Does anyone have any data that they can share on the following -- as a company, if I licensed the latest generation ARM processor (e.g., Cortex-A15) and then factored in any additional design and manufacturing costs (e.g., via a foundry), what would be the total cost advantage of using an ARM chip versus a comparable Intel chip (e.g., Atom)? Thanks!
