3 memory, then Sony’s PS4 is a powerhouse.
Still, PS4 is not only about pure performance, but also about other features and capabilities.
“The PS4 will not only be a very powerful gaming machine from a hardware perspective, but it will also be a social tool and integrated marketplace more akin to the successful mobile devices. It’s the best of all worlds in a way; great performance for demanding high-end gaming, good social ecosystem and connectivity, and integrated business marketplace,” added Mr. Blomberg.
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.
