iFixit at present shared a teardown overview of the brand new MacBook Air and MacBook Professional, giving us a peek at what’s beneath the hood. For essentially the most half, these machines look the identical as older Intel MacBooks inside, however there are a number of highlights.
The removing of the fan is the most important change to the MacBook Air, with the fan having been changed by an aluminum spreader positioned to the left of the logic board.
A thick chilly plate over the M1 processor attracts warmth through conduction to its flatter, cooler finish, the place it may well safely radiate away. With no fan, this resolution might take longer to chill off, and will cap out sooner, however by foregoing heatpipes or a vapor chamber, the sink additionally has extra mass to saturate with thermal vitality. There are not any transferring components, and nothing to interrupt.
Apart from a brand new logic board and cooler, the within of the MacBook Air is equivalent to its predecessor, and iFixit says that restore procedures “will possible stay virtually completely unchanged.”
As for the MacBook Professional, it is so much like the prior mannequin that iFixit needed to double test to ensure an outdated MacBook Professional hadn’t been by chance bought.
iFixit anticipated to see some consolidation of MacBook components and design, however the cooling setup is much like what’s seen in Intel MacBook fashions. The fan, in reality, is equivalent to the fan within the 2020 13-inch MacBook Professional launched earlier this yr.
Whereas the internals of the MacBook Air and MacBook Professional are near equivalent to their Intel counterparts, iFixit did check out the all-new M1 chip, which is the shiny silver bit with an Apple emblem. Subsequent to the chip, there are small silicon rectangles which might be Apple’s built-in reminiscence chips.
iFixit says the built-in reminiscence is “barely devastating” as a result of it makes repairs on the M1 Macs a lot more durable. Observe that there is no Apple-designed T2 chip within the M1 Mac fashions as a result of the T2 safety performance is built-in proper into the M1 chip.
iFixit says that whereas these appear to be superficial adjustments, they’re an expression of “years of intense work” with “hints of much more to return sooner or later.”
