Okay that's a bit much but I can already see the misinterpretations that will start flying around.

According to GameSpot Kutaragi was recently interviewed about the PS3 cell processor:
Quote
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.

Interesting stuff indeed.  Flame on!

Nvidia's already been doing the same thing on the 6800's.  In fact, some people have found ways to unlock the unused core.

Nothing surprising. Thats pretty much common practice with CPUs and graphics chips.

Yeah, I tried this last fall when I got my Dell w/ 6800, but it immediately produced screen artifacts in my case.

Is it possible to learn this power?

Well... you could click on the link embedded in "ways to unlock" in the quote above.

These engineers seriously need to get laid... synergistic processor elements?
