MacBook Air M5 vs M4: compare the configuration, not just the chip.
Compare 13-inch M5 and M4 MacBook Air configurations, storage choices and the reasons to upgrade or keep your existing laptop.
By CrowCatch · Researched comparison; not hands-on testing. Updated .
The short answer
Start with equivalent memory and storage. An M4 offer with less storage is not a like-for-like alternative to the M5 configuration above. If you already own an M4 that runs your applications satisfactorily, the announcement of another chip is not itself a reason to replace it. For a first purchase, choose between actual configurations and purchase conditions, rather than assigning a fixed value to one generation of difference.
| Decision point | 13-inch MacBook Air M5 | 13-inch MacBook Air M4 (2025) |
|---|---|---|
| Configuration compared | 16GB memory / 512GB SSD | 16GB memory / 512GB SSD, configured option |
| Entry storage context | Apple currently lists 512GB | Apple's model specification starts at 256GB |
| Purchase question | Is the newer configuration useful for your work? | Is a comparable configuration available on suitable terms? |

Who this comparison is for
This is for shoppers considering the 13-inch Air for everyday work, study and travel. It is not a comparison with a 15-inch Air or a MacBook Pro. Retailer listings can combine multiple configurations, so keep the selected screen size, memory and SSD capacity visible while comparing. Check your required applications and peripherals separately; the right computer is the one that supports the complete workflow.
When the M5 deserves a closer look
Consider the newer model when its exact configuration, warranty and support arrangements fit your needs. Evaluate any manufacturer performance claim in its stated workload and configuration, rather than treating it as a measurement of your applications. CrowCatch has not benchmarked either laptop. If performance is the purchase reason, seek independent measurements of the configurations you are actually considering.
When an M4 can remain a sensible option
An M4 can deserve consideration when a comparable configuration is offered with acceptable condition, seller, warranty and returns. We have no approved live offer to establish a saving here. For an existing owner, identify a concrete limitation first: storage, memory, application support or the external-display setup. If no limitation is affecting your work, keeping the current machine avoids a migration that does not solve a defined problem.
The total-cost comparison
Write down the computer configuration, required adapters, display connections, included charger and any migration costs. Compare new, refurbished and open-box units separately. An apparently lower purchase price can come with different return or warranty terms. Conversely, spending more on a newer model does not guarantee that a missing port or incompatible application is resolved.
Before deciding
Save the exact retailer configuration and compare it with Apple's model-specific documentation. Check current software requirements and evidence for any performance-sensitive task. Our conclusion is conditional: configuration and workflow come first; the chip name is one part of that decision. No current retailer price, stock claim or hands-on verdict is implied.
