Xbox 720 & PS4 codenames revealed, Microsoft’s ‘Oban’ chip still delayed – rumour

[JEMC]

@crissindahouse: no need to correct anything because all you've said is true.

I would only add that Microsoft or any other client can make a deal based either on waffers or chips, meaning that they have to pay for the whole waffer or only for the viable chips.

In the first and more common case, if yields are low then each chip costs more (cost of chip = cost waffer/nº of viable chips). It doesn't affect the quality of the chips.

Very useful pic, btw.
