This video (use close captioning) shows how the iphone 8 plus may be milliseconds to seconds faster loading games than the note 8 while the Note 8 kills the iphone 8 plus in terms of ram management. The note 8 was able to hold all of the games in the ram which was really impressive while the iphone 8 plus had to constantly reload.
The Note 8 is a multitasking beast. I prefer good ram management over a game loading faster since that is required in the real world. For those who said iphone didnt have a ram problem and that they dont need more ram, this doesn't look too pleasing. Expect these same type of results or worse with the iPhone X since it has the same 3 gb ram and uses additional ram to run Face ID.
