Apple is throttling the Qualcomm modem in Verizon and Sprint iPhone 7 for parity with slower Intel modem model

Apple is throttling the Qualcomm modem in Verizon and Sprint iPhone 7 for parity with slower Intel modem model
One of the behind-the-scenes facts about the new iPhone 7 and 7 Plus is that units on different carriers have different integrated modems. Verizon and Sprint units use the Qualcomm X12 modem, while AT&T and T-Mobile use the Intel XMM 3360 modem. Does this matter? In practice, not really, but it is your right to know that the Qualcomm modem maxes out at speeds of up to 600 megabits per second, while the Intel modem's max speed is around 450 megabits per second. Thus, Apple has throttled down the faster Qualcomm modem in order to keep parity between different carrier models of the iPhone 7.

According to analyst Jan Dawson who's familiar with the matter, the decision has to do with Apple's supply chain more than anything. The company chose to use the two modems to differentiate its suppliers, which carriers had no real say in. Moreover, marketing the same phone as faster on Verizon or Sprint's network because of these matters would have been unfair to competing carriers and users themselves. But in testing, the Qualcomm modem model was found to be slightly faster than the Intel modem model, although not considerably so.

In addition, Apple might be considering the increased power consumption of the non-throttled Qualcomm modem in its decision.

What about the sim free one? Which one does it use?

Does it matter? Because they are the same speed thanks to throttling lol.

These model numbers are the ones with Intel A1778, A1784. If it isn't one of these then it has Qualcomm's modem

Correct me if I'm wrong, but I believe the Intel modem isn't CDMA-compatible. So it'd stand to reason that the SIM-free model would have the Qualcomm modem, just like the Verizon, Sprint, Chinese, Japanese and Best Buy variants.

Who is actually hitting these speeds...

Absolutely no one. There is no throttling because no carrier can currently push that bandwidth regardless of aggregation.

Doesn't matter about the max speed in this case but the real question is, is Apple doing this to older devices as well? The speed decreases and stutters and lags that older devices face after updates seem very artificial seeing as how nothing changes in terms of added features or complexity in art, but a device capable of full 3D games starts stuttering while rendering 2D frames. Not only that, but it also starts being sluggish while opening the same apps even ones not designed by Apple. If they can do this for streamlining the experience, then they can do it to worsen it too.

That is why people should invest in home internet/wifi. I'm not worried about the speeds while I'm out in public. I update on average about 20 apps a day. That would result in 1gb a day if I updated through LTE. Takes less than 3 mins on my Xfinity.

All in all considering monthly data allotments the fact that it's throttled is virtually irrelevant. However the Galaxy S7 has the same Qualcomm modem as the iPhone and it was tested to be ~up to 2x faster than the iPhone.

And the reason not all iPhones have qualcomm's modem which not only supports more bands than the intel ones but has faster speed is? GREED and blatant profit from Apple. They are not ever ever putting the best of tech that they can in the iPhones lately and its pissing me off. The S7 beats the s**t out of an iPhone in band support and 4G speeds.

Same on mine s7 edge Internet is slower than on mine vivo X5Pro..
