The contra-revenue per Bay Trail-v0 is $20, and for Bay Trail-Entry it is about $10.
Wrong. It's not a fixed value. It differs from customer to customer. It's based on the delta in BOM costs, in order to level the playing field. And not just the components in the Bay Trail system, but the components in the alternative system that Bay Trail is competing against. Every OEM's BOM will be different, and so will the deltas vs. the equivalent ARM based system.
