💻 MacBook Air 13: M5 vs M4 vs M3
AI-powered analysis across 41 matched specifications
MacBook Air 13" (M3)
Apple
Overall Score
Best treated as the fleet to retire first: a still-capable fanless ultraportable for light office work, but 8 GB base memory, a 1080p webcam and the single-display-with-lid-open limit make it the weakest residual-value choice for new UK rollouts.
MacBook Air 13" (M4)
Apple
Overall Score
Best value buy for cost-conscious UK fleets sourcing carry-over or refurbished stock: 16 GB base memory, a 12 MP Center Stage camera and dual external-display support at a £999 entry price cover the vast majority of knowledge-worker roles.
MacBook Air 13" (M5)
Apple
Overall Score
Best for new standard-issue deployments and any role using Apple Intelligence, on-device LLMs or Wi-Fi 7 offices — the current generation with the longest macOS support runway and strongest resale position over a 3-year cycle.

Expert Analysis
AI-assisted analysis based on published specifications
These three MacBook Airs share an identical fanless 1.24 kg chassis, the same 13.6" 500-nit Liquid Retina display and the same 18-hour battery rating, so the upgrade case again lives entirely inside. The M3 is the one to plan around: it shipped with just 8 GB of starting memory, a dated 1080p webcam, only 100 GB/s memory bandwidth and a single-external-display limit with the lid open — all of which make it the weakest fit for modern hybrid work. The M4 was the pivotal refresh, doubling base memory to 16 GB, adding the 12 MP Center Stage camera, enabling dual external displays with the lid open and — crucially for fleet budgets — arriving at a lower $999/£999 starting price than the M3 it replaced. The M5 then adds per-GPU-core Neural Accelerators for roughly 8× the on-device AI throughput of the M1, more memory bandwidth and Wi-Fi 7 / Bluetooth 6 via Apple's new N1 chip, but for mainstream Office, Teams and browser work it feels much like the M4 in day-to-day use. For UK knowledge-worker fleets: retire 8 GB M3 Airs at the next cycle, treat M4 Airs as excellent value that can run on, and standardise new standard-issue purchases on the M5 — specifying 16 GB as the floor and 24 GB for developers, since unified memory cannot be upgraded after order.
MacBook Air 13" (M3)
Best treated as the fleet to retire first: a still-capable fanless ultraportable for light office work, but 8 GB base memory, a 1080p webcam and the single-display-with-lid-open limit make it the weakest residual-value choice for new UK rollouts.
MacBook Air 13" (M4)
Best value buy for cost-conscious UK fleets sourcing carry-over or refurbished stock: 16 GB base memory, a 12 MP Center Stage camera and dual external-display support at a £999 entry price cover the vast majority of knowledge-worker roles.
MacBook Air 13" (M5)
Best for new standard-issue deployments and any role using Apple Intelligence, on-device LLMs or Wi-Fi 7 offices — the current generation with the longest macOS support runway and strongest resale position over a 3-year cycle.
