Microprocessor Challenge to Intel

Setting up a battle for the future of computing, engineers from IBM, Sony and Toshiba unveiled details of a microprocessor they claim has the muscle of a supercomputer and can power everything from video game consoles to business computers.

Devices built with the processor, code-named Cell, will compete directly with the PC chips that have powered most of the world's personal computers for a quarter century. Cell's designers say their chip, built from the start with the burgeoning world of rich media and broadband networks in mind, can deliver 10 times the performance of today's PC processors.

It also will not carry the same technical baggage that has made most of today's computers compatible with older PCs. That architectural divergence will challenge the current dominant paradigm of computing that Microsoft Corp. and Intel Corp. have fostered.

The new microprocessor also is expected to be able to run multiple operating systems and programs at the same time while ensuring each has enough resources. In the home, that could allow for a device that's capable of handling a video game, television and general-purpose computer at once.
