"CPU Identifier" to check whether the A9 chip of "iPhone 6s / 6s Plus" is TSMC or Samsung

In "iPhone 6s / 6s Plus", because Apple is building both hardware and softwareAwesome performanceAlthough it is possible to experience, it supports the third generation Apple chip which has desktop PC level 64 bit architecture "A9 chip"is. This A9 chip is manufactured by Taiwanese semiconductor manufacturer TSMC and two companies of Samsung, but in order to ascertain which handset the chip manufactured by the manufacturer of the iPhone 6s / 6s Plus is on hand The tool "CPU Identifier"Has been released.

"Engineering consultancy company providing patent support and technical analysis services"Chipworks"Apple's" iPhone 6s / 6s Plus "reverse engineeringWe discovered that there are two types of A9 chips mounted on them, one manufactured by TSMC 16 nm process and one manufactured by Samsung 14 nm process.

The following pictures are Samsung's A9 chip "APL 0898 (left)" published by Chipworks and AMC chip "APL 1022 (right)" made by TSMC. For die size, Samsung's APL 0898 is 96 square mm and TSMC's APL 1022 is 104.5 square mm.


Samsung's APL 0898 is slightly more compact if you overlap two.


About this, Chipworks says, "It was a very surprising finding two different processors on one terminal called iPhone 6s." Also, except for the case that "small die size can not be obtained in sufficient amount", there are few reasons why it is necessary to have a chip of large die size in terms of both cost and performance, both comments. In addition, Chipworks' benchmark test states that even if the same SoC design is run in two different processes, either one will not produce better results.

So there are two types of A9 chip, one made by TSMC and one made by Samsung, so it is good to develop a jailbreak application for iOS@ HirakujiraIf you use the "CPU Identifier" that is open to you, you can check with one shot which A9 chip made by which manufacturer is installed. Since "CPU Identifier" is not an Apple official toolPlease give me the task ahead from here on your own risk.

To use "CPU Identifier", open the above URL on either iPhone 6s / 6s Plus terminal and tap "Install". The installation page says, "'CPU Identifier' does not collect private information other than CPU and terminal model information '."


Tap "Install".


Then the following icon is added to the home screen, so when you tap it ...


The application does not work because "an untrusted enterprise developer". To activate the application, first tap "Cancel" ......


Tap "Settings" on the home screen.


Tap "General".


Tap "Profile".


Tap "ShenZhen Shixunhulian Technology ..." in Enterprise APP.


Then confirm that there is "CPU Identifier" and then tap "Shen Zhen Shixunhulian Technology Co., Ltd." ... once again.


Tap "Trust".


If "Delete App" is displayed, it is ready.


Tap "CPU Identifier" again from the home screen ... ...


Instantly we will decide which one is the A9 chip. I used iPhone 6s Plus for diagnosis, but it seems that TSMC A9 chip is loaded.


The information on the A9 chip collected by "CPU Identifier" is summarized as follows.

Approximately 80% of users who examined iPhone 6s A9 chip with "CPU Identifier" seems to be made by TSMC.


Conversely, iPhone 6s Plus makes Samsung made a little more.


Overall it seems that A6 chips made by TSMC are increasing at a ratio of roughly 6: 4.


On the iPhone 6s it seems that the number of A9 chips made by Samsung is small, so if you see the letter "Samsung" after diagnosis, you can boast that "My A9 chip is made by Samsung!" Around ... ... .
