My MBA 2017 has a nice i7 that works for my use and could get a bit more life out of it if it had more RAM, as the model was only available from Apple with 8gb memory at the time. Getting 16gb to work would take past what it was made with, but as it it standard components, and Intel, it should work or?
I would get someone better at soldering than me to do it. :-D
