Octa-core Snapdragon 620 chipset leaks flaunting the new Cortex-A72 architecture
Two upcoming Qualcomm Snapdragon chipset specs have been leaked online, and they clearly employ ARM's just-announced Cortex-A72 architecture, codenamed "Maia". Dubbed MSM8976 and MSM8956, the chipsets will likely end up being in the midrange 600 family of Qualcomm, probably a Snapdragon 618 and 620, given that we already have a 64-bit Snapdragon 615 that powers handsets like the Galaxy A7. If you are wondering why not the top-shelf 800 family, bear in mind that Cortex-A72 will actually be an upper midrange CPU architecture, aimed at a good performance/power consumption ratio, while 

As you can see in the leaked spec sheet, MSM8956 will utilize two Cortex-A72 cores clocked up to 1.8 GHz, and four low-power Cortex-A53 cores, running at 1.2 GHz. The MSM8976, likely Snapdragon 620, will be an octa-core configuration, with four Cortex-A72 units taking the 1.8 GHz lead. Judging from the maximum clock frequency, these SoCs are likely aimed at the upper midrange echelon, rather than unleashing the full A72 power which will probably happen with a Snapdragon 8xx packaging of ARM's new architecture.

The rest of the specs show an Adreno 510 graphics processor that supports up to Quad HD displays at 60fps refresh rate, up to 21 MP camera sensor support, and 1080p video encoding at 60fps. Not too shabby, but, given that they are listed as 28nm, these are unlikely to demonstrate the up to 70% power savings promised by ARM upon the Cortex-A72 unveiling yesterday, as the new cores are made specifically with the 16nm process in mind. By the time these hit phones next year, though, Qualcomm might have moved to the 16nm conveyor belts, too.

This sound far better than the older leak

I hope the 820 is a Octa core with 4 A72s and 4 A53s
Having 8 of the same core leads to too low single core performance, i.e. MediaTeks

This is false. 600 series never uses powerful high end cores. This chip should be spiritual successor of the 808 and hence should be named 818 or something. Hence this leak is false.

Also even ARM said you'll see these a72 chips in 2016.

+1

also 28nm in late 2015/2016 ??????????????

it has to be 20nm atleast

This is missunderstood information.
It's not 28nm it's 14nm
14nm for SoC and 14nm for PoP
PoP is new technology for smartphones.
Its storage and RAM memory on same single chip
So SoC is still on 14nm!!!!

" 600 series never uses powerful high end cores. "

go get your facts straight ...

Exactly, not only that. A72 cores are planned for 14/16nm FinFet, I doubt they can use them in 28nm and stay on the TDP of the smartphone SoCs.

And if its true then I'll skip SD615 for SD620 as it seems better than the first.

You have to be far far far beyond utterly clueless to even consider this as real.

Lol... It will be strange if Snapdragon 620 outperforms 820...

Hope this is gonna be the midrange chipset of 2015, insead of 410

This info is accurate because Qualcomm is developing TS2 cores which is next generation of Krait
