Even before most phone makers have launched their first 5G handsets, Qualcomm, the company behind the chips powering many of these smartphones, is already thinking about the second generation. Today, Qualcomm has announced the Snapdragon X55 5G modem, its follow-up to its first 5G modem, the X50. The chip-maker will make the new modem available to its partners in the coming months, and the first devices equipped with it should be out before the end of the year.

The headline feature of the Snapdragon X55 is its maximum download speed of 7 gigabits per second, compared to 5 gigabits for the X50. That’s technically a 40 percent improvement — even if a combination of geography, radio interference, and spectrum availability means you’re unlikely to see anything close to these theoretical limits in real world usage.
