How to check whether your new iPhone 6s / 6s Plus comes with Samsung or TSMC-made Apple A9


The new Apple iPhone 6s and iPhone 6s Plus come with the brand new Apple A9 system chip that is a huge improvement over the A8 used in the iPhone 6.

But did you know that - unlike before - this time, the Apple A9 is not one chip. With the transition to a new and more efficient manufacturing method, Apple had to double source the Apple A9 from Samsung and TSMC. And since the actual manufacturing technology at the two companies differ - both use FinFETs, but Samsung makes its chips on a 14nm process, while TSMC uses a 16nm manufacturing node. In fact, while the Samsung-made Apple A9 occupies a die surface of 96mm2, the one made by TSMC is slightly larger, at 104.5mm2. We have also seen that there is a difference in the actual performance of the two.

So how do you check whether your new iPhone 6s has a Samsung or a TSMC version of the Apple A9 chip?

Luckily, this is not a hard task. You can download one of the many free apps that report the model number for your new iPhone, like the Lirum Device Info app right below.


Once you download it, you just open it and scroll down to the 'Storage and Model Information' section. What you are looking for here is the 'Model' number. And here is how to decipher the meaning of the model number:

Apple iPhone 6s:


N71AP - Apple A9 made by Samsung
N71MAP - Apple A9 made by TSMC

Apple iPhone 6s Plus:


N66AP - Apple A9 made by Samsung
N66MAP - Apple A9 made by TSMC

Right below you can see that we have the N71AP, an iPhone 6s with a Samsung-made Apple A9. What's yours?

If I'm a casual iphone user, why would I want to worry about these things since I pay big money for a product that I expect will run smoothly? Unless apple is ripping me off right?

Obviously, you don't need to worry. This is just for those who are curious to learn about the chip inside their phone. No need to look for drama in every single detail, we've posted similar articles about the difference between Samsung Exynos and Qualcomm Snapdragon chips in Galaxy phones.

There is 1/16 chance you will get the best iphone: 1. Samsung 14 + mlc + LG ips + Samsung 2GB 2 Samsung 14 + mlc + LG ips + Hynix 2GB . 7. Samsung 14 + tlc + Sharp ips + Hynix 2GB . 10. tsmc 16 +mlc + LG ips +Samsung 2GB . 16. tsmc 16 + tlc + sharp ips + hynix 2GB If tsmc got all the best components and samsung got all the worst, tsmc wins but, if they had same ones, samsung wins typical chinese tactic brainwashing people saying that 16 is better than 14 even tho they can't explain. they will next say their 14 is better than 10 for unknown reasons

Lol my work phone is the Samsung one. Oh well, at least I have the 14nm and smaller chip. I'd actually take that over the 7% extra battery.

Mine also has the Samsung chip idk I haven't had any issues and my battery lasts all day so what happens if we return our phones and get the same chip again.

You could probably ask them for the model numbers listed in the phonearena article on differentiating between the Samsung and TSMC parts.

Lol Samsung really killed it this year. The GS6 and Note 5 crushed everything easily, gear S2 is flat out brilliant and the only watch that can really pass off as a real watch vs an oversized computer on your wrist. And now they created a lot of isheep tears by f**king up the A9. Great Job Samsung. Spot on year. Now don't screw it up by releasing and hyping that Galaxy View thing unless it's actually on par with the GS6/Note5/Gear S2.

TSMC > SAMSUNG on chip manufacturing. It is that simple.

Yet Samsung one is smaller with same perfomance lol

So Chipworks was the first to reveal through the their teardowns the availability of two A9 chips and said they will do a performance review between the two. But two weeks later there is still no review from Chipworks, think someone has silenced them (hint hint, look east)

So Samsung has an advantage with 14nm but they still get beaten by TSMC who is at a disadvantage?

TSMC are better with the architecture Apple use. Also samsung 14nm is not thats good with overheating ( Samsung S6 throttle up to 40% btw )

OK coool

1. Shocky unregistered

Makes no difference which your phone using so what's the point in checking this? You came to a conclusion based on a single sample from each, it was meaningless. Stop spreading BS.

3. TyrionLannister unregistered

Actually many Youtubers checked and found the same. The performance is the same on both but the TSMC one is about 20-30% better at battery management. Samsung screwed it up big time; or they did it on purpose. I don't know. But one thing is clear. I would want the TSMC made iPhone 6S.

You really think Samsung would do it on purpose? Really? That's how Bullsh!t rumors get started with idiots saying stupid crap they cant prove, to put questions in peoples's heads. Apple had at least a year to test Samsung's chipset. If they had an issue with it, they would have worked with Samsung to deal with it, if they saw it as an issue.

Nope as TSMC was unable to fullfill all the order and Apple had no other choice to go for the Shamesung crap soc thats overheat.

of all the companies in the world that makes chips they go the the "enemy" company, thats stupid thinking right there, they worked with samsung to ensure a great chip thats the truth, by the way it is tsmc who should be worried since theire technology is not up to par with that of apple.
