Images Suggest Some iPhone 15 Models Could Feature Thunderbolt Data Transfer Speeds
Some iPhone 15 models will be equipped with a Thunderbolt/USB 4 retimer chip for high-speed data transfer, according to ChargerLab.
Following last week's leak of alleged images of the iPhone 15's USB-C port components, ChargerLab has seen further images of the parts and believes that they show an integrated circuit (IC) for Thunderbolt data transfer speeds.
The IC, known as a retimer, rebuilds signals and mitigates jitter. It augments signal transmission stability for high-capacity data ports and extends transmission ranges. Such chips are seen in other Thunderbolt/USB 4 devices, and ChargerLab believes it is clearly identifiable on the iPhone 15's USB-C components.
All four iPhone 15 models are expected to feature USB-C instead of Lightning. The iPhone 15 Pro models with USB-C ports are expected to support higher-speed data transfers, likely up to Thunderbolt speeds, while the standard iPhone 15 models will likely continue to feature USB 2.0 speeds – the same as Lightning. For comparison, the iPad Pro features a Thunderbolt port for transfer speeds up to 40 Gbps, while the entry-level iPad's USB-C port is limited to just 480 Mbps.
