Chosen Solution
I have an early 2015 Retina Macbook with a 1.1 GHz Dual-Core Intel Core M logic board. Is it possible to upgrade it to the 1.4GHz Core i7 Logic board from a 2017 Macbook?
There are enough differences which make this very iffy! I don’t know of anyone even attempting this. Given the costs and risks I think it’s just cheaper to snag a used system it the processors speed is such an issue. Even still the performance gains are not that sizable, remember this CPU is thermally limited.
