Qualcomm Modem iPhone X Models  Have 67% Faster LTE Speeds Than Those With Intel Modems.

According to wireless signal testing firm Cellular Insights, Intel’s claim of faster LTE speeds than Qualcomm modem has been experimentally proved wrong.

Cellular Insights used professional measurement equipment equipped with four Vivaldi antennas to simulate LTE performance at different distances from a cellular tower with the Qualcomm and Intel models.

Cellular Insights started with a LTE signal from a strong -85dBm, and gradually reduced the power level to simulate moving away from a cellular tower where signal is weaker, until the modems lost their cellular connectivity.

The testing was based on performance on LTE Band 4 used by every major carrier in the United States except Sprint, as well as in Canada and parts of Latin America.

The verdict is that with only limited attenuation, or signal reduction in simple terms, the iPhone X with an Intel modem started to experience lower LTE download speeds than the iPhone X with a Qualcomm modem.with only limited attenuation, or signal reduction in simple terms, the iPhone X with an Intel modem started to experience lower LTE download speeds than the iPhone X with a Qualcomm modem.

Both modems started out with 195Mbps of download throughput on a 20MHz carrier, the Qualcomm difference appeared quickly, as the Intel modem dropped to 169Mbps at -87dBm. The Qualcomm modem took an additional -6dBm of attenuation to get to that speed.

According to Cellular Insights, the difference is most noticeable in very weak signal conditions, in which the iPhone X with a Qualcomm modem experienced 67 percent faster LTE download speeds on average compared to the Intel model.

PC Magazine speculated that Apple could be artificially crippling the Qualcomm modem to have similar performance as the Intel modem, given the controversy that arose with the iPhone 7 and iPhone 7 Plus last year.

So theoretically, the iPhone X with both Intel and Qualcomm modems have a peak download speed of 600 Mbps in most countries despite the Qualcomm modem being a Gigabyte class modem.

If you want the best possible LTE performance, purchasing the A1865 model is the best option. For now, this requires ordering the Verizon model if you want an unlocked device in the United States. In many other countries, and in the U.S. soon enough, Apple sells an unlocked SIM-free A1865 model.
