On Wednesday (February 19), Apple announced the upcoming launch of its "budget-friendly" iPhone 16e smartphone model. The Cupertino, California-based company has refreshed its entry level product tier—starting at $599—with modernized internals. Apple's new design houses an A18 chipset, as well as their much-discussed debut modem design. The C1 is a custom 5G part; fully developed in-house. Previously, modern iPhone product ranges have been fitted with Qualcomm 5G modems. As expected, Apple contracted with TSMC for the production of A18 and C1 silicon—the A-type SoC is based on a 3 nm process node (TSMC N3E). Their proprietary modem baseband design utilizes 4 mm, while the receiver uses a 7 nm process—according to insiders.

Taiwan's Commercial Times reckons that TSMC will be the "biggest beneficiary" from the aforementioned agreement with Apple. Ctee TW's latest report cites industry analysis; soothsayers estimate annual shipments reaching roughly 22 million units annually. Additional whispers suggest that the C1 modem will turn up in non-iPhone devices—namely next-gen Watches and iPads, by next year. The report also mentions that upcoming Mac products are slated for C1 upgrades. Further leaks have linked project "Ganymede" to a "C2" custom 5G modem design—inside sources believe that a 3 nm TSMC process is on the cards. Another codename—"Prometheus"—was leaked by insiders; possibly referencing a future "C3" model.
