We have already seen a few images of the Sony Xperia Z3 surface, including some that contrast it with a Samsung Galaxy Note, but details about the hardware have been scant. Tipster @evleaks has supposedly unearthed some details about the hardware. According to a new post, the Xperia Z3 will feature a Snapdragon 801 running at 2.4GHz and mated with an Adreno 330 GPU. This is not a major step up from the Xperia Z2 and if accurate would be a disappointment for those who were hoping to see the Snapdragon 805 used. Other specs are more in line with what has been suspected for the device, including 3GB of RAM, a 20.7MP camera, and a 5.15-inch screen running at a full 1080p. The Xperia Z3 appears to be slated to come with Android 4.4.4 preloaded.
