Apple's iPhone SE4 and its In-House Modem: Performance Gap and Advantages Compared to Qualcomm's X75

A recent report by South Korean media outlet donga suggests that Apple's first self-designed modem, slated for the iPhone SE4, may not match the performance of Qualcomm's flagship Snapdragon X75. This has sparked industry-wide discussion regarding Apple's in-house chip strategy. This analysis, drawing upon the report, delves into the performance, features, and potential advantages of Apple's self-developed modem.

The report highlights a significant drawback: the lack of mmWave 5G support. mmWave 5G, known for its high speeds and low latency, is a crucial aspect of 5G network development. The absence of mmWave support in Apple's modem will undoubtedly limit its potential network speeds. In contrast, the Qualcomm Snapdragon X75 fully supports mmWave 5G, offering faster download and upload speeds.

Furthermore, Apple's modem may also fall short of the Qualcomm X75 in carrier aggregation capabilities. Carrier aggregation combines signals from multiple frequency bands to increase bandwidth and speed. The Qualcomm X75 boasts mature carrier aggregation, providing stable high-speed connections even in complex network environments. Apple's modem, reportedly, currently lags in this area, directly impacting the iPhone SE4's network performance.

Multiple sources indicate a noticeable gap in upload and download speeds between the iPhone SE4 (with Apple's modem) and the iPhone 16 series (equipped with the Qualcomm X75) in real-world network speed tests. This difference stems not only from the lack of mmWave 5G but also from the disparity in carrier aggregation capabilities. This could be a significant factor for users who prioritize network speed.

However, Apple's self-designed modem isn't without its advantages. The report emphasizes its dual SIM functionality and deep integration with Apple's own processors. Dual SIM is now a standard feature, and its inclusion caters to a wider range of user needs. More importantly, the deep integration with Apple's A-series processors promises improved energy efficiency, extended battery life, and reduced power consumption a major draw for users valuing battery performance.

Apple's decision to test its first-generation modem on the iPhone SE4 is also noteworthy. The iPhone SE series is known for its budget-friendly pricing. Launching the modem on this series mitigates testing costs and risks while providing valuable experience for future implementation in higher-end models.

In the long term, the biggest advantage of Apple's in-house modem is reduced reliance on Qualcomm, thus saving on licensing fees. Apple has historically paid substantial sums to Qualcomm for patent licensing. Developing its own modem significantly cuts these costs, boosting profit margins a crucial aspect of Apple's long-term strategy.

In conclusion, Apple's first self-designed modem exhibits a performance gap compared to the Qualcomm X75, particularly in mmWave 5G and carrier aggregation. However, its dual SIM capability and the energy efficiency gains from deep integration with Apple's processors offer unique advantages. The choice of the iPhone SE4 for testing reflects a cautious, measured development approach and a long-term cost-reduction strategy. Future performance improvements will depend on Apple's technological advancements and market acceptance of its performance-price ratio. Ultimately, its success hinges on the speed of technological improvements and the market's tolerance for the performance-price trade-off.
