Looks like the Qualcomm 205 is a pin compatible replacement for the Snapdragon 210/212, whereby they figured out they could trim out a few hardware chunks (H.265 decoding & 8MP camera support) and save on manufacturing (smaller dies) and licensing costs. Plus, this cheaper chip can be dropped into phone designs from 2014 (Snapdragon 210) and 2015 (Snapdragon 212) with little to no engineering or software work. Seems like a great way to reuse tested cheap phone designs without additional cost or delay in getting products to market.
