苹果芯片，全盘自研？

Core Viewpoint - Apple is transitioning to in-house modem chips, starting with the C1 modem in the iPhone 16e, aiming to replace Qualcomm and eventually control all network functionalities internally [1][3]. Group 1: C1 Modem Introduction - The C1 modem debuted in the iPhone 16e, focusing on efficiency but lacking support for 5G millimeter wave and all wavelengths of existing Qualcomm modems [3]. - The C1 modem is described as the most power-efficient modem on an iPhone, providing fast and reliable 5G connectivity [3]. Group 2: Future Modem Developments - The C2 modem, codenamed Ganymede, is expected to launch in the iPhone 18 series in 2026, featuring mmWave support and download speeds of 6 Gbps [3]. - The C3 modem, codenamed Prometheus, is planned for release with the iPhone 19 series in 2027, aiming to surpass Qualcomm's performance and support next-generation satellite networks [4]. Group 3: Network Chip Developments - Apple is also working on a new network chip, codenamed Proxima, to replace Broadcom's chips, expected to debut in HomePod mini and Apple TV updates later this year [6]. - This new chip will support Wi-Fi 6E and is anticipated to enhance connectivity between Apple devices while reducing costs [6]. Group 4: Integration Plans - After the modem transition, Apple is considering integrating its cellular modem into the main Apple Silicon chip, which could bring cost and efficiency benefits [7].
