Something tells me that unless Intel can get their sh** together, the next iPhone will have Qualcomm modems across the board.
With the iPhone 7 and the iPhone 7 Plus, Apple elected to use LTE modems from two different sources, Qualcomm and Intel. The A1778 and A1784 iPhone models use a GSM-only Intel XMM7360 modem while the A1660 and 1661 iPhone models use a GSM/CDMA-compatible Qualcomm MDM9645M modem.
Apple's decision has already caused some disappointment among customers because the GSM-only Intel modem is not compatible with as many carrier networks as the GSM/CDMA Qualcomm modem, and now independent testing conducted by Cellular Insights suggests there are some significant performance differences between the two modems, with the Qualcomm modem outperforming the Intel modem.
Using an R&S TS7124 RF Shielded Box, two R&S CMW500, one R&S CMWC controller, and four Vivaldi antennas, Cellular Insights created a setup to simulate LTE performance at different distances from a cellular tower using two iPhone 7 Plus devices, one with an Intel modem and one with a Qualcomm modem.
The goal of the test was to measure the highest achievable LTE throughput starting at a Reference Signal Received Quality of -85dBm (a strong signal) and gradually reducing the power level to simulate moving away from a cellular tower where signal is weaker. Three LTE bands were tested: Band 12, Band 4 (the most common band in North America), and Band 7.

In all three tests, both the iPhone 7 Plus models offered similar performance in ideal conditions, but as power levels decreased, Cellular Insights saw "unexplainable sharp dips in performance" in the Intel modem, finding a gap "north of 30%" in favor of the Qualcomm iPhone 7 Plus. In the charts, the Qualcomm modem maintains noticeably higher throughput speeds than the Intel modem as signal strength decreases.

In real world conditions, this would suggest the Qualcomm modem does better in areas where the cellular connection is weak, with faster throughput speeds. Cellular Insights describes the Band 12 test below:Cellular Insights also created a chart that compares the edge of cell performance of several different smartphones. The increasing numbers on the X-axis below represent increasingly poor signal strength, while on the Y-axis, a higher throughput number indicates better performance. The iPhone 7 Plus with an Intel modem demonstrates the poorest performance of all phones tested.

According to Cellular Insights, in every single test, the iPhone 7 Plus with a Qualcomm modem "had a significant performance edge" over the iPhone 7 Plus with an Intel modem.

I rare experience. Having an iPhone on Verizon has an LTE benefit. Haha.
In order to save a few $ by pitting suppliers against each other, Apple shortchanged their customers. I have the Intel version, and I'm very upset with this. First, it is severely constrained when traveling abroad. And now, even when at home, it is inferior to the same price Qualcomm version. Shame on you Apple. Give a partial refund to customers with an Intel modem. You sell two products at the same price, one is clearly inferior to the other, but you don't tell customers. You should charge less for the Intel version.
I have the slow HDD and an Intel modem. This is the fastest, most reliable iPhone I've ever had and I've had an iPhone since the 3G. I get signal on a woodsy road where my 6S did not. No complaints.
I love my 7+.

Why are you just pulling random numbers from thin air?There's no significant difference between the two. In their "lab", the throughput difference was 20%. In the real world, it's probably closer to 5%.

This is a total non-story. Any significant drop off on these charts starts at -105dB.
That's BARELY two bars (1 bar is -107 and lower). Plus their controlled test doesn't take into account any attenuation due to atmospheric conditions.
NON-STORY.
Why oh why doesn't Apple single source these key components,
Nothing ticks off a customer more than the feeling that their phone is performance-disadvantaged to other same model iPhones due to chance.
