MediaTek will supply modem chips for Apple Watch models from next year, replacing Intel, Bloomberg reported on Wednesday. Why it matters: The use of MediaTek’s modem chips in Apple Watch is expected to help MediaTek growth. The satellite feature, enabling message-sending without cellular or internet connections, will debut in next year’s Apple Watch Ultra. The shift to using MediaTek’s modem chips in the Apple Watch will bring support for 5G Redcap. During this quarter, MediaTek launched its new flagship chip, the Dimensity 9400, which utilizes TSMC’s second-generation 3nm process technology.
