Under poor network conditions, the iPhone 7 Plus with Intel inside does not perform as well as the iPhone 7 Plus with Qualcomm inside. Apple sourced the iPhone 7 Plus modem from both Intel and Qualcomm. This represents a major change for the company, which has relied solely on Qualcomm modems for years. The Intel modem (XMM7360) is found in the AT&T and T-Mobile variants of the iPhone 7, while the Qualcomm modem (MDM9645M) is found in the Sprint, Verizon, and unlocked variants of the iPhone 7. Cellular Insights conducted extensive signal tests on the iPhone 7 Plus in LTE Bands 12, 7, and 4 to see if any performance differences exist between the two modems. Under optimal network conditions both the Intel- and Qualcomm-equipped iPhones demonstrated an equal level of performance in speed and maintaining a connection. Under weak network conditions, however, the Intel-equipped iPhone 7 Plus posted speeds that were on average 30% slower than those of the Qualcomm-equipped iPhone 7 Plus. The slower speeds at the cell edge mean the Intel-based iPhone 7 Plus may be more likely to experience dropped VoLTE calls and other, similar behaviors. "In all tests, the iPhone 7 Plus with the Qualcomm modem had a significant performance edge over the iPhone 7 Plus with the Intel modem," said Cellular Insights in its report. Apple has not said why it selected modems from two separate suppliers for the iPhone 7 Plus.

Apple should of stopped this

They should of never let these Intel units out until Intel resolved this issue. If they couldn't resolve, no deal. Network performance should be top priority for these manufactures on all fronts.
It was about the money, Id be willing to bet Intel wasn't charging as much as Qualcomm but their performance is always worse.
The same thing happens with Most intel products other than desktop/laptop CPUs.
Look at their GPUs or Android processors, m...
