Is there a comparison between Snapdragon 400 and Snapdragon Wear 2100 SOC?

Hi guys!

I haven't found any performance and efficiency comparison between the two SOCs used in the 2nd and 3rd generation of smartwatches.
Does anyone know of one? I'm very curious to know if the 25% efficiency gains claimed by Qualcomm is true or not.

Cheers
