Apple has been trying to divorce itself from chipmaker Qualcomm in bits and pieces, which you may already know about from the headlines about the ongoing legal spat. You may not know, though, that one of the consequences of this staggered departure is that some iPhone X units carry Qualcomm Snapdragon X16 modem chips while others have XMM7480 chips made by Intel.

According to a new study from Cellular Insights, which specializes in wireless download reports, you're getting better speeds if you happen to use an iPhone X with one of the Qualcomm chips than one of the iPhone X units with Intel modems. Naturally, this means that Apple's split with Qualcomm may not be as ideal as it would prefer.

According to the full study as reported in PC Magazine, the Qualcomm chips consistently did better, and the difference was especially noticeable in areas with weak signals. At an especially weak signal strength of -120dBm, for instance, the Qualcomm modem was still downloading at around 67% faster than its Intel counterpart.
