Fast Data Transfer with the iPhone 15: Thunderbolt/USB 4 Retimer Chip in Focus
- Some models of the iPhone 15 may be equipped with a Thunderbolt/USB 4 retimer chip for fast data transfer.
- The retimer chip improves signal transmission stability and extends the transmission range.
- The Pro models of the iPhone 15 are expected to support higher data transfer speeds, while the standard models will continue to have USB 2.0 speeds.
A new report from ChargerLab suggests that some models of the upcoming iPhone 15 could be equipped with a Thunderbolt/USB 4 retimer chip for fast data transfer. After leaked images of the possible USB-C port of the iPhone 15 last week, ChargerLab has seen further images of the components and believes that they show an integrated circuit (IC) for Thunderbolt data transfer speeds. The retimer chip improves signal transmission stability and extends the transmission range. This chip can be found in other Thunderbolt/USB 4 devices, and ChargerLab believes that it is clearly identifiable on the USB-C components of the iPhone 15. While all four models of the iPhone 15 are expected to use USB-C instead of Lightning, the Pro models are likely to support higher data transfer speeds, possibly up to Thunderbolt speeds. The standard models are expected to continue to have USB 2.0 speeds, the same as Lightning. For comparison, the iPad Pro has a Thunderbolt port for transfer speeds of up to 40 Gbps, while the entry-level iPad's USB-C port is limited to just 480 Mbps.
