Qualcomm unveils 2Gbps X24 modem, hinting at 7nm Snapdragon 855 for the Galaxy S10
The X24 gear can still be considered pre-5G, though, as phones with it would still need to have the 4G LTE modem part that can hit 2 Gbps, with an extra chippery on board that could use whatever early services the US carriers' 5G networks can offer. We aren't really talking only about speeds here, as to experience true 5G they'd need to use millimeter-wave networks that are only feasible to cover city centers with, and the 5G modem set for those is the X50, coming in 2019. The other aspects of a 5G network are no less important, though, such as extremely low latency, and the ability to hook up much more devices to a single tower.
We know what you are thinking - when can I get 5G on my phone, right? Well, as soon as next year, maybe with Snapdragon 855 on the Galaxy S10, or whatever Qualcomm and Samsung name those products, if the X24 there is packaged with a X50 "subsystem," as per Qualcomm's Sherif Hanna quote below. Oh, and if the first 7nm chipset announced is a cellular modem that is likely to go into Snapdragon 855, we can safely assume that the move to 7nm is happening for Galaxy S10, and should do wonders for its performance/battery life ratio.
The plan for smartphones is that you'll have an SOC with an integrated gigabit LTE modem, and the 5G subsystem which includes the 5G modem will exist alongside it on the board. I would say that's in a 5-inch or 5.5-inch class device. The footprint of the chips is pretty small.
