hey guys, just got this through work and thought alot of you might want to read it...

After reading this i am very interested to see what MS comes out with for the Xbox 2!

PlayStation 3: Supercomputer-On-A-Chip
Sony's next iteration of the venerable PlayStation may be "Cell-bound."
By Chuck Miller | Jan. 11, 2003

Having concluded a record-breaking sales season during November and December 2002 on its PlayStation 2 video game system (selling over four million PS2 hardware units and more than 400,000 PlayStation 2 Network Adaptors), Sony is in the news again with regard to the next iteration of its PlayStation console, the PlayStation 3.

Destined by all indicators for a 2005 release, stories surround the PS3 pointing toward the incorporation of a complex microprocessor, a supercomputer-on-a-chip bearing the moniker "Cell." Being championed by the hardware triumvirate of IBM, Sony, and Toshiba, these companies have pledged $400 million to the project.

Cell, scheduled to hit the market in late 2004 or early 2005, differs notably from current processors. This finely crafted chunk of silicon will contain multiple chips within a single unit, and will be able to perform in excess of one trillion mathematical calculations a second. Put into perspective, that makes it approximately 100 times more powerful than a 2.5 GHz Pentium 4 CPU!

At present, the processor's design is still being held tightly under wraps, but sources indicate that in addition to its ability to deliver one trillion calculations per second or more of floating-point calculations, Cell will likely employ somewhere between four and 16 processor cores, or cells, per chip (hence the technology's label). Accordingly, while a game console might utilize a chip with 16 cores (some cores performing computational functions, others controlling audio and graphics), a less complicated "appliance" like a set-top box would require fewer. At least, that's a précis offered by Peter Glaskowsky, editor in chief of the influential industry newsletter "Microprocessor Report."

Cell computing will also facilitate a distributed style of networking that performs computing tasks in much the same way a cell phone network routes calls. Thus, for example, the PlayStation 3 will be able to use its broadband Internet connection to draw additional computing power from idle processors across the Internet. If still more horsepower is required, the PlayStation 3 can even tap into a home network to enlist support from other available machines. Put simply, Cell allows pieces of a computing task to be distributed among all available processors to harness their combined power.

This all dovetails with comments made by Shin'ichi Okamoto, chief technical officer for Sony Computer Entertainment, during a speech made at the 2002 Game Developers Conference. He spoke then of a technology he referred to as parallel computing, where multiple processors dramatically increase performance by splitting tasks. Okamoto also showed a diagram of an early project referred to by Sony as "GScube" comprised on 16 PS2s paired with a video merger and integrated into a single box. And, he went on to hint at a project that Sony was working on with IBM and Toshiba regarding a "cell processor," a technology that Okamoto confirmed would be at the core of the third-generation PlayStation.

This supercomputer-on-a-chip, however, is in need of external technology that will enable the high-speed interfacing between chips that it requires to perform its magic. That's where Rambus comes in. Best known for the RDRAM employed in PCs and game consoles (Nintendo and Sony), Rambus specializes in chip interfaces, electronic ports that facilitate the communication between chips. This past year, it licensed its memory technology to Sony and Toshiba, companies which plan to use it in "unspecified" new products due to reach market in approximately three years. Understandably, shares of both companies jumped based on speculation that Rambus' technology will be employed in combination with Cell in Sony's PlayStation 3.

The communication technologies in question are known as "Yellowstone," a high-speed interface for connecting memory to microprocessors, and "Redwood," a chip-to-chip connection. Both are capable of readily enhancing the broadband capabilities of Cell, a necessity since processors moving data at the rate Cell is capable of need to be augmented by high-speed links and similarly rapid chips in order to function at full capacity. Yellowstone, for instance, can transfer data at speeds of up to 100 gigabits per second -- three times the speed of current high-speed memory. As part of the deal, Rambus will receive royalties estimated at $28 million over the next 18 months. Furthermore, the license is non-exclusive, meaning that Nintendo and Microsoft could both utilize the technology for their respective next-generation consoles should they choose to do so.

Additionally, due to Cell's architecture, it's likely that the chip will replace the dedicated graphic processors traditionally employed in consoles. The PS3, including other devices that will employ Cell, will benefit by the CPU's "self healing" capability, too. Its bus and processor areas will be automatically corrected using a new "meshed era redundancy technology" to keep the systems from going down. Further, Cell will incorporate advanced research technologies and chip-making techniques, including ultra-thin copper wires, silicon-on-insulator (SOI) transistors, and low-K dielectric insulation.

Industry analysts have confirmed that the timeline for Cell's arrival coincides with plans to release the PlayStation 3 in 2005. However, plans are also rumored to be in the works for Cell to appear in PCs, scheduled for initial release in Sony's Vaio line of personal computers. There's also a good likelihood that this über-processor will be coupled with the new format of media playback known as "Blu-Ray Disk." It employs a blue laser and is capable of realizing a capacity of 25 to 27 GB per recording layer on a DVD. That's up to 50 GB on a double-sided disk.

Of course, while Cell will be a boon for gaming, it offers benefits beyond this arena extending to all areas of entertainment -- downloading games from the Internet, tapping into vast networks of movies and music, recording TV shows, and engaging in e-commerce. With added power comes added flexibility. It also provides Sony, in particular, with some unique opportunities with its next generation PlayStation and their other entertainment products such as high-definition televisions and digital camcorders.

At this juncture, there's still much to do in prepping Cell for market, and specifically, for use in the PS3. While the chip's inner workings have all been designed, prototype chip testing is just getting underway. Software development has a long road ahead of itself, as well. For now, gamers will simply have to wait and look forward two to three years down the line to a new console that will be exponentially more powerful than their current PS2. •

Edit: cleaned it up a bit.

this was rumoured to be happening a few months ago, i think someone posted it on here somewhere (sounds like a very similar article, from memory). it'll be interesting to see exactly how long they take to actually deliver on this promise, it sounds like it'll be worth getting though! ;D

Sounds like crap-o-la to me.

What good is distributed computing to a games console?

Is it going to find a cure for AIDS in between levels on GTA4?

Pfft.

Personally, I'm going to hold out for this sexy bit of kit! (http://www.theonion.com/onion3847/ghost_of_christmas_future.html)

so i take it you have never heard of online or network gaming??

me thinks not from the above post.

this is more or less real.

of course, whether it lives up to its performance claims is another issue... also, we're looking at some very very complex distributed applications to take advantage of this sort of architecture,its hard enough coding a multithreaded application let alone a fully distributed one.

the ps3 is *not* going to be an easy beast to code for if what they are talking about is true.

i just hope they realise that throughput isnt everything, and latency in memory/cpu applications counts a lot too...

but it does give you a glimpse of where computer architecture is heading.. multiple cores on a single die, its all good..

i dont believe anything until i see it running. Every console gets hyped to the shitter. N64 = graphics that would rival a silicone work station, well we all know how great the graphics were on that. "am i wearing my glasses, the screens all blurry?? oh no thats just the pissy amount of texture ram." PS2 was said to deliver graphics that could replicate Toy Story 2 in real time, yeh right.

i'm not that overly impressed by the new generation of consoles. PS2 !!STILL!! has anti-aliasing problems, X-Box can produce what i would suggest are the best graphics, however the games dont appeal to me all that much as their mostly PC ports or PC style games and Nintendo STILL insist on making Kiddie games, whilst thats not entirely bad, the gameplay is great but the games are too easy and they never release any decent realistic racers. My personal preferance of all these consoles would still be the Dreamcast, it might not be able to match the other systems in terms of graphics (i reckon it would still put the PS2 thru its limits tho, as the chip has far more trickery so as to make it look like its running harder then it is, not to mention the texture mapping SHITS all over the PS2, same with its anti-aliasing).

ok i sound biased, but i own a PSX, PS2, N64 and dreamcast. christmas i was recently able to pick up the PS2 i have now or the X-Box or Gamecube. however being a serious car nut the best racing games were all on PS2, same with the RPG's. most of the initial X-Box games were prettied up versions of their Dreamcast counterparts and Gamecubes initial selection is....errrrr.....just shit for now anyways

err basically, i pick a system for its games, Dreamcast, which the ones who dared buy the system discovered, probly had the most innovative games for a long while. PS2 i got for the racing games, X-Box i doubt i would ever buy, i'd rather upgrade my PC, and the Gamecube i will look into with the release of the next Zelda installment. basically find the system with has the most games that appeal to you and go from there. best graphics dont mean best games, i'm still hooked on The Legend Of Zelda (yes, the NES one) and am desperately trying to find someone who can resuscitate my megadrive. Dreamcast tho is still the best system i have ever owned and appealed to me the most, even now still. You'd be a right knob to not appreciate the art that was Shenmue. was supposed to be a 7 part series but hey, since noone bought the Dreamcast i have to settle with Shenmue 1 and hopefully track down a US version of Shenmue 2
