Request: Can someone who has AT&T or T-Mobile get both a Verizon and GSM-Only iPhone X to speedtest?

[Starfyre]

I have an ask for anyone who has access to both iPhone X. I want to know for the Verizon iPhone X, is the download and upload speed faster than T-Mobile or AT&T carrier specific iPhone X?

Please use Ookla’s Speedtest.net, make sure the server used is the same for both cases and share results please.

I want to know if results are consistent with other iPhones:

Tried this with my Qualcomm X and my wife’s Intel 8+. Although her signal strength was consistently 1 bar higher (e.g. I’d have 2 and she has 3), our upload and download speeds were both the same, and terrible. 30 down and 8 up maximums. AT&T coverage in our house for some reason is just no good. My Verizon 6s just pulled down 60 mbps and uploaded 12. I might try to swap my Verizon sim into my X just to see what happens.

Thanks for reporting the result! Perhaps Apple has handicapped the Qualcomm chip to make it equivalent of not worse? If that is the case I would not mind just keeping the carrier specific model. Let us know what you find.

If others can also do this test, that would be amazing!

I waited at the store yesterday to get the Qualcomm version and I see no difference between it and the intel modem in my 7. The Speedtest I’ve done have all been between 1-3 mbps of each other. At home I have 3 bars on each and download was 24 on intel, 23 on Qualcomm. Upload was 9 on intel and 12 on Qualcomm. I’m a little mad that I played into the Qualcomm hype and waisted time lining up yesterday. My AT&T X came in yesterday so there was no point

The places the Qualcomm chips shine are in low signal areas.

Wait, can you open up your AT&T X and do the same testing on that one to compare your AT&T (Intel X) with the Verizon (Qualcomm) X?

I would love to see an actual test of this at this point.

I just read some of MacRumor's older frontpage posts like this:
https://www.macrumors.com/2017/09/26/iphone-8-teardowns-modems/

Intel, on the other hand, claims up to 15 percent lower power usage compared to its previous-generation modem, which could be thanks in part to the newly included envelope tracker for voltage control, which reduces power usage and heat. While it is not clear which process Intel's modem is built on, it seems likely it is still a 28nm process from TSMC, as Intel still works on the technology lineage from its Infineon acquisition. Nevertheless, future iPhones will be well-positioned to include higher bandwidth and more diverse network capabilities in the future, even if the modems they use stay the same.

The above is referencing the iPhone 8. This might negate the 'battery life' advantage on the Qualcomm.

It is if it is real, like these tests are to be believed. Look how much higher the performance is on the Qualcomm versions (unless this is a sham):
https://www.macrumors.com/2017/09/28/iphone-8-cellular-bandwidth-tests/

Rate limiting should have occured on the older phones already back in November 2016: http://appleinsider.com/articles/16...em-to-keep-performance-on-par-with-intel-chip

What this shows is that even after Apple artificial rate limiting, the Verizon still performs better than the GSM-only Intel model.

I thank 2 people who have tested this live and experienced results that really didn't make much of a difference (with the exception of 1 bar higher on the Intel contrary to opinions that Qualcomm has should have better signal).

Is that AT&T on both though? I was going to suggest using Field Test mode to get the actual signal strength in dB, but apparently that display has been removed from field test mode in iOS 11. :-(

Personally, I don't care about a minor download speed difference and specifically didn't pre-order an X because I was waiting for the SIM-free model due to better handling on weak signals on the Qualcomm modem. I'm on an AT&T iPhone 7 right now and over 25% of my battery loss according to the battery thing is due to "No Cell Coverage". I do have terrible service at work, but the iPhone 6 that my 7 replaced had better service in that area consistently. I'll get no service at all some of the time, whereas the 6 could recover quickly if I was trying to use it.

There were reports of the opposite behavior here shortly after the iPhone 8 came out, where someone mentioned having both iPhone 8 models and the Qualcomm one consistently had better service. That's what I was basing my decision on, since I wanted the phone that will behave better when it has a weak signal. (There were also speed test comparisons of the 8 that consistently worked in favor of the Qualcomm model)

I really hope the opposite doesn't end up being true, just because it means I waited for nothing and could've had a phone yesterday.

Much higher speeds and better signal on the iPhone X using the Verizon version on AT&T/TMO. But you already knew that, that's why you created this thread, to see if the phone you have been obsessing over needs to be returned. It does. It kills you that you have the inferior version. Just do yourself a return it now.

 

[lordhamster]

I’ve got a Verizon version (with T-Mo Sim installed) and my wife has a T-Mo version which she hasn’t opened yet. I’m on a plane right now and won’t be back for 2 weeks.... but if nobody has done the test by then, I can do a control test for you with the same provider in the exact same area.

More tests in my Qualcomm X and Intel 8+ are nearly identical in terms of signal and network speeds on AT&T and since AT&T for some reason is garbage in and around NYC, speeds are low. Switched in a Verizon sim from my work phone and the speeds jumped 5 fold. So, on AT&T in NYC Qualcomm and Intel modems appear indiscernible from my n=1 study.

 

[Ron21]

I can only compare the GSM X or my Qualcomm chip 7 Plus, the GSM Intel X is consistently 1 bar higher in the exact same location. This is using T-Mobile.

Regarding speed, it's about the same for the most part.

In some tests, the Intel iPhone X a tad faster by ~10% but other runs, it's very close to the same result. So I think it's just the network and not any difference the chips.

 

[tivoboy]

people doing the same test, in different areas with different sims is going to give you nearly MEANINGLESS data. If you really want to compare you've got to get both phones connecting in similar areas with the same SIM and run the test.

You seem like one of those people looking for a story that isn’t there. Do you really have nothing better todo? Maybe go post some more to your insta story.

I totally agree! AT&T service is just brutal in and around New York City.... makes zero sense!!

Here you go! 11 Rounds, each with 3-6 trials averaged together. All using same sim (swapped between phones each round for data collection), and with phone placed in exact same location, testing connections to 3 different servers.

Yup, Q modems are throttled.
