Compared: MacBook Air with M2 vs 2022 13-inch MacBook Pro

We have both M2 Macs here in our testing studio. We're comparing the M2 MacBook Air against the M2 MacBook Pro to see how they stack up and how much of a difference the thermal limitations make.

Apple's introduction of the M2 generation of Apple Silicon is similar to the M1 launch in a few ways. Yet again, Apple is starting with entry-level Mac models, with the M2 MacBook Air and M2 13-inch MacBook Pro the first options on the block.

However, rather than being a simple spec-bump to consider, Apple has added a giant wrinkle to proceedings by overhauling its MacBook Air.

The wrinkle doesn't make the decision-making process harder. Indeed, the changes Apple made have made it much easier to recommend one over the other.

What it does do is make it harder to justify using the other.

Specifications

Very different exteriors

In the M1 generation, there were few distinct differences between the 13-inch MacBook Pro and the MacBook Air, and they boiled down to weight and physical dimensions, thermal throttling, and that's about it. Specifications-wise, they were pretty close, making you think about going for one model over the other.

For the M2, Apple's decision to revamp the MacBook Air introduces many variations between the two models.

MacBook Air vs MacBook Pro thickness

Externally, the update of the MacBook Air brings it more in line with the 14-inch MacBook Pro and its 16-inch counterpart, with a flatter appearance instead of its signature taper. The 13-inch MacBook Pro still looks the same as the previous generation.

The two are pretty similar in terms of footprint, with each being 11.97 inches wide, but the Air is slightly deeper at 8.46 inches to 8.36 inches for the Pro. The thickness difference is still considerable at 0.44 inches for the Air, and 0.61 for the Pro, with the Air also lighter at 2.7 pounds to 3.0 pounds.

MacBook Air display versus MacBook Pro

Opening up the two, you have similar but different displays. The Air's screen is larger at 13.6 inches than the Pro's 13.3 inches, with the Air being slightly taller. That also comes across in the resolution of 2,560 by 1,664 pixels for the Air and 2,560 by 1,600 for the Pro.

Both are equally bright at 500 nits, with Wide color (P3) support and True Tone.

However, while the 13-inch MacBook Pro has a larger bezel space at the top to place its FaceTime HD camera, the MacBook Air goes for a thinner bezel but uses a notch instead.

This design aesthetic could be a deal-breaker for users, but one used on most other MacBooks Apple sells. It's also relatively unobtrusive, as you're still getting the same size and resolution as the Pro for full-screen apps, since Apple blacks out the display "ears" around the notch.

That camera's also better on the MacBook Air, as Apple uses a 1080p FaceTime HD camera instead of the 720p in the Pro. Both benefit from advanced image signal processing, providing computational video adjustments.

MacBook Air keyboard versus MacBook Pro

The keyboard is also different, but more from the 13-inch MacBook Pro continuing to hold onto the Touch Bar. The Air instead uses full-height function keys and a dedicated Touch ID button.

Rounding out the outside, both models have a pair of Thunderbolt/USB 4 ports and headphone jacks with support for high-impedance headphones, except that the MacBook Air also has a MagSafe 3 charging port.

MacBook Air and MacBook Pro ports

Speaking of audio, the MacBook Air has a four-speaker system with wide stereo sound and support for Spatial Audio, while the Pro has stereo speakers. Each also has a three-mic array with directional beamforming for getting audio back into the Mac.

Internal differences

While the outside is different, you could expect the internal specifications to generally be the same. To a point, this is true, but even here, there are some differences.

Both machines sport an M2 processor

The headline addition, the M2, has an 8-core CPU consisting of four high-performance cores and four high-efficiency cores, which Apple says provides an 18% improvement over M1's version.

There's a memory bandwidth boost to 100GB/s, while Unified Memory capacities have expanded from 8GB and 16GB options to include a 24GB variant.

Then there's the Neural Engine, which benefits from a 40% performance boost. M2 also gains the Media Engine, a hardware video encoding and decoding component for handling H.264 and HEVC video, and ProRes 4K and 8K footage.

The difference in how M2 is implemented across the MacBook Air and the 13-inch MacBook Pro revolves around the GPU.

The 13-inch MacBook Pro has only one M2 configuration, where it uses a 10-core Apple-designed GPU. The MacBook Air provides two options: the 10-core joined by an 8-core alternative.

This difference may seem slight, but it's enough of a change for Apple to warrant the cost difference between 8 cores and 10 cores to be $100.

A connected performance difference is that the MacBook Air is passively-cooled, while the 13-inch MacBook Pro includes an active cooling system. This means the MacBook Pro can better handle sustained high-effort workloads for longer than the MacBook Air before succumbing to thermal throttling.

Let's see what that translates to in terms of real-world usage and performance benchmarks.

With the typical Geekbench 5 CPU test, the MacBook Air scored a 1909 single-core and an 8547 multi-core. The MacBook Pro eked out slightly higher scores with 1941 and 8966 on the single and multi-core respectively.

In this shortened test, we see the fans do slightly boost speeds of the MacBook Pro, though not by much. Especially when you look at the single-core score as most actions on your Mac are single-core. In use, they feel equally as snappy.

Cinebench R23 results

We don't start to see significant differences until we moved to our sustained performance benchmarks. We perform this by running Cinebench R23 repeatedly back-to-back which maxes out the CPU. At the same time, we monitor the fan speed — on the MacBook Pro, CPU temperatures, and CPU frequency.

In total, we ran Cinebench R23 a total of eight times, taking nearly an hour and a half to complete. We logged the CPU temperature and frequency at the end of each run and what its multi-core score was.

On our first run, we got similar scores. The Air 8,210 and the Pro got 8,636. A single running of Cinebench is only slightly representative of a typical workflow that may speed up the CPU for a period of time, but at ten minutes per-run, it is still more than most tasks.

M2 speed over time

As we kept the CPU maxed out, the MacBook Pro's score kept static, hovering around 8,600 the entire time with a consistent internal temperature of 214 degrees Fahrenheit and CPU speed of 3.2GHz. To keep it cool, the fans ramped up to 3500 to 4000 RPM.

M2 temperatures over time

This means that even after an entire hour of 100 percent CPU utilization, the fans were able to adequately cool the machine enough to not take a performance hit.

Cinebench R23 scores over consecutive runs

The MacBook Air, however, didn't fare as well. At about the halfway mark the MacBook Air reached a toasty 226 degrees Fahrenheit and performance started to drop. By the end, the CPU was only running at 2.6GHz and the score had dropped to 7529.

It appears Apple had to dramatically reduce the speeds of the M2 to prevent overheating, dropping the temp to 208 Fahrenheit on the last run.

The good news here is that this test is not at all emblematic of real-world usage. The MacBook Air is able to be nearly as fast as the MacBook Pro in all the ways that it matters. It is only after pushing the CPU to its limits for an incredible amount of time did we see the performance take a hit.

Nobody buying the MacBook Air will have any workload that pushes the CPU to 100 percent for this long. Even a few-second break allows the CPU to cool back to acceptable levels and performance to rise.

Simply put, there is no need to worry about the thermal limitations of the MacBook Air. It's a non-issue for the Air's target audience.

Users with more demanding needs may look towards the 13-inch MacBook Pro as a possible answer, but you could just as quickly point those customers in the direction of the M1 Pro or M1 Max-equipped 14-inch and 16-inch MacBook Pro if performance is required.

Another internal difference is power, with the MacBook Air packing a 52.6-watt-hour lithium-polymer battery against the 58.2-watt-hour version in the 13-inch MacBook Pro. The Pro has better battery life against Apple's metrics, equating 17 hours of wireless web usage to 15 hours on the Air, or 20 hours of Apple TV app movie playback against 18 hours.

That's a difference, but it's not a massive issue, as it shows both are equally capable of surviving a day of work.

Is the 13-inch MacBook Pro an option?

In an article about which M2-equipped MacBook to buy, you would expect more conflict about which model is the best for most users. That certainly isn't the case here.

13-inch MacBook Pro

On the one hand, you have a modernized MacBook Air that has a better display, improved speakers, an extra chip option, and lightness in its favor while still providing similar levels of performance. Conversely, you have an older-design MacBook Pro that offers very few benefits.

Those benefits are small, such as having a longer battery life and active cooling versus passive cooling. Sure, it will be able to do more demanding tasks for longer before thermal throttling strikes, but it will not be a factor for most of the target audience of Apple's value-oriented MacBook lineup.

There's little else to stretch for in advantages, though people who may be annoyed by the notch staring at them on the display or really love the Touch Bar may want to seek out the 13-inch MacBook Pro over the Air.

Indeed, if you look at the two at a comparative-specification level, they are, in fact, the same price across the board.

Users who don't anticipate workloads that could benefit from 10 GPU cores instead of 8 cores could save themselves $100 by going for the cheaper chip option, making the Air even more attractive.

There are reasons to go for the 13-inch MacBook Pro over the MacBook Air. They happen to be oddly specific ones.

What M2 MacBook should I buy?

Except for those who have the aforementioned specific reasons to get the 13-inch MacBook Pro, the MacBook Air is probably going to be the focus of your attention.

At the value end, the base-model MacBook Air costs $1,199, with the 8-core GPU version of the M2, 8GB of Unified Memory, and 256GB of storage. You can pay $100 more for the 10-core GPU version, which gives you the same base specifications as the identically-priced 13-inch MacBook Pro.

On either device, going from 8GB to 16GB of Unified Memory costs an extra $200, then another $200 on top to get to 24GB.

For storage, going from 256GB to 512GB will cost an extra $200. From 512GB to 1TB, it's $200 more, and a further $400 from 1TB to 2TB.

As AppleInsider has previously discussed when buying a MacBook, storage is a killer on the wallet. Given the numerous fast external drives you can acquire for a reasonable price, it may be worth considering going down that route and living with an extra element to carry around than paying out a high storage upgrade fee.

For storage, you should get what you are comfortable using at the very minimum. External drives could be a better option if you want to go higher.

Since you cannot upgrade any components after purchase, storage is also the only relatively upgradable section via external drives.

You'll be stuck with the GPU core count and memory from the time of purchase until you replace the MacBook. Therefore, it is typically best to invest more in memory and the GPU before increasing storage.

In the case of the MacBook Air, AppleInsider recommends going for the 16GB memory upgrade at first since that can impact general performance as well as the graphical. The $100 chip update could be helpful to get, but it won't be as beneficial as more memory.

Four colors of the new MacBook Air

After the 16GB memory upgrade, it's a toss-up between the 24GB memory option or upping the storage to 512GB, but the latter may be more prudent on a quality-of-life basis. However, getting the 24GB memory upgrade and the chip update (if applicable) is strongly recommended instead of getting the 1TB SSD.

Above all else, you should buy based on your needs, but you should also consider other options than just M2, especially if you want more performance.

For example, pricing out a 10-core GPU M2 MacBook Air or 13-inch MacBook Pro with 16GB of memory and 512GB of storage costs $1,699. For just $300 more, you could use the M1 Pro-equipped 14-inch MacBook Pro with the same memory and storage (find the best sale price).

That upgrade doesn't just get you a bigger screen but also an 8-core CPU with six performance and two efficiency cores, a 14-core GPU, 200GB/s of memory bandwidth, and a bunch of extra ports on the sides. If your bank account can stomach it, there's also a lot more headroom for upgrades.

The 13-inch MacBook Pro could be considered an answer for those needing performance, but it's far from being the best option.
