Details about the unreleased Qualcomm Snapdragon 815 have been leaked by a source and published in a new report on Sunday. According to this tipster, the Snapdragon 815 will feature four Cortex A72 cores and four Cortex A53 cores. That means that the chip will use the big.LITTLE architecture with one set of four cores in use at one time. The Cortex A72 cores will handle the heavy lifting while the Cortex A53 cores will take care of the light housekeeping. According to the source, Qualcomm might "tweak" the cores.
The chipset will employ the next-gen Adreno GPU which is expected to be the Adreno 450, and will be built using the FinFet process. Earlier this year, an alleged Qualcomm roadmap revealed that the Snapdragon 815 SoC would include LDDR4 RAM and use the MDM9X55 LTE-A Cat.10 modem.
If you're worried about the Snapdragon 815 overheating like the Snapdragon 810 originally did, it looks like Qualcomm has solved this issue. A recent test conducted internally by Qualcomm shows that the Snapdragon 815 runs cooler than both the Qualcomm 810 and Qualcomm 801 chipsets. By the way, if you're wondering why the Snapdragon 815 has yet to be released by Qualcomm, it's because the latter wants to ring up as many sales of the Snapdragon 810 as it can before demand wanes for that SoC. The Snapdragon 810 is currently found on such recent phones as the LG G Flex 2 and the HTC One M9. You will also find the Snapdragon 810 SoC inside the LG G4, Sony Xperia Z4 and the Xiaomi Mi Note Pro once those models are released later this year.
