There have been rumours floating around about a supposed Snapdragon 815 chipset coming from Qualcomm that was supposed to be carrying ARM’s bit.LITTLE architecture but the rumour has been quashed by Qualcomm stating that no such chip exists.
The Snapdragon 815 apparently was to have an octa-core CPU, Adreo 450 GPU, LPDDR4 memory support as well as a MDM9x55 modem built in with Cat.10 LTE; manufactured using a 20nm process.
Qualcomm on the other hand says that no such chip is going to be made, with the next top of the line chip to actually be the Snapdragon 820 which will succeed the Snapdragon 810. The new chip is expected around the latter part of this year with devices running on it to be out at either the tail end of 2015 or early 2016 assuming there are no delays.
The Snapdragon 820 will be the first 64-bit SoC to have a Qualcomm custom core, named Kyro, based on ARMv8 but designed by Qualcomm themselves.
