>> Intel is up to around $6B/year in R&D spending, so at 100Mu/year that is almost $60/unit in R&D costs.
Alan, Thanks for supplying context. However, I don't know if you meant that Intel produces only 100m units per year. As far as PC processors, Intel sells approx 200m units per year (50m or more per quarter). So the R&D $$/unit are approx $30/ea for Intel. (and $50/unit for AMD).
