While Chipworks picked apart the iPhone 7 on sale in the USA and Europe, rival teardown gurus at iFixit used a Japanese version, which has a Qualcomm modem instead.
The iPhone 7 teardown by Chipworks revealed that the A10 processor is being single sourced from TSMC.
Wireless chipmaker Qorvo also has two chips inside the new iPhone, components manufactured in Hillsboro.
"Intel supplied not just one, but two RF transceivers, the baseband modem, and the (RF) power management IC", reads a blog post.
Apple never reveals specifics about the guts of its iPhones, and keeps its modem technology especially secret.
The fact that Apple is adding an Intel modem to the mix this time for phones sold in the U.S. means that not all iPhone 7s will work with all American carriers.
The iPhone 7 went on sale Friday and tech whizzes immediately went to work dissecting it to see what's inside. That's a big win for the world's largest chipmaker, which has been shut out of the iPhone and most other smartphones after famously arriving late to the mobile computing market. This is apparently a result of a modem supplier split between Intel and Qualcomm, with Intel's current chips unable to support CDMA networks due to licensing issues. iPhone 7 and 7 Plus models with Qualcomm modems can support both GSM and CDMA networks. Its not known (but likely) that the CDMA variants connecting to Sprint or Verizon stuck to Qualcomm for their modems.
The teardown confirmation has also solidified earlier rumors of Apple going for multiple modem vendors.
