IBM Claims 10% - 20% Yield “Lucky” for the Playstation 3 Cell Processor
 

In an attempt to offer the most powerful game console on the planet and ensure that the PlayStation 3 games are unique, Sony decided to put a very advanced Cell processor inside the machine. But now it transpires that to produce the chip in large quantities is not that easy.

At a cost of $230 with 10-20% yield = >$1150 each ..... at is at cost.

In the last paragraph, it sounds like the $230 figure is including the cost of dead/not-fully-functional chips, because I don't think even a huge corporation like Sony has deep enough pockets to cope with a loss like that on every console. But who knows, maybe they see Cell as worth the massive loss upfront?
