Qualcomm's iPhone X Still Outpaces Intel's

Qualcomm’s Modem beats Intel’s Modem in IPhone X

Cellular Insights recently tested modem strengths in both modems, that is of Intel and Qualcomm in the IPhone X models. The tests proved that Qualcomm was able to give consistently higher speeds that Intel’s modem in the IPhone X.

Since IPhone’s 4s to 6s, Apple has always made use of Qualcomm’s models. But as of the IPhone 7, Apple has begun to split its modems between Intel and Qualcomm. This has resulted in IPhone 7 models with very different signal speeds.
 

Two models of IPhone X tested:

 

Cellular Insights used two IPhone X’s two test LTE signal speeds. The A1865 model, which is a Qualcomm modem phone and the A1901 which is an Intel powered modem phone was picked for testing. The A1865 model is sold by Sprint, Verizon in the U.S. and it is also sold in India, China and Australia. The A1901 Intel modem Phone is sold by U.S. carriers AT&T and T-Mobile.

There is a third model of IPhone X too, but it is only sold in Japan and was not a subject of this testing.

The testing was conducted on a common band which is used by all major carriers in the US.
 

How was the testing between Qualcomm and Intel modems tested?

 
Cellular Insights tested signal strengths and the speed of downloads, in a range of- very good signal strength to very bad signal strength. That is from -85dBm to whenever the IPhones would quit getting a signal.

On a 20MHz band, both IPhone models started out with a speed of 195Mbs but after that the difference became more apparent. The Intel modem download speeds dropped to 169Mbs at a signal strength of -87dbm while its competitor took another fall of -6dBm in signal strength to reach download speeds of 169 Mbs.

Where every drop in signal strength can be felt by customers, Cellular insights took to testing the Intel and Qualcomm modems to the last when both phones got no signal. At signal strengths of -120dBm which is a very poor signal strength, the Qualcomm modem still outperformed the Intel modem by a whopping 67%.

The point when both modems finally lost signal was -129dBm for the Intel modem and -130dBm for the Qualcomm model, which is not a whole lot of difference.

Cellular Insights used the very best in testing both modems including CMWFlexx solutions and they also used the same technique as they had previously used for testing signal strengths in phones.

Since the last testing, Cellular Insights has found out that Qualcomm has always outperformed Intel modems but today the difference between both modems is becoming narrower. This maybe a deliberate action rather than a drop in performance by Qualcomm modems.
 

Is it the end of the road for Qualcomm?

 
Apple and Qualcomm have found themselves in a web of lawsuits that has mostly to do with Apple refusing to pay Qualcomm license fees. So the IPhone X may be Qualcomm’s last stint at Apple.

Apple has previously stuck to Qualcomm modems because of its good performance and also because only the Qualcomm modems could run on Verizon and Sprint CDMA networks. Now Intel is going to change all that with its XMM7560 modem which will hit markets next year.
