New range of Apple MacBooks ditched Intel in favor of Apple’s new M1 system on chips (SOC). On the outside, they look eerily like the classic Intel MacBook. If you are wondering what has changed inside, our friends at iFixit ripped new notebooks. It’s the stuff that isn’t there that might surprise you.

For example, the MacBook Air doesn’t have a fan at all. On the positive side, getting rid of the fan means the machine is running completely quiet. However, removing it didn’t add more battery as some might have hoped. Instead, Apple added a heat sink to help keep the machine cool.

At first glance, not having a fan might seem like a downside, but you have to remember that Apple’s iPhones and iPads have been kicking performance for quite some time now and neither are fans. more present. With the amount of performance you get from this machine, you could potentially throw away your old laptop.

On the other hand, you think the MacBook Pro would feature a completely different cooling system, based on early reviews. You are wrong. iFixit has found that the fan used in the M1 Pro is exactly the same as that found in the latest generation Intel model. But, thanks to the much better efficiency of Apple’s SoC, the fan doesn’t spin as often. And when it does, it’s a silent whisper.

Both laptops use the same M1 chip, but Apple uses a method called “binningTo differentiate his inferior machine. To put it in simple terms, all M1 chips have eight GPU cores, but some of them have an eighth core that either isn’t fully functioning or is not up to Apple’s standards. So instead of just throwing them away, the company just deactivates the eighth core and ships it as a seven-core model. This is why there is a version of the MacBook Air with a seven-core GPU while all other models have eight.

Of course, none of these laptops were upgradeable in the past and that doesn’t change suddenly because of M1. This means that you will have to be very careful with what you buy when you first order your computer. What you see is what you get. And this time around, you won’t have a choice of processor and the RAM is built right into the SoC. All you can choose from is storage and memory, which are capped at 2TB and 16GB respectively.

As always, iFixit does a masterful job of tearing up the latest gadgets and giving us an idea of ​​how difficult it is to fix and what has changed. Discover the complete disassembly to see side-by-side comparisons of the MacBook’s new internals with Intel models.
