The Xiaomi Mi Note 2, which has been the subject of several rumors and leaks so far, will have a variant that'll be powered by Snapdragon 820 SoC and come with 4GB RAM, according to a latest rumor out of China. In addition, the rumor says that there will also be a top-end version with Snapdragon 821 chipset and 6GB RAM, something which has been already revealed by a recent leak. While the SD820 variant will have 32GB internal memory, the SD821 model will offer 128GB storage. Needless to say, none of this has been officially confirmed yet, so take it with a pinch of salt. Via
