AMD fabs are cranking day and night
FAB36 is fully equipped for K10 production. Those $200 Barcelona CPUs make people happy - except Intelers.
Intel's yield is so low, they can't make native quad core due to high defect density. Intel admits this. It has to wait for 45nm to get reasonable quad core output. Currently, Intel quads are just double cheese burger design -- zero originality. Intel CTO, Dr. Rattner, feels ashamed by Intel engineering. A couple of months ago, a top Intel CPU architect commented that Barcelona is too advanced to be feasible. His logic was that since K10 is too advanced even for Intel, AMD cannot possibly deliver it.
AMD's K10 yield is above 90%, due to the wonders of APM.
