اكثر كلام المقالة تتمحور حول معالج الخلية ومدى الاستفادة منه في home servers وكلام عن مسألة توحيد الصيغة بين سوني وتوشيبا وكالعادة قال بأن البلو- راي راح يكون هو الخيار الوحيد للبلاي ستيشن3 بسبب موعد الصدور وماشابه...وكمان تطرق لأمكانية زيادة سرعة المعالج الى4GHz لو كانو يفكرون في تسويقه واستخدامه بــ high-end computer وذكر سبب عدم استخدام هذي السرعة في معالج لبلاي ستيشن3 وألخ

Kutaragi stated earlier that although the Cell microprocessor comes with eight synergistic processor elements (SPEs) for multicore processing, the chip only uses seven of them. Kutaragi explained that ignoring one SPE as a redundancy will improve the chip's production yield and allow costs to drop dramatically. In other words, Sony can ship a Cell chip with one defective SPE (out of its eight) as a working product, since the chip only uses seven SPEs to begin with.
"This is the ultimate aesthetic. The number of SPEs we equip to the Cell and how many we will actually use are two different things. I wanted to adopt the idea of 'redundancy' to the development of semiconductors. Logic LSIs, excluding memory chips, are considered defective and unshippable if just one transistor or line doesn't work. If the Cell's final chip dimension is about 200 square millimeters, making one without any defects is extremely difficult. We can't reach our anticipated production yield with that. Of course, we'll take various measures to lower the defect density, but that won't be enough. But by considering one or two SPEs as a redundancy from the very beginning, we can still use a Cell chip even if it's partially defective," Kutaragi said, who also revealed that a similar scheme would also be used for the PlayStation 3's RSX graphics processor.
"An interesting question is what will be done with the Cell chips that only have six working SPEs," continued Kutaragi. "We won't use it for the PS3, of course. Rather, I'm seriously thinking about using two of these chips to create a home server. Home servers have less of a constraint in case size and board dimension when compared to the PS3, and we can make enough space for two Cell chips. That will make it a product with a total of 12 SPEs. This is possible with the Cell since it can use as many SPEs as it needs. And this will bring a use to Cell chips that aren't fit for the PS3."
Kutaragi went on to explain that one of the reasons why the Cell chip for the PS3 was announced to run at 3.2GHz at E3 was due to heat issues. Back when the chip was first announced at the International Solid-State Circuits Conference (ISSCC), its spec said that the chip could run at 4GHz. "We could create a 4GHz Cell if we were aiming to sell it for a high-end computer," Kutaragi said. "There's also the issue of heat. We might have had to create the PS3 with a bigger body if we adopted a 4GHz chip for it."
Kutaragi also talked about his decision to adopt Blu-ray for the PlayStation 3 rather than wait a bit longer to see if the Blu-ray and HD-DVD factions would come to a final conclusion on a unified disc standard. "E3 was the last chance," Kutaragi said. "The PS3 is the console of the future, so I wanted an extreme amount of capacity. But for that, we need cutting-edge technology, and not technology that is currently available. My suggestion was to come to an agreement with a physical format that is as close to [the Blu-ray's] 0.1mm as possible. But the PS3 launches in spring 2006. If we had continued to wait for a unified standard, we wouldn't be able to release the PS3. We no longer have any more time. It's game over."
