The latest data I have seen on this was: hammer $82 Barton $46 P4EE $59 P4 $42 all on 130nm, data from microprocessor reports. I suspect the package and test cost for hammer is only 20% or so greater than barton, but I do believe the die cost is probably 3x. --Alan
I guess the follow-up question would be is the delta in the ASP for the K8 greater than the delta in the COGS. I assume your 2x - 2.5x is somwhere between $25-$50. Given that AMD is not production limited, it would seem like it makes sense to maximize profits.
