Even before the launch of the iPhone 6s and 6s Plus, it was speculated that their main processors could be manufactured by Samsung and TSMC. Gossip turned out to be true, and after the launch of new products discovered a surprising thing, namely the processors of both companies are different in size.
This information was disclosed by Chipworks, which has published the size of both the APL 0899 Samsung and APL1022 from TSMC on its backline. As you can see in the attached image, the A9 processor manufactured by TSMC is about 10 percent larger than the Samsung model. What is the difference? Probably related to the production process, which can make the chip of the Korean corporation more efficient than the rival system.
Apple has in the past used components from various manufacturers in its devices, which led to the fact that some components were more efficient than rival products. That was the case with MacBooks where SSDs from Samsung and Toshiba were installed. As you may have guessed, the first manufacturer’s drives were much faster. The same was true with the screens that the company Cupertino ordered simultaneously with Samsung and LG Display. Here too, the advantage of Samsung’s products was undeniable.
