If you remember yesterday information about LeEco Le 2S on GFXBench then today I have good info: on Ludashi (another benchmark) was tested version with Snapdragon 821.
What this means one of two things: eather LeEco isn't 100% sure which SoC to put into the model or (what is more probable) there will be two versions of Le 2S (probably one with SD821 will be named 2S Pro).
