The Galaxy Note 6 is expected to be pretty powerful; that conclusion has been drawn because rumoured specs for the Lite version of the device put it on a par with the Galaxy S7.
The Galaxy Note 6 Lite, according to a Weibo post by Rec2020_Eight, will feature a 5.8-inch screen, a Snapdragon 820 processor, and 4GB RAM. That's the same chip and RAM found in the Galaxy S7, which is one of the most powerful handsets on the market.
The regular Galaxy Note 6, meanwhile, is rumoured to feature a Snapdragon 823 processor and a whopping 6GB RAM.
These specs are far from official though; the poster has previously posted about the Sony Xperia X Premium and standard Galaxy Note 6, but these aren't out yet so they don't have an established track record.
