The iPhone 7 version with Intel modem gets whacked by the Qualcomm model in weak signal areas
For now, however, Qualcomm still has the upper hand when it comes to cellular modem design, as it covers a wider range of LTE bands, and more wireless connectivity standards in a single chip, taking better advantage of carrier aggregation. This has recently been empirically proven with elaborate LTE connection testing equipment.
It turns out that in ideal conditions, both modems perform admirably, maintaining strong signal, and able to take advantage of similar maximum download speeds. When coverage gets weak or spotty, however, Qualcomm managed to pull ahead with about a 30% better performance on average, compared to the Intel version of the iPhone 7 Plus. Oh well, that's not going to affect your real world usage too much, but it shows that Intel still has some catching up to do with Qualcomm's cellular modem designs. Another interesting fact is that it was actually the Galaxy S7 edge, of all the phones tested, that pulled way ahead of all designs, and this one has Samsung's in-house Shannon LTE modem chip.
