“Always Connected” Windows PCs won’t just use ARM chips as Intel, AMD join the fray
Central to the promise of a new generation of Windows 10 on ARM PCs (the first two of which were announced yesterday) is the idea of being "Always Connected:" that your mobile PC, like your smartphone, is almost always online, using Wi-Fi where it's available or LTE where it isn't.
Qualcomm's Snapdragon 835 ARM processors are a good match for this because they integrate Qualcomm's X16 LTE modem. Paired with the right mobile network and antenna hardware, the modem is capable of downloading at gigabit speeds. But Intel and AMD have both been keen to highlight that you don't need an ARM processor for this kind of connectivity—and you might not need one for the other claimed ARM advantages either.
AMD announced a collaboration with Qualcomm to produce machines using its new Ryzen Mobile processors along with Qualcomm LTE modems, offering the same LTE performance as you'd get with a Qualcomm Snapdragon processor.
