M2 vs. M3 vs. M4 MacBook Air Buyer's Guide: 25+ Differences Compared

Apple just announced a new MacBook Air, introducing its latest chip, an enhanced camera, and a striking new color option. Simultaneously, it discontinued the two previous generations. So how does the new model compare?

Before the introduction of the latest model, the 13-inch M3 MacBook Air started at $1,099 and the 15-inch model started at $1,299. The 13.6-inch ‌MacBook Air‌ with the M2 chip from 2022 remained in the lineup at a price of $999. Now, the 13-inch M4 model starts at $999. It is also worth remembering that it is possible to shave at least $100 off the price of a new ‌MacBook Air‌ directly from Apple with education pricing.

The main upgrade offered by the three ‌MacBook Air‌ models are their chips. In benchmark tests, the M3 outperforms the ‌‌M2‌‌ by about 17% in single-core tasks and approximately 21% in multi-core tasks. In GPU performance measured by Metal benchmarks, the M3 exhibits a notable improvement of around 15% over the ‌‌M2‌‌. The M4 outperforms the M3 by about 25% in single-core tasks and 30% in multi-core tasks. In GPU performance, the M4 offers improvement of around 21% over the ‌M3‌.

There are a number of other notable differences between the three ‌MacBook Air‌ generations beyond their chips. While these upgrades are fairly small, they are worth bearing in mind when contemplating whether to get the latest model, or a used or refurbished unit for a lower price.

Read on to find out about all of the differences between the ‌M2‌, M3, and M4 ‌MacBook Air‌ models to help you decide which model will suffice for you, as well as if it may be worth upgrading.

Overall, the M3 and M4 MacBook Airs represent minor upgrades over their predecessors, largely focusing on enhanced performance rather than new capabilities. Their main target audiences are those who have an older ‌MacBook Air‌, such as an ‌M1‌ or Intel-based model, or no ‌MacBook Air‌ at all.

Unless you can leverage the specific advantages of the M4 chip and require maximum performance from its highly portable form factor, it is likely not worth buying the M4 ‌MacBook Air‌ over the previous ‌MacBook Air‌ for most users, providing you can get it for a good enough price.

However, if future-proofing is a major priority because you tend to keep your computer for many years, the extra cash to get the latest model will probably be warranted. The M4 model's significantly improved camera and enhanced support for two external displays may also justifiably swing your buying decision if you make a lot of video calls or have multiple monitors.

It is certainly not worth upgrading from the ‌M2‌ or M3 to the M4 ‌MacBook Air‌ for the overwhelming majority of customers. Upgrading from an ‌M2‌ 13-inch ‌MacBook Air‌ to an M4 15-inch ‌MacBook Air‌ may be more justifiable owing to the display size increase, but there is little that the latest generation meaningfully offers over its predecessor. The two older machines are still highly capable.

Great chart. I agree, the M2 is still more than capable. I will look forward to upgrading once the transistor count is double what I have now, that should be a considerable and noticeable performance increase....which will take me another 1-2 years.

"Support for up to two external displays when the lid is open"

Does this mean the internal display is also available or is it off? Also interested if the M4 delivers better/same/worse battery life over the M2/M3.
M2: One external display
M3: Two external displays in clamshell mode, one with laptop open
M4: Two external displays

it’s been a while since I got a new Mac, but will these support 2 external monitors?
I guess you didn't read the article. :confused:

which is why they should have released the MBA with an M5 in the spring, which will be a more significant jump than the M4.
You keep saying the M5 in the spring like it's a fact, it's not..it happened one time (releasing an M chip in the spring), and during a 3nm fab change that Apple was in a hurry to move away from as it was expensive and low-yield.

I don't think we will see another until WWDC at the earliest, but likely with the Pro model releases in the fall. Either way, you're speculating.
