Both Sony and Microsoft are already working on the next iteration of their rival games consoles. The chief technical officer for Sony Computer Entertainment this week told a games conference that the PlayStation 3 will use a form of distributed computing to boost performance, according to CNet news.

Shin’ichi Okamoto told attendees at the annual Game Developers Conference that chip speeds are accelerating too slowly for Sony’s liking. Instead, distributed computing will be used, which will involve networked consoles sharing software, processing power and data.

Meanwhile, a research note from Boston investment bank Fechtor Detwiler is quoted by The Register.co.uk, speculating that Microsoft will abandon Intel as chip provider for its Xbox 2 in favour of chip rival AMD.
