I have heard about Intel M but not that much honestly and I see that people still continue to work on the models with i3 and i5 and i7 even lately. So concentrate on those and forget about that machine you really have here anyway. Good luck.
Current days I would simpy go with for example something like I am not sure but probably mobile Ryzens, correct ? It seems to me they really do the job just fine. See my point ? Intel is overpriced now. So let's make it happen. Let us know how much.
