Rocking an iPhone 5S and think you're 'sticking it to Samsung' when you use it? Think again. The South Korean giant, and main competitor to Apple, is the company who is making the A7 processor inside each and every iPhone 5S.
Chipworks says that it found design and manufacturing processes on the A7 chip that match up with Samsung-built chips such as the Samsung Exynos Application processor that is baked into the Galaxy S4 smartphone. Samsung will also reportedly supply Apple with components for its upcoming second generation iPad mini tablet.
So while they may be competitors, they still require each other to make money. Apple wouldn't have as many iPhone 5S units if it weren't for Samsung, and Samsung wouldn't be racking in billions manufacturing hardware for Apple.
