Makes me wonder what the did spend it on...
Is it because it doesn't have an Apple logo on it?
The article is very vague. But seriously, they need to pay:
1) for a license. This is typically per-chip.
2) for the fab lots. This is typically per wafer start.
3) for engineers. A team of 50 is more than enough to design, verify, test, etc. these little chips. Let's call it 100. Average salary is, say $125K.
4) for EDA licenses. Even a huge company like AMD spent less than $20M on that.
5) for workstations, electricity, cubicles, etc.
Do the math. Like I said, it's never cost anyone $1B unless they also bought a fab (MicroUnity comes to mind).
I PM'd Fred Weber on facebook to ask him what he thinks, since the NYT article doesn't imply that he had anything to do with the $1B estimate.
