He iPhone 7 has come to Manzana in this generation in two variants. The first is the GSM/WCDMA/LTE with modem Intel; and the version GSM/CDMA/WCDMA/TD-SCDMA/LTE of Qualcomm. The first signs of a difference in performance between the two models already seem to have appeared.
According to the results of the reports, it turns out that the iPhone 7 that is equipped with the Qualcomm MDM9645M modem of the A1660 and A1661 for Verizon, Sprint and models without a SIM card; It maintains better performance than the A1778 and A1784 versions, which have the Intel modem inside. Also, not only this, but it seems that the function that allowed to take advantage of the Ultra HD Voice has been disabled from Qualcomm models.
Regarding this fact, it turns out that Apple might have decided to disable the Ultra HD Voice feature. This function allows a Significant improvement in audio quality over cellular connections. The decision could be due to an attempt to level the playing field with that which is present in the Intel versions of the iPhone 7.
For now, the EVS It has only been installed on the network of T Mobile; so coverage would be somewhat limited in the US. The phone company claims that EVS offers many notable benefits to its customers. Benefits include improved call consistency in weak signal areas; and, apparently, higher fidelity than HD Voice, as EVS provides a higher audio frequency range. The latter means that the audio of the voice can sound richer and more realistic.
iPhone 7 network performance with Qualcomm modem outperforms Intel
In terms of phone performance, the report begins comparing LTE flow measurement for both iPhone 7 Plus devices, both the one with Intel and Qualcomm. Some findings indicate that both versions are capable of maximizing the sustainable flow of information; but, when reducing the power levels to simulate a scenario of using edge technology, each mobile responded differently.
For example, in the graph above, you can see how band 12 (10 MHz) differs in performance between the two basebands during a controlled environment test. Notice how the performance of the XMM7360 (Intel) version drops drastically; while power levels are reduced.
Band 12, which is a low frequency band, can propagate further; and penetrate walls better than high frequency bands. In other words, it’s a frequently needed band. when using LTE inside buildings. Note the significant difference in performance of around -108 dBm.
In a nutshell, after these and various other tests, the iPhone 7 hardware powered by Qualcomm was found to perform better on Edge than the Intel variant; despite having been tests carried out in controlled environments.
