We'll leave it to you to decide whether a jump is worth it, given that there is no production node improvement, and both chips are done at 10nm, albeit with the second generation of theprocess that is always the more refined, and offers higher performance with a lower power draw.
Qualcomm claims that "our new Spectra camera and Adreno graphics architectures boost power efficiency by up to 30 percent compared to our previous generations," so we should notice significant battery savings when performing graphics-intensive tasks or video capture with Snapdragon 845 devices compared to 835 gear.
