Apple making its own chips starting with the A4
Even though this morning's presentation had Apple calling themselves the "largest mobile device company" in the world, apparently they're in the processor business now, too. The just-announced iPad doesn't carry any special Intel or Nvidia CPU -- it's a homecooked 1GHz chip called the Apple A4. Apple says it's designed for high performance and low power, which is probably how they got that crazy 10 hour battery life and one month (!) standby life. We guess that PA Semi acquisition was a good idea.
We've been hearing for a while that Apple was picking up chip designers and hiring specialists for chipmaking, and it looks like the A4 is the first release (fourth produced?) product of all of that. It'll be interesting to see how their first major foray into silicon works out.
