Itanium - I'm sure their yield is good for a 421mm2 die.


Perhaps you didn't understand my comment about critical
area. It is entirely in the realm of the possibility that the
421 mm2 McKinley could yield better (i.e. higher percentage
of functional die after repair) than the 217 mm2 Willamette
made in the same process. Look at microphotographs or
die plots of both devices and the reason for this is staring
you right in the face.

That is not to claim that McKinley yielded better in practice -
the Willamette was made in >1000x higher quantities and that
has an impact of its own. But to say that I2 has manufacturab-
ility issues because of its size is simply not true.
