For day to day use CPU technology has come to a crawl.
Stuff like opening apps, sending texts and web browsing you're most likely not going to see much of a difference.
For gaming and coding, yes there will be a difference at play.
At the end of the day I ask myself "How much faster can Facebook open?!"
Side by side to an S7Edge it is barely a difference in those type of apps.
Literally a hair faster in favor of the S7Edge.
Then again, my phone is rooted and "optimized", so it's not really a fair comparison.
Still holding on to the Note 4, though.
