Last week we commented on the processor performance of the new iPhones (A12 Bionic) and the higher speed achieved by the new devices on both Wi-Fi and mobile (compared to iPhone X) thanks to the modem. XMM 7560 from Intel, which supports MIMO 4 × 4 networks.
This technology is largely responsible for the LTE performance of the XS and XS Max iPhones over X, but not the only one. To analyze the performance jump of this modem, the PCMag released the results of its speed tests, comparing the new flagships from Ma with iPhone X, Samsung's Galaxy Note9 and Google's Pixel 2.
Remember that the iPhone X, as well as the iPhones 7/7 Plus and 8/8 Plus, was in the midst of the transition from Qualcomm modems to Intel. Therefore, as they were equipped with components from different manufacturers, they may present conflicting results.

Already in the first test, it is possible to verify the effect of the new MIMO 4 × 4 antennas. Under good signal conditions, the download speed on XS Max is double that of iPhone X and even under not so positive conditions it can maintain the highest performance. Compared to Note9 and Pixel 2, iPhone XS Max is a bit slower, but the difference gets smaller and smaller as the signal strength decreases.

Analyzing the signal at very low levels (below -120dBm), iPhone XS Max competes even more with Android devices, which use Qualcomm's X20 modem. Still, the Intel chip showed that it can't handle the jolt when it has to deal with the terrible reception and zeroed the download speed unlike Note9 and Pixel 2.

In the comparison between the two new flagships from Apple, they got pretty much the same result. THE PCMag just noted that the iPhone XS Max performs better at some specific signal levels; In practice, this is not enough to indicate a large difference between this device and the XS.
As we said, the modem is not solely responsible for the download speed of the new iPhones. Software is also a fundamental part of overall device performance and this may be why some users have complained about signal strength on new iPhones.
It is likely that the first versions of iPhones XS and XS Max firmware may in some places be causing problems with signal reception. Therefore, as no hardware problems were found, this issue can be resolved with a future software update specific to these devices.
In this sense, the PCMag It also proved a noticeable drop in performance from iOS 11 to iOS 12 on the iPhone X with Intel modem. With the new operating system, the device reset the download speed before others gadgets running iOS 11.
