Based on our benchmark showdown, the A11 Bionic chip in the iPhone X outmuscles the Snapdragon 845 processor in the Galaxy S9 when it comes to sheer horsepower, but there’s a speed test that’s arguably the most important where Samsung’s flagship is way ahead of Apple’s.

Galaxy S9 vs iPhone X: 4G LTE Performance Compared
|Galaxy S9+ (T-Mobile)||iPhone X (T-Mobile)|
|Average Download Speed||71.6 Mbps||48.8 Mbps|
|Average Upload Speed||10.1 Mbps||7.7 Mbps|
|Video Download Time||18.8 seconds||35.9 seconds|
|Photo Upload Time||20.7 seconds||44.4 seconds|
The Galaxy S9 is equipped with a Qualcomm X20 Category 18 downlink LTE modem that supports peak download speeds of up to 1.2 Gbps. The iPhone X we tested, which has a Qualcomm X16 modem, is a Category 16 downlink modem that supports up to 1 Gbps speeds.
For our testing, we used a T-Mobile SIM card and tested in the same location in New Jersey. We used the Speedtest.net app to gauge throughput, which measures both download and upload rates.
The Galaxy S9+ averaged a very impressive 71.6 megabits per second over 5 runs, compared to 48.8 Mbps for the iPhone X. That’s a difference of 46 percent.
The upload speed delta between the two phones was not as dramatic. The Galaxy S9+ averaged 10.1 Mbps, versus 7.7 Mbps for the iPhone X.
For a real-world test, I downloaded the same The Hobbit: An Unexpected Journey movie trailer from Google Drive on both phone. The Galaxy S9+ took 18.8 seconds and the iPhone X 35.9 seconds.
Lastly, I uploaded three photos totaling 8.1 MB to Dropbox from both the Samsung and Apple phones. The Galaxy S9+ took 20.7 seconds, while the iPhone X took twice as long at 44.4 seconds.
Overall, the Galaxy S9+ is a 4G speed demon, so be sure to keep its faster LTE in mind before you decide between it and the iPhone X.
