Apple M1-powered MacBook Air and MacBook Pro are identical from the inside out, says iFixit

In this news, we discuss the Apple M1-powered MacBook Air and MacBook Pro are same from inside, says iFixit.

MacBooks equipped with an Apple M1 chipset are now available for purchase in select markets. This is a drastic change from the previous generation MacBooks, but you won’t see it on the surface because it’s internal. The M1 chip replaces the Intel chipset which Apple claims is revolutionary in the PC world. Most critics point out that the M1 chip responds to these claims, in fact pushes the limits for how quickly a laptop can become. It gets even more fascinating to know this, thanks to the latest revelations from the folks at iFixit who performed complete teardowns of the latest MacBook Airs and MacBook Pros.

In their respective teardowns, one of the main points about MacBook Air and MacBook Pro was that they aren’t much different from each other. Of course, the biggest difference between the two MacBook models is the fan Pro has, but Air lacks one. And that difference has more to do with performance than the size and bulkiness of these MacBooks. According to iFixit, the fan’s place has been replaced with an aluminum heat sink that hangs from the motherboard to dissipate heat generated by the processor.

iFixit noted that this system works great for the MacBook Air but, in turn, introduced a performance cap which is something MacBook Pro can pass because it has a fan. “There just isn’t much to do here. A thick cold plate on the M1 processor draws heat by conduction to its flatter, cooler end, where it can radiate safely. Without a fan, this solution may take longer to cool down, and may get clogged sooner, but by avoiding heat pipes or a steam chamber, the sink also has more mass to saturate with thermal energy. There are no moving parts and nothing to break. You’ll need new thermal paste every now and then, and that’s about it, ”iFixit noted in its teardown report for MacBook Air.

The MacBook Air is also a bit different from its Intel-based predecessors. The battery is different in size from its previous counterpart, as well as the placement of some other components. But the overall repair process for the MacBook Air equipped with the M1 will remain “almost completely unchanged.” This means that the MacBook Air will be repaired using the same method that Apple engineers used for Intel MacBooks. Apple will likely charge the same fees for repairs as it does for Intel-based MacBooks, in case the warranty expires.

The MacBook Pro, on the other hand, has the privilege of letting the fan cool its innards when it’s warm while handling heavy workloads. The fan, however, is no different from the one fitted inside the predecessor. There was speculation that the MacBook Pro’s fan would be quieter than its previous model, but that’s not the case.

According to iFixit, “The M1 MacBook Pro’s single fan is identical to the 2020 Intel dual-port MacBook Pro fan we purchased earlier this year. Not similar – identical. “But while this is true, the fan does have some attenuated noise and this is due to the fact that the Apple M1 chipset is quite capable of handling maximum workloads without generating a lot of heat.” Remember that that same M1 chip works well in the fanless MacBook Air, so that fan probably doesn’t have much going on, even under prolonged load. “

The superstar, the M1 chip, looks like how Apple has displayed it in several promotional materials. It is a 5 nanometer processor that features an 8 core design, four of which are reserved for performance cores and four for efficiency cores. The memory chips used with the M1 chip are similar to those in recent iPad models. “If this sounds familiar to you, it might be because you saw one of our recent iPad teardowns. It’s no surprise that Apple copied some of its own homework here. By integrating RAM into the M1 package, each part of M1 (CPU, GPU, Neural Engine, etc.) can access the same memory pool without having to copy or cache the data in more than one place ”, iFixit noted in its teardown.

But while several things are hunky-dory, Apple hasn’t made these memory modules accessible to users. This means that they will be replaced with the processor and there is no way to extract them from the complete module. But this is something Apple could fix in the future. This is the first generation of ARM chipsets from Apple. Intel’s transition to M1 itself will take around two years and that’s a lot for Apple to tackle some things that could be in its favor.

Apple recently released its own ARM-based M1 chipset that powers the MacBook Air and MacBook Pro.

News Highlights:

  • Apple’s MacBook Air and MacBook Pro are no different from the inside.
  • The MacBook Air doesn’t have a fan inside, but the Pro does.
  • The M1 chipset has a memory module similar to that of the iPad.
