Selling in Russia, the model of the iPhone 7 with the Intel modem has shown itself worse in tests of the speed of the Internet than the devices with the module Qualcomm, intended for the US, China and Japan.
Previously, Apple used only Qualcomm modems in its smartphones, but in 2016 it began installing Intel modules in devices designed for some countries and operators.
As demonstrated by the check of the New York-based analytical company Cellular Insights, Intel chips do not always show themselves in the best way. In ideal conditions, they and Qualcomm modules produce the same speed, but the worse reception, the worse the performance of Intel. The average gap is about 30%.
As the “Vedomosti” note, the owners of the iPhone 7 with the Intel chip can notice the difference in speed if they move away from the window deep into the premises. In the open air it will not be so significant. However, the contrast between the two types of devices for most users will reduce the regular use of Wi-Fi.
Apple sells the iPhone 7 with the Intel modem and in the US, but only operators of AT & T and T-Mobile networks, while Verizon and Sprint got faster devices. Cellular Insights suggests that the manufacturer can reduce the gap in the quality of the connection between the chips programmatically, because the Intel module simply begins to reduce the size of the useful block of transmitted data with a loss of signal, rather than the module Qualcomm.
Recently, this is the second time that Apple is accused of concealing from buyers the use of components of different quality in different models of the iPhone 7. For example, the memory module in the iPhone 7 at 32 GB was several times slower than that in the iPhone 7 at 128 and 256 GB. However, we are talking only about the write speed, when you load and open applications, the devices behave almost identically. The biggest gap can be seen by copying on iPhone 7 movies or other large files via cable.
In iPhone 6s, the same situation applies to processors. Some of them were manufactured by Samsung, and some by TSMC, and devices with Korean company chips under heavy loads worked almost two hours less. However, Apple then said that in daily use, the difference between the two devices will be virtually invisible.
Analysts associate such solutions with the inability of one vendor to cope with the huge demand for the iPhone, so Apple has to order some components from different partners, because of what they can differ in quality. Android manufacturers also often resort to this tactic: in particular, Samsung sold flagships with processors that differed not only in performance, but in architecture in general.
