Every iPhone X Is Not Created Equal (pcmag.com)
According to a PC Magazine report that uses data from Cellular Insights, the Qualcomm-powered iPhone X has better LTE performance than the Intel-powered model. From the report: There are three iPhone X models sold globally. Using lab equipment, Cellular Insights tested two of them: the Qualcomm-powered A1865, sold by Sprint, Verizon, and U.S. Cellular and in Australia, China, and India; and the Intel-powered A1901, sold by most other global carriers including AT&T and T-Mobile. (The third model, A1902, is only sold in Japan.) Here in the U.S., we anticipate that the SIM-free model sold directly by Apple will be the A1865, as that's the model that supports all four U.S. carriers. For this test, Cellular Insights looked at performance on LTE Band 4, which is used by every major U.S. carrier except Sprint, as well as in Canada and parts of Latin America. Cellular Insights attenuated an LTE signal from a strong -85dBm until the modems showed no performance. While 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. Most consumers will feel the difference in very weak signal conditions, where every dBm of signal matters, so we zoomed in on that in the chart below. At very weak signal strength, below -120dBm, the Qualcomm modem got speeds on average 67 percent faster than the Intel modem. The Intel modem finally died at -129dBm and the Qualcomm modem died at -130dBm, so we didn't find a lot of difference in when the modems finally gave out.
Was staying out in the bush this week, both of my companions had service on their cheapo Android phone, my iphone did not, very poor reception at fringes indeed.
Not too surprising, or not surprising at all, since Apple multi-sources components and they're not exactly the same. *shrug*
dBm of attenuation. Someone flunked Microwaves101.
Or do you mean "Not Every iPhone X Is Created Equal"?
That's interesting. Get them out in the field. Sensitivity is not the only measurement that matters. In some cases, it's the least important measurement. Noise rejection and selectivity are usually more important in urban environments when you get crazy ghosting from signals bouncing off of buildings. Unless you have an insanely expensive RF capture and playback setup, you aren't replicating that in the lab.

when you say "only 6db", you can also say it as "only about a 50% stronger signal"
Intel is a stupid company. It's the truth. People are just too polite to verbalize it. Until now. I hope they close shop soon enough. It's a reaccionary company, unfit for progress.
The correct phrase is "not every iPhone X is created equal." That means some are equal, but not all.
TFH says "every iPhone X is not created equal." That means each and every one is different for all the others. That is incorrect.
Sorry for ranting, but every time I see this mistake, I die a little.
If it weren't for deadlines, nothing would be late.
Not every iPhone X is created equal.
I bet your fun at partys.
oh my god a negligible performance difference release the hounds
I seem to recall this dual sourcing of chips causing a significant difference in battery life in previous iPhone versions. Did anyone test if the batteries last as long on both variants?
I don't care much of the data rates on the phone's modem. WiFi is easy enough to find for when I want to avoid data charges and need speed. All I need the modem for is maps, e-mail, and some web browsing so I'm not concerned if the data is 50Mbit or 150Mbit. What does concern me is if the phone eats up its charge.
This speed testing is still interesting, but not what concerns me much. I'd just think that if they went through this effort of testing that the battery life testing would not have added much to their efforts. Given battery problems in the past I'd think that would be something many others would be curious about as well.
I am armed because I am free. I am free because I am armed.
about just about every model? Apple doesn't single-source-source modem chips; as a result, they get minor but measurable differences in performance between manufacturers. Shocking, really.
At $1100, I just don't care. Its about $500 more than I've ever paid for any phone that I've ever owned, including my Galaxy S8, and as far as I can tell, it doesn't do anything more or better. Actually if anything it seems worse in several areas. https://www.wired.com/story/ha...

Apple has issued a statement saying that Cellular Insights was testing it wrong. All iPhones are fantastic.
This is one of many reasons why I refuse to buy Apple products anymore.
They are charging an absurd premium for this equipment, and I can't even get a guarantee that the parts in it will be "good". Their computers are no better, a lot of their laptops have tinting or ghosting issues dependent on the manufacture of the LCD display- and much like the iPhone X, there's no guarantee you'll get a computer with a proper screen.
This sort of behavior is a fucking insult to their customers. They do it because it's good for business- they don't want parts stockpiled sitting around, so they just source from whatever manufacture they can, leading to a situation where one machine P/N has a ton of different parts and at least 2/3rds of them are not ideal.
I wouldn't care as much if they were charging reasonable prices for their equipment, but they're not. They are literally saying "haha you're stupid to pay this much for a shit device" and letting you play parts lottery with the internals. It's just a shame their customers seem unwilling or unable to realize what sort of games Apple is playing and respond accordingly, since it seems like the only thing everyone cares about these days is the Apple logo on the back.
It's a fucking tank on steroids. It may not be as FAST as the latest iPhone (it's a 2016 phone) but it gets signal where the iPhone will not (and on the same carrier - Verizon, out in the Hauser Geode Beds in middle-of-nowhere Imperial County. Closest facility? A state prison almost 20 miles away.) Hell, this phone is designed to withstand solar radiation, which means this thing should fucking work in orbit, and probably even on the moon. Oh, and it works through gloves up to 3mm thick.
Enjoy your shit new hardware that can't even hold a candle to the usability of older hardware.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
I'll never buy an iPhone.
