Teardowns of the iPhone 6s and 6s Plus have revealed that two different manufacturers, Samsung and TSMC, produce the Apple A9, each on their respective process node. An iOS developer, Hiraku Wang developed an app that reveals whether the iPhone in question has a processor manufactured by TSMC or Samsung. The ratio is somewhere around 6:4 for TSMC:Samsung chips. Hiraku’s app only determines whether an iPhone has a TSMC or Samsung chip, but it does not reveal whether there are any performance differences. But a Chinese site has tested two pink (or Rose Gold, if you so please) iPhone 6s 64GBs, both updated to iOS 9.0.2 and ran Antutu benchmark on both devices, and the difference is quite noticeable.


CPU difference

As you can see, the TSMC’s chip is codenamed s8003 and is manufactured on their 16nm process, while the Samsung one is codenamed s8000 and is based on their 14nm process.


benchmark difference

The Antutu benchmarks were ran 12 times, and this is the 6th run’s results. A difference of 1354 equates to a difference of around 2%. Not much, but the Samsung does score less than the TSMC consistently according to their testing, which could mean that the TSMC chips does actually perform better than Samsung chips.


temperature difference

By the 11th run, a temperature difference is also spotted. 40.5°C from iPhone 6s with the Samsung chip against 37.4°C on the iPhone 6s with the TSMC processor.


Battery difference

The last difference that was spotted is a difference in terms of battery remaining after the 12th run. The iPhone 6s with the Samsung chip was left with 71% while the one with the TSMC chip was left with 77%, a 6% difference. This doesn’t necessarily reflect on higher power consumption of the Samsung chip, since Apple also sources a lot of its other components from other OEMs, most notably here is the screen, as a different screen may result in different power consumption figures.

Go ahead to the source link (in Chinese) to look at the consistent difference observed by the tester between the iPhone 6s with different processors.

Pokdepinion: This piece of news is quite interesting. It shatters the assumption that smaller = better when it comes to process nodes. While the difference in performance, heat production, power consumption may not be massive, consumers who want the best of the best may now have to find out what processor is inside a iPhone 6s they intend to get before paying for it. Benchmarks are benchmarks, however, and the user experience might not be affected at all. With the iPhone 6s arriving in Malaysia on the 16th of October, what do you think? Does this difference in terms of processor specification cause you to reconsider getting one?
