AMDs chief graphics architect really likes the PlayStation 4
While at GDC, I had the chance to sit down and speak with AMDs chief graphics product architect, John Gustafson. While he remained silent when it came to Microsofts next generation Xbox, he had a lot to say about Sonys recently announced PlayStation 4.
“The PlayStation 4 blew me away but Im conscious about being too positive about it because of course we have other partners that are competing,” said Gustafson at GDC (Game Developers Conference) in San Francisco.
During their big PlayStation 4 reveal back in February, Sony revealed that rather than creating their own hardware like they did with the PlayStation 3, the PlayStation 4 will adopt AMD created chipsets.
AMD also provides the graphics horsepower behind the Wii U, a fact Gustafson was quick to point out when asked about his feelings on the PlayStation 4 and the fact that its the only true next-generation console thats been revealed so far. “Of course there is the Wii U too, we have AMD parts in there,” said Gustafson.
He also seems to be very impressed with the specifications Sony has revealed so far about the PlayStation 4.
“It looks like they did an extremely good job of the engineering… The CPU and the GPU are on the same chip, which solves a lot of the problems (you dont have to toss things over to a graphics card and try to get them back and forth).”
Going into specifics, Gustafson explained how he expects next generation physics engines on the PlayStation to be more realistic than weve ever seen before. He also emphasized that the consoles 8 GBs of ram will give developers a significant amount of breathing room when it comes to game development.
Gustafson also expanded on the potential he thinks the PS4 has when it comes to purposes outside of gaming, especially if it were used as some sort of server. According to him, all it would take is a few modifications and youd have an amazing computer platform for all kinds of purposes.
Since the PS4′s architecture is so similar to that of a high-end PC, once hackers get their hands on the actual console, I imagine it wont be long before they find a way to turn it into an actual computer, allowing it to become more than just a game console

PlayStation 4 developers have access to 7 GB RAM: rumor
The PlayStation 4 will ship with a massive 8 GB of GDDR5 memory, which is a huge upgrade compared to the current generation consoles. However, according to a PlayStation 4 developer PS4Daily spoke to, they have access to “only” 7 GB of RAM. The remaining 1 GB is reserved for the operating system and background tasks.

''On PS4′s APU where the data in memory can be manipulated either by the GPU or CPU or in sequence without any performance hits due to data transfer, CPU can pre-process data using branch-heavy algorithms and hand it off to the GPU, or the GPU could pre-process data for the CPU. Its like a super-efficient tag team. Mark Cerny, in an interview with the Japanese press, mentions that these features arent put to use in the launch titles, but will be something that opens up new possibilities later on''
