PS3 to Have Processing Power of 100 PCs

SAN JOSE, Calif. -- Sony's next-generation video-game console, due in just two years, will feature a revolutionary architecture that will allow it to pack the processing power of a hundred of today's personal computers on a single chip and tap the resources of additional computers using high-speed network connections.
If key technical hurdles are overcome, the "cell microprocessor" technology, described in a patent Sony quietly secured in September, could help the Japanese electronics giant achieve the industry's holy grail: a cheap, all-in-one box for the home that can record television shows, surf the Net in 3D, play music and run movie-like video games.
Besides the PlayStation3 game console, Sony and its partners, IBM and Toshiba, hope to use the same basic chip design -- which organizes small groups of microprocessors to work together like bees in a hive -- for a range of computing devices, from tiny handheld personal digital assistants to the largest corporate servers.
If the partners succeed in crafting such a modular, all-purpose chip, it would challenge the hegemony of Intel and other chipmakers that make specialized chips for each kind of electronic device.
"This is a new class of beast," said Richard Doherty, an analyst at the Envisioneering Group in Seaford, N.Y. "There is nothing like this project when it comes to how far-reaching it will be."
Game industry insiders became aware of Sony's patent in the past few weeks, and the technology is expected to be a hot topic at the Game Developers Conference in San Jose this week. Since it can take a couple of years to write a game for a new system, developers will be pressing Sony and its rivals for technical details of their upcoming boxes, which are scheduled to debut in 2005.
Ken Kutaragi, head of Sony's game division and mastermind of the company's last two game boxes, is betting that in an era of networked devices, many distributed processors working together will be able to outperform a single processor, such as the Pentium chip at the heart of most PCs.
With the PS3, Sony will apparently put 72 processors on a single chip: eight PowerPC microprocessors, each of which controls eight auxiliary processors.
Using sophisticated software to manage the workload, the PowerPC processors will divide complicated problems into smaller tasks and tap as many of the auxiliary processors as necessary to tackle them.
"The cell processors won't work alone," said Doherty. "They will work in teams to handle the tasks at hand, no matter whether it is processing a video game or communications."
As soon as each processor or team finishes its job, it will be immediately redeployed to do something else.
Such complex, on-the-fly coordination is a technical challenge, and not just for Sony. Game developers warn that the cell chips do so many things at once that it could be a nightmare writing programs for them -- the same complaint they originally had about the PlayStation2, Sony's current game console.
Tim Sweeney, CEO of Epic Games in Raleigh, N.C., said that programming games for the PS3 will be far more complicated than for the PS 2 because the programmer will have to keep track of all the tasks being performed by dozens of processors.
"I can't imagine how you will actually program it," he said. "You do all these tasks in parallel, but the results of one task may affect the results of another task."
But Sony and its partners believe that if they can coordinate those processors at maximum efficiency, the PS3 will be able to process a trillion math operations per second -- the equivalent of 100 Intel Pentium 4 chips and 1,000 times faster than processing power of the PS2.
That kind of power would likely enable the PS3 to simultaneously handle a wide range of electronic tasks in the home. For example, the kids might be able to race each other in a Grand Prix video game while Dad records last night's "Simpsons" episode.
"The home server and the PS3 may be the same thing," said Kunitake Ando, president and chief operating officer of Sony, at a recent dinner in Las Vegas.
Sony officials said that one key feature of the cell design is that if a device doesn't have enough processing power itself to handle everything, it can reach out to unused processors across the Internet and tap them for help.
Peter Glaskowsky, editor of the Microprocessor Report, said Sony is "being too ambitious" with the networked aspect of the cell design because even the fastest Internet connections are usually way too slow to coordinate tasks efficiently.
The cell chips are due to begin production in 2004, and the PS3 console is expected to be ready at the same time that Nintendo and Microsoft launch their own next-generation game consoles in 2005.
Nintendo will likely focus on making a pure game box, but Microsoft, like Sony, envisions its next game console as a universal digital box.
A big risk for Sony and its allies is that in their quest to create a universal cell-based chip, they might compromise the PS3's core video game functionality. Chips suitable for a handheld, for example, might not be powerful enough to handle gaming tasks.
Sony has tried to address this problem by making the cell design modular; it can add more processors for a server, or use fewer of them in a handheld device.
"We plan to use the cell chips in other things besides the PlayStation3," said Ando. "IBM will use it in servers, and Toshiba will use it in consumer devices. You'd be surprised how much we are working on it now."
But observers remain skeptical. "It's very hard to use a special-purpose design across a lot of products, and this sounds like a very special-purpose chip," said Glaskowsky.
The processors will be primed for operation in a broadband, Net-connected environment and will be connected by a next-generation high-speed technology developed by Rambus of Los Altos.
Nintendo and Microsoft say they won't lag behind Sony on technology, nor will they be late in deploying their own next-generation systems.
While the outcome is murky now, analyst Doherty said that a few things are clear: "Games are the engine of the next big wave of computing. Kutaragi is the dance master, and Sony is calling the shots."

So far this sounds EXACTLY like PS2 hype. All we need is Geroge Lucas gushing about it and we're there.

I will never take anything Ken Kutaragi says seriously. This is the man that claimed that we would be able to plug our brains into our PS2s and enter a "Matrix-like" reality. The man's a fucking insane dildo.

Listen to the developers for once, Sony.

Good idea.

Great...does this mean that many PS3 games will have jaggies and weak textures too? ;)

Well, at least we all know for sure that Nintendo will be releasing another console. As weird as it was having Sega turn thrid-party it would be ever weirder if Nintendo did it.
If I sound like I'm Sony bashing, I'm not. I like the PS2, it has a lot of great games. But I'm just sick of the Sony hype machine...
