IBM, Sony, Sony Computer Entertainment Inc. and Toshiba Disclose Key Details of the Cell Chip
Monday February 7, 1:00 pm ET
Innovative Design Features Eight Synergistic Cores Together with Power Based Core, Delivers More Than 10 Times the Performance of the Latest PC Processors

SAN FRANCISCO--(BUSINESS WIRE)--Feb. 7, 2005-- At the International Solid State Circuits Conference (ISSCC) today, IBM, Sony Corporation, Sony Computer Entertainment Inc. (Sony and Sony Computer Entertainment collectively referred to as Sony Group) and Toshiba Corporation (Toshiba) for the first time disclosed in detail the breakthrough multi-core architectural design - featuring supercomputer-like floating point performance with observed clock speeds greater than 4 GHz - of their jointly developed microprocessor code-named Cell.

A team of IBM, Sony Group and Toshiba engineers has collaborated on development of the Cell microprocessor at a joint design center established in Austin, Texas, since March 2001. The prototype chip is 221 mm(2), integrates 234 million transistors, and is fabricated with 90 nanometer SOI technology.

Cell's breakthrough multi-core architecture and ultra high-speed communications capabilities deliver vastly improved, real-time response for entertainment and rich media applications, in many cases 10 times the performance of the latest PC processors.

Effectively a "supercomputer on a chip" incorporating advanced multi-processing technologies used in IBM's sophisticated servers, Sony Group's computer entertainment systems and Toshiba's advanced semiconductor technology, Cell will become the broadband processor used for industrial applications to the new digital home.

Another advantage of Cell is to support multiple operating systems, such as conventional operating systems (including Linux), real-time operating systems for computer entertainment and consumer electronics applications as well as guest operating systems for specific applications, simultaneously.

Initial production of Cell microprocessors is expected to begin at IBM's 300mm wafer fabrication facility in East Fishkill, N.Y., followed by Sony Group's Nagasaki Fab, this year. IBM, Sony Group and Toshiba expect to promote Cell-based products including a broad range of industry-wide applications, from digital televisions to home servers to supercomputers.

Among the highlights of Cell released today:

* Cell is a breakthrough architectural design -- featuring eight synergistic processors and top clock speeds of greater than 4 GHz (as measured during initial hardware testing)
* Cell is a multicore chip capable of massive floating point processing
* Cell is OS neutral and supports multiple operating systems simultaneously

"Today's disclosure of the Cell chip's breakthrough architectural design is a significant milestone in an ambitious project that began four years ago with the creation of the IBM, Sony and Toshiba design lab in Austin, Texas," said William Zeitler, senior vice president and group executive, IBM Systems and Technology Group. "Today we see the tangible results of our collaboration: an open, multi-core, microprocessor that portends a new era in graphics and multi-media performance."

"Today, we are very proud to share with you the first development of the Cell project, initiated with aspirations by the joint team of IBM, Sony Group and Toshiba in March 2001," said Ken Kutaragi, executive deputy president and COO, Sony Corporation, and president and Group CEO, Sony Computer Entertainment Inc. "With Cell opening a doorway, a new chapter in computer science is about to begin."

"We are proud that Cell, a revolutionary microprocessor with a brand new architecture that leapfrogs the performance of existing processors, has been created through a perfect synergy of IBM, Sony Group and Toshiba's capabilities and talented resources, "said Masashi Muromachi, corporate vice president of Toshiba Corporation and president & CEO of Toshiba's Semiconductor Company. "We are confident that Cell will provide major momentum for the progress of digital convergence, as a core device sustaining a whole spectrum of advanced information-rich broadband applications, from consumer electronics, home entertainment through various industrial systems."
 
I posted this article already in the other thread. Then I've posted it on GA and IGN got it from there ... I love the internet. ;)

Hmm.... 220 mm2 in 90 nm. Still quite costly, for a consumer product that is. Anybody any comments on the layout ? Looks like you can actually see the PPC core (= one ?) and these streaming processors (= 8 ??) on the die.

Only this die is a fake or ... where the h*ck are the bondpads ?

1 PPC core = 25 million transistors
L1 cache = 32kb for data , 32 kb for instructions
L2 cache = 512 kb about 25 million transistor

8 SPU with 128 kb(or 256kb) local storage, the LS size about twice than L1 cache ???? what is the truth???

edit:but in LS not cache logic , possible 256 kb
 
Sony would need at two of these to form PS3 CPU, if they are to even approach the 500 million transistors originally announced for PS3 CPU in 1999....

Wow...

I think we'll need Mr. www.chip-architect.com who is a master at figuring out chip architectures by measuring up dots and squares in die pictures ;-)

I was wrong... they decided to put the IO at both far ends.

Still, I think it's extremely costly for Sony to make a PS3 out of this. Assuming the first production runs (= this year ?) will be at 90 nm, they probably have to put 4 of these "babies" in there to make 1 Gflops happen. That's 4 x 70-80 Watts, no including the rest of box, not to forget the memories. Quick guess is that the BOM easily gets over 300 USD in silicon only. Add a harddrive, Blueray drive etc.
 
Now I'm sure Nvidia has nothing to do with hardware in PS3.....

1st - Developed jointly by IBM, Sony and Toshiba only.

2nd - "At first blush I think it's safe to say that it will be 10 to 20 times faster than the fastest graphics cards and processors," Doherty told New Scientist. "We think it is going to revolutionize computer science for entertainment and business." - http://www.newscientist.com/article.ns?id=dn6976

Cell developed by IBM, Sony and Toshiba is capable of running 10 to 20 times faster.... why should they need Nvidia? If Nvidia could duplicate their performance of current generation (6800), that's what I call - Miracle!

3rd - Just to dissipate any doubts - "Dubbed a "supercomputer on a chip" by its makers, Cell could have a major impact on high-end computing, such as scientific experiments and graphics rendering."


What is the role of Nvidia in the middle of this? Making T-shirts ?! :devilish:
 
Because they are not doing Software rendering in the PS3. CELL is a CPU, it will be used to process geometry, physics, AI, and other logic. It will not be used in games to render the final pixel, because pixel pipelines are still organized more efficiency to do this.

The quickest way to lower your effective throughput from the theoretically 250Gflops way down to mediocre is to make CELL render 1080p scenes in software.
