Many tech bloggers also found out that the Samsung A9 chip has lower battery life and also slightly lower performance—although I would say that it does not really bother the iPhone much in real world performance.
Just recently, two separate reports have surfaced that indicate that Apple has seemingly chosen to make TSMC the sole producer of the A10 processor chips slated to be released in the iPhone 7.
The A10 processor chip is still under development, but TSMC’s integration of a fan-out wafer-level packaging technology into their manufacturing process seems to have played a key role in Apple’s decision to award TSMC sole production rights.
The InFO WLP manufacturing technology is able to deliver better electrical component integration in a singular package, and iPhone In Canada reports that it can lead to reducing power usage for mobile devices by supporting higher-width memory buses necessary for maximizing efficiency.
Taiwan’s Commercial Times, via EE Times, first reported the news and KGI Securities analyst Ming-Chi Kuo later released a research report that confirmed Commercial Timesassertion that Apple has awarded TSMC sole production rights for the iPhone 7’s A10 processor chip.
Regarding Chipgate, while the A9 processor chips created by Samsung and TSMC were supposed to be identical, it was later revealed that Samsung’s version of the A9 processor chip was smaller than TSMC’s version, by 96-mm2 to TSMC’s 104.5-mm2. Theoretically, Samsung’s chip was supposed to be more power efficient but in real world tests, TSMC wins by far.
