Qualcomm may have two more processors in the cards for May 9
Judging from previous leaks, the 630 and 635 will be similar in design, but bumped to 2.5GHz maximum speed and possibly made on a more modern fabrication process (think 10nm). This could potentially result in increased power efficiency. The chips are capped at LPDDR3 RAM, so they won't usher in an era of mid-range handsets with cutting-edge LPDDR4 RAM, but that's not much to fret over as DDR3 is still fast and efficient technology.
Overall, not much to write home about as far as these upgrades are considered. But it's good that Qualcomm is keeping its mid-range solutions up to date. This class of processors offers the potential for a very adequate user experience in terms of speed and battery life, as well as advantages of premium phones such as fast charging and 4K video capture/playback. The more the affordable handsets powered by these chips can offer users, the better!
However, Qualcomm's most relevant May 9 announcement is definitely going to be the Snapdragon 660 processor. You can read more about it here.
