Even before the Snapdragon 810 actually made it into real life smartphones, we’ve been hearing the platform was plagued by pesky overheating issues.
Qualcomm has been avidly refuting this information, but the thing is, whispers related to the matter just didn’t seem to make themselves scarce.
Things escalated to a point where Japanese carrier NTT DoCoMo decided to put up a warning poster for several smartphones that were all powered by the Snapdragon 810, urging users of these models to take into consideration the chip’s overheating issues and follow a set of instructions in order to be on the safe side of things.
So while the Snapdragon 810’s reputations seemed doomed from the get-go, a lot of people were hopeful the next-gen Snapdragon 820 will come to fix things.
Will the Snapdragon 820 have similar problems?
Well, this weekend, a Tweet from self-proclaimed “tech secret agent” Ricciolo raises doubt that the Snapdragon 820 might be able to resolve the problems its predecessor had.
Ricciolo states that the Snapdragon 810 and Snapdragon 820 won’t be so different in terms of heat issues. He also advises mobile phone enthusiasts to wait for the Snapdragon 830 with the mention that the latter won’t become available until the third quarter of 2016.
The tipster hasn’t posted any relevant information that backs up his claims, so for the time being you better take this piece of information with a grain of salt, as we won’t really know for sure until the first phone running the platform goes official.
But Ricciolo’s statement does seem a bit far-fetched if we're to take into consideration the fact that the Snapdragon 810 uses stock ARM cores, while the Snapdragon 820 has Qualcomm’s own custom cores inside it. Basically, they are two totally different affairs.
Anyhow, according to well-known Chinese analyst Pan Jiutang, this will be the Xiaomi Mi5 Plus. He also claims that Qualcomm will begin shipping out the Snapdragon 820 in December of 2015.
Things we know about the Snapdragon 820
Qualcomm’s next-generation premium tier system on a chip platform will be designed on a current FinFET process note and built upon a custom 64-bit CPU architecture called Kyro.
Because it utilizes 14nm FinFET fabrication technology by Samsung and GlobalFoundaries, it means the Snapdragon 820 will be built on the most efficient process that’s currently available commercially.
The Snapdragon 820 is expected to take advantage of a dual-cluster quad-core CPU with two cores operating at 1.7GHz plus two running at 2.2GHz. Kyro cores are said to be able to support the maximum frequency of 3GHz, but that doesn't mean Qualcomm will push limits on the CPU to that extent.
