  • So what is a package? You're looking at one.

  • This is a cross-section of the iPhone's ARM processor + RAM package. Click here to see it in its full, 2854x313 glory.

  • The processor itself is the center rectangle. The silver circles underneath it are solder balls.

  • The two rectangles above the processor are RAM dies. They are offset from each other to make room for the wirebonds, which you can't see in this shot.

  • Having the RAM so close to the processor both reduces latency—making RAM access faster—and cuts power consumption, helping your battery last longer.
