Last week, the LeTV Le Max Pro became the first smartphone to be announced with the Snapdragon 820 SoC inside. That phone also carried revision 1 of the Snapdragon 820 SoC when it was benchmarked. The chip features a quad-core CPU that employs Qualcomm's own Kryo cores. Also included is the Adreno 530 GPU. There is some speculation that in the first half of 2016, Qualcomm will offer a version of the Snapdragon 820 with an octa-core CPU. The report, which we told you about last November, said that several phone manufacturers like Samsung, Huawei, ZTE, Sony and LG are committed to the use of octa-core CPUs.
At the moment, we have no idea what the revisions to the chipset entail. There has been some concern that the Snapdragon 820 SoC suffers from the same overheating issue that affects its predecessor. Perhaps some revisions were made related to that problem.
While the Rain Rain A3000 is unknown, we do know that it contains 4GB of RAM and is pre-installed with Android 6.0.1.
