Mark Cerney, Lead System Architect on PlayStation 4 - you may have seen him when Sony launched the idea of the console or heard him when he slagged off the design process of the PS3. Well, he's been chatting techy-like about the PS4's Supercharged PC Architecture.
"We started to design the PS4 in 2008. Since then, we had discussions with many companies on the adoption of any technology", he begins, thereby giving the new console both history and a future in one go. But basically it boils down to the fact that he opted to use Single Chip Custom Processor which have eight Jaguar x86 64-bit CPUs made by AMD." Why?
"We made that decision from the viewpoints of technology, time and business", he says. He tells Technon
in Japan, that "The adoption of the x86 architecture made it much easier to develop game software because enough toolchains, numerical libraries and software that utilizes multimedia instructions are available for it."
The chip and as importantly the memory ("Though it is a challenge in terms of cost and procurement, we decided to offer a memory capacity of 8 Gbytes because of strong demand from developers", he says of the 16 4-Gbit GDDR5 memory chips used in the new console) are aimed at making things "easy for developers to create games so that many games will be made."
"We received very positive responses to the concept of 'Supercharged PC Architecture' from developers because we made a drastic improvement to performance and made it easy to develop games at the same time. It is hardware for which games can be developed really easily."
