Qualcomm is introducing three new processors designed for phones and tablets: the Snapdragon 429, 439, and 632. Though these are the latest in Qualcomm’s 400 and 600 series processor lines, none of these processors reflect the best of what those lines have to offer — instead, they’re midtier options within each series, offering better performance than some of the entry-level options currently being used.

The Snapdragon 429 and 439 are supposed to be up to 25 percent faster and more battery efficient than the earlier 425 and 430 chips. The 429 supports either a single 16-megapixel camera or dual 8-megapixel cameras and a screen resolution of around 720p; the 439 supports a resolution of around 1080p and can go up to a 21-megapixel camera, or the same 8-megapixel dual camera alternative.
