Turns out Apple's A7 processor featured inside the iPhone 5s was built by Samsung

As so often is the case during Apple's new device announcements, Tim Cook n' friends was curiously mum on details about their all new A7 chip found inside the iPhone 5s. To be fair, they told us it was powerful, and according to recent benchmarks performed on the device, they're right. What they didn't tell anyone is where the new chip came from. Ironically, the A7 is manufactured by none other than smartphone rival Samsung.
Chipworks in collaboration with iFixit made the startling revelation after ripping the device apart and examining each component piece by piece. What they found was a 64-bit A7 built using Samsung's new 28nm process.
