The MacBook Pros have long used a codename MacBookProX,Y
.
Apparently the X
refers roughly to a generation. One generation can possibly span more than one "early", "middle", "late" period of one year, or indeed may span more than one year.
The Y
seems to distinguish screen size. It used to be that the Y
increased with screen size. Nowadays that pattern no longer holds.
Some examples:
MacBook Pro "Core i7" 2.2 15" Touch/2018 ... MacBook Pro "Core i9" 2.4 15" Touch/2019
MacBook Pro "Core i5" 2.3 13" Touch/2018 ... MacBook Pro "Core i7" 2.8 13" Touch/2019
MacBook Pro "Core i7" 2.6 15" Touch/2018 Vega ... MacBook Pro "Core i9" 2.4 15" Touch/2019 Vega
MacBook Pro "Core i5" 1.4 13" Touch/2019 2 TB MacBook Pro "Core i7" 1.7 13" Touch/2019 2 TB
What does the MacBookProX,Y
codename mean? In particular, and now that the logic board is entirely monolithic, but at least still replaceable, not glued, does the codename mean that one "chassis" (keyboard + screen) fits precisely boards of the same codename?
