Not necessarily. If 65nm has a much higher likelihood of delays, poor yields, etc., i.e. higher risks, then the conclusion is unclear, and going with 90nm first might make sense.
which conclusion was wrong? I said AMD would not start-up fab36 on 90nm... and I said if for some reason they decided to do that the best way would be to copy the IBM 90nm process. not sure where you are coming from on that statement. --Alan
