Intel has started manufacturing its XMM 7560 LTE modem, the next-generation chips that will go into the 2018 iPhone series. This is the first chip that is completely an in-house job for Intel and it is also the company’s first to support GSM and CDMA. Prior to this, TSMC made chips for Intel and all CDMA iPhones were dependent on Qualcomm chips due to the former modem’s inability to support CDMA. However, the tables have turned, with Apple now able to rely less and less on the Snapdragon chipset manufacturer.

Apple had originally planned to place all its modem orders with Intel as it was in a long and tiresome legal dispute with Qualcomm. However, the plans couldn’t go through as Intel ran into some equality issues during the production process. To resolve the issue of Intel’s lower yields, Apple will need to source modems from Qualcomm even now.
