Samsung is planning to start creating Next Generation 10nm chips, and there is no surety that will it prepare the Snapdragon 845 or no as TSMC is also planning the same.
Currently, Samsung is developing the Snapdragon 835 chipset, a 1st generation 10 nm process, and the one it is planning to develop will provide 10% increase in the performance.
