The 2021 iPhones will use Qualcomm's Snapdragon X60, which can aggregate 5G data more efficiently for better speeds and coverage. This is likely where a lot of the production cost will go, which is why Apple will continue to cut iPhone costs in other areas to better accommodate 5G chip technology. Barclays seem to think iPhone 13 models will support Wi-Fi 6E, which offers the same features as Wi-Fi 6, just extended into the 6GHz band. This means higher performance, lower latency, and faster data rates, as well as increased bandwidth across existing 2.4 and 5GHz Wi-Fi bands, leading to more consistency in performance in denser environments. Gamers should also froth on the lower latency, meaning their inputs will be faster and more responsive.
