At the International Solid State Circuits Conference (ISSCC) today, the PlayStation 3-powering Cell processor developed jointly by IBM, Sony and Toshiba was finally shown to an expectant crowd.
The unveiling has been a long time coming, with most estimates putting Cell development around 12 months behind schedule.
And down to business. The first point of note is that the PlayStation 3, arguably the Cell’s flagship host, will receive a prototype of the processor, hinting at Sony’s strong desire to expedite the launch of its next home console. The version to power the PS3 will have a 221mm² die and use 234 million transistors, made using ‘Holy Grail’ 90nm process technology.
It will contain eight 64-bit floating point processors, referred to as synergistic processor elements (SPEs), running along side a 64-bit Power processor capable of running two threads. The SPEs take will 128-bit operands and split them into four 32-bit words. Up to 128 operands can be stored in the Cell register file.
"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."
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 plant, later this year.

So we are left with the question, now that the Cell is more than a vapourware dream (various dies were shown at the event as pictured) where does this leave the PlayStation 3 and its launch? SPOnG considers it unlikely that the East Fishkill will manufacture PlayStation 3 chips, with that being left to Sony’s Nagasaki facility. Production there, as outlined above, commences at an unspecificed point this year. So essentially, the PlayStation 3 could be on shelves within 2005 though of course, that’s wildly unlikely.
What is more likely is first-generation hardware dev kits shipping in time for Christmas, replacing the high-end PC with port guidelines adopted by studios across the world. SPOnG then estimates that Sony could realistically see a PlayStation 3 launch in time for Easter 2006. Although software would be very thin on the ground, SCEI has never seen this as an obstacle to launching a home machine. Option two would be to launch the PS3 late 2006 in time for the holiday period, though with Microsoft already racking up a year of Xbox 2 by then, timeframes may have to overpower a credible launch line-up.
And of course, Sony still has its Dreamcast-killing trick up its sleeve. The dark horse of ‘wait and see’ which worked with lethal efficiency at the dawn of the current generation of platforms.
Expect updates on all things PlayStation 3, right here, as they break.
