This brings us to the coming generation of 64-bit chips, and at the top of the heap is the Snapdragon 810. This is the chip that will power many of the top phones of 2015, but it's a significant departure for Qualcomm. Here's everything you need to know about the 810.
More CPUs, with less customization
Qualcomm rose to dominance on the strength of its custom ARM-compatible CPU cores. Just like Nvidia, Qualcomm purchased an instruction set license from ARM Holdings to design its own cores that are compatible with ARM software. The first generation of custom CPUs from Qualcomm were called Scorpion, which powered the original Snapdragon. After that we moved on to multiple CPUs in the Krait family. The Snapdragon 810 is different because it's not running a custom CPU designed by Qualcomm—the Snapdragon 810 is powered by eight ARM reference cores.
