Benchmark pass suggests that the 64-bit, octa-core Snapdragon 810 has been put into testing

The 64-bit, octa-core Snapdragon 810 touts an Adreno 430 GPU, and two sets of four Cortex-A57 and Cortex-A53 cores, respectively. All said, this new combo is expected to provide some serious performance benefits over the Snapdragon 805 -- up to 50% more speed, while also drawing considerably less power.
In case you were wondering, the SD810 was powering what we guess is a prototype device with a 6.2-inch, 1600 x 2560 pixel resolution display and 4GB of RAM (that the SD810 can address in their full). The device in question was running Android 4.4.2 KitKat.

2015 can get here sooner -- that's all we're going to say.
