如果您希望可以时常见面,欢迎标星收藏哦~ 来源:内容来自半导体行业观察综合 ,谢谢。 苹果自推动Apple silicon长期计画以来持续扩张自行研发芯片的路线,其中备受外界讨论多时耕 耘多年5G Modem芯片C1先前已正式浮上台面,一般预料持续由伙伴台积电(2330)操刀,究竟 苹果自研芯片效益如何,研究机构最新分析也解密。 iPhone 调制解调器的演变 法人则分析,若按照苹果iPhone 16e 出货规模今年可达到2200万支来看,至少可省下2.2亿美元。 若后续更多iPhone导入,按照一年2亿支规模来看,基带芯片初估就可省下成本达20亿美元(相当 于新台币650亿元),相当可观。但苹果和高通还有合约限制,业界预期苹果自研新款芯片将采逐 步推进导入手机。 苹果是台积电大客户,也是台积电先进制程最大出海口。台积电7纳米以下先进制程营收占比已突 破七成,达到73%,今年首季7纳米出货占15%,5纳米36%,3纳米为22%,先进制程持续扮演获 利的引擎。台积电加码美国千亿美元投资,预估专案投资到位后,估三成2纳米以下先进制程产能 将在亚利桑那厂生产,支援客户包含苹果、英伟达、超微、高通与博通等需求。 深挖 ...

Core Viewpoint - The article discusses the evolution of modem chips in iPhones, highlighting Apple's transition from Qualcomm to its own Apple C1 modem for the iPhone 16e, and the implications for the semiconductor industry [1][3][18]. Group 1: Modem Chip Evolution - Apple has been using Qualcomm's modem chips since the iPhone 12, with the upcoming iPhone 16/16 Pro set to use Qualcomm's Snapdragon X71 modem [3][18]. - The iPhone 16e, scheduled for release in February 2025, will feature Apple's own 5G modem, the Apple C1, marking a significant shift in Apple's supply chain strategy [3][18]. Group 2: Technical Specifications - The Apple C1 modem is developed from technology acquired from Intel's modem division, which Apple purchased in 2019 [11][14]. - The C1 modem utilizes a 4nm manufacturing process, which is more advanced than the 5nm process used by Qualcomm for its modems [19][20]. Group 3: Internal Structure and Components - The internal structure of the iPhone 16e includes a unique configuration with three Apple-branded chips, including a digital baseband, RF transceiver, and power management IC [8][19]. - The iPhone 16e's camera system and battery design are optimized for performance, with a single camera unit allowing for a larger battery capacity [5][6]. Group 4: Industry Implications - Apple's move to develop its own modem chips indicates a trend towards vertical integration in the semiconductor industry, potentially impacting suppliers like Qualcomm and MediaTek [1][3][18]. - The article suggests that Apple is likely to continue developing its modem technology, with future iterations (C2 and C3) expected in subsequent iPhone models [18].
