iPhone teardown. Guess what? According to Chipworks, that's the Apple A4 microprocessor fabricated by Samsung and the presumed work of Apple's acquired PA Semi and Intrinsity engineers. The "APL0398" text is also the same as that found on the iPad's speedy and power sipping A4 system-on-chip. The other markings differ however. What that means isn't entirely clear yet but we're digging."
This new processor is the same one that is located in the iPad. Will the new iPhone be as good as the iPad? We will just have to wait and see. This is a very pleasant surprise!
