At least two Lumia Flagship devices are under testing but don’t expect these coming out before Q3 in 2016. Qualcomm has recently released its Snapdragon 820 processors to manufacturers and Microsoft is one of the vendors keenly evaluating it for its future devices. With Lumia 950 and Lumia 950 XL, Microsoft introduced liquid cooling to handle processor heat generation. Expect advanced cooling technology on Snapdragon 820 running 2016 Flagships.
Snapdragon 820 will feature custom, 64-bit CPU core, known as Kryo. The chip is manufactured on an advanced 14nm process. The GPU Adreno 530 will be 40 percent faster than the Snapdragon 810’s Adreno 430 GPU.
