Yes, but a change from 60nm to 45nm isn't going to save them $100.... maybe $50 at best but that still isn't including the cost to change everything to the new process (changing moulds etc) |
Probably not, but remember a shrink from 65nm to 45nm results in a 50% reduction in chip area, hence twice the number of IC's per wafer, hence half the cost per unit (quite broad assumptions, but its a guestimate). So with the extra cost of 45nm fabrication, lets say each 45nm cell costs 60% of a 65nm one. So you are nearly halving the cost of two of the most expensive components in the PS3, even before you factor in all the other cost savings I mentioned previously. Sure it might cost $100million to redesign the masks for 45nm, but over the next 20 - 30 million PS3's, its wittles down to bugger all per unit, and insignificant compared to the savings involved.
