You have a decently powerful laptop CPU, I have the same one in my Razer Blade.
64GB of memory is surprisingly affordable for it, I think I paid less than 220 Euro in total for two 32GB Modules. (HyperX I think)
Make sure you buy 2667 Memory, since most laptops can't run XMP profiles so they will run the JEDEC profile that is default for the kit.
(What I mean is, there is a risk that if you buy faster memory, 2933 or 3200, it will run even slower because it could default to 2133 or 2400).
Tom and Maru said everything, more memory doesn't make laptop faster but it helps you run more tasks and bigger scenes. 64GB is good minimum today, even for laptop.
