Guess who's making the advanced A7 processor running Apple's iPhone 5S?

It's none other than bitter mobile rival Samsung.
 
A teardown of the newest Apple smartphone by Chipworks.com showed the new 64-bit A7, a system-on-a-chip, was fabricated at Samsung's foundry.
 
"We have confirmed through early analysis that the device is fabricated at Samsung’s Foundry and have confirmed the process type and node," the report said.
 
The site also posted an electron microscope image of a cross-section of a group of transistors in the A6 (APL0598) chip, fabbed in the Samsung 32-nm high-k-metal gate (HKMG) process.
 
Also, its analysis of the A7 (APL0698) showed that the processor is made on the same process as the new Samsung Exynos 5410, the 28-nm HKMG process.
 
The iPhone also sports a Qualcomm MDM9615M 4G LTE modem that uses a Samsung DRAM to retain carrier specific information and a Samsung-fabricated LTE baseband processor.
 
Chipworks also noted a new M7 co-processor, which helps reduce power consumption by collecting and processing accelerometer, gyroscope and compass data.
 
"The M7 is dedicated to processing and translating the inputs provided to it by the discrete sensors; the gyroscope, accelerometer and electro magnetic compass mounted throughout the main printed circuit board," it adds.
 
On the other hand, it bared that the iSight camera indicates a Sony sensor.
 
"Internal shots revealed the A7 to be made by Samsung," said iFixit, which has been working hand in hand with Chipworks to tear down the iPhone 5S.
