MacBook Air M5 Benchmarks: How Much Faster Is It Really?
The MacBook Air M5 vs M4 UK benchmark comparison is where the new Apple M5 chip performance becomes clear. Early MacBook Air M5 benchmarks show measurable gains in CPU speed, GPU rendering, and AI processing compared with the previous generation. While the chip architecture is broadly similar, both feature 10-core CPUs with four performance cores and six efficiency cores, the M5 achieves measurably higher clock speeds and substantially improved memory bandwidth, which flows through to real-world results.
Geekbench 6 CPU Scores
Independent testing from TechRadar and Tom’s Guide running Geekbench 6 on both laptops side by side reveals a clear generational improvement:
| Test | MacBook Air M4 | MacBook Air M5 |
|---|---|---|
| Single-Core Score | ~3,800 | ~4,400 (+15–16%) |
| Multi-Core Score | 14,921 | 17,276 (+16%) |
| GPU Metal Score | ~55,000 | ~76,000 (+38%) |
| CPU Clock Speed | 4.41 GHz | 4.46 GHz |
| Handbrake 4K→1080p | ~4 min 54 sec | ~4 min 34 sec (20 sec faster) |
The GPU gains are particularly striking. The Metal score jump from approximately 55,000 on the M4 to around 76,000 on the M5 represents a 38% improvement, far outpacing the modest CPU uplift. This is largely attributable to the Neural Accelerator embedded in each GPU core, a new architectural addition that also turbocharges AI processing.
AI Performance
Apple’s own testing (conducted in February 2026) demonstrates the M5’s AI capabilities are on another level compared to its predecessor:
- Up to 4x faster AI task performance vs MacBook Air M4
- Up to 9.5x faster AI task performance vs MacBook Air M1
- Up to 1.9x faster AI video enhancement in Topaz Video vs M4
- Up to 1.5x faster 3D rendering with ray-tracing in Blender vs M4
- Up to 1.5x faster image processing in Affinity vs M4
For context, Apple’s claim of 4x faster AI performance is measured against a 32GB M4 configuration; a premium SKU. For the 16GB base MacBook Air M5 vs M4 UK comparison, the practical gains in everyday AI-assisted workflows are still substantial, particularly for Apple Intelligence features, on-device LLMs, and AI-powered photo or video editing tools.
SSD and Storage Speed
One of the most overlooked upgrades in the MacBook Air M5 is how much faster the storage is, not just how much more of it there is. Reviewer testing from Six Colors found read speed improvements of 125% and write speed improvements of an extraordinary 219% compared to the M4 model when measured with Blackmagic’s disk speed tool. A second test with AmorphousDiskMark produced improvements of over 250% in some cases. This will be immediately noticeable for anyone who works with large files, exports video, or migrates data between drives.
Battery Life
Battery life is one area where the MacBook Air M5 does not improve on the M4 and in some specific tests, shows a slight regression. NotebookCheck’s lab measured 16 hours and 11 minutes in a WLAN test at 150 nits of brightness, compared to 16 hours and 13 minutes for the M4. At full brightness, the M5 lasted 6 hours and 39 minutes versus 7 hours and 5 minutes on the M4. Both laptops share the identical 53.8 Wh battery, meaning Apple has maintained, rather than improved battery life while delivering meaningfully better performance.
The 512GB Base Storage: Why This Matters for UK Buyers
Perhaps the most immediately practical upgrade in the MacBook Air M5 is the doubling of base storage from 256GB to 512GB. This change is long overdue, and it materially improves the value proposition of the entry-level model.
On the M4 MacBook Air, 256GB of storage felt increasingly restrictive in 2025, particularly for users storing large photo libraries, project files, or running virtualisation software. Many UK buyers found themselves paying an extra £200 to upgrade to 512GB at purchase, effectively making the ‘real’ starting price closer to £1,199.
With the M5, 512GB is the new floor. Combined with the 2x faster SSD performance, this is the most tangible quality-of-life upgrade the average user will notice from day one. The maximum configurable storage has also doubled, rising from 2TB to 4TB, putting the MacBook Air on par with the MacBook Pro for storage headroom.
Storage upgrade summary: Base model now includes 512GB (up from 256GB), SSD read/write speeds are approximately 2x faster, and maximum storage doubles to 4TB. For UK buyers who would have paid extra for storage on the M4, the £100 price increase effectively pays for itself.
Design, Display, and Build Quality
Apple has made no changes to the MacBook Air’s physical design for this generation and that is not a criticism. The same precision-machined aluminium unibody introduced with the M2 in 2022 remains one of the best laptop chassis in the industry. It is thin, light, rigid, and beautifully finished.
- 13-inch: 30.41 × 21.5 × 1.13 cm, weighing 1.23 kg
- 15-inch: 34.04 × 23.76 × 1.15 cm, weighing 1.51 kg
- Display: 13.6″ and 15.3″ Liquid Retina LCD, unchanged from M4
- Colours: Sky Blue, Midnight, Starlight, Silver
- Ports: Two Thunderbolt 4 / USB-C, MagSafe 3, 3.5mm headphone jack
While Apple has not redesigned the chassis this year, the MacBook Air still remains one of the most refined laptop designs on the market. Other manufacturers are experimenting with new form factors, such as the Lenovo Rollable Screen Laptop that expands its display dynamically for multitasking.
The display remains a Liquid Retina LCD panel rather than OLED, a point of frustration for some prospective buyers. Reports indicate OLED will likely arrive in the MacBook Air after Apple refreshes the MacBook Pro with OLED technology, expected no earlier than late 2026 or 2027. For now, the existing display is excellent for its class: bright, colour-accurate, and perfectly suited to everyday creative work.
One notable upgrade is the charger. The M4 shipped with a 30W USB-C adapter; the M5 includes a 40W Dynamic Power Adapter capable of boosting to 60W. Note that UK retail boxes do not include a power adapter by default, Apple ships a USB-C to MagSafe 3 cable in all UK configurations.
Wi-Fi 7 and the Apple N1 Wireless Chip
The MacBook Air M5 becomes one of the first MacBooks to include Apple’s proprietary N1 wireless chip, previously debuted in the iPhone 17 lineup. This replaces the third-party wireless solution used in the M4 model and delivers meaningful practical benefits:
- Wi-Fi 7 (replacing Wi-Fi 6E): Multi-link operation for faster, more reliable connections
- Bluetooth 6 (replacing Bluetooth 5.3): Lower latency, improved audio, better accessory reliability
- Improved AirDrop and Personal Hotspot performance
- Better cross-device continuity features within the Apple ecosystem
For most UK users working in offices or home environments, Wi-Fi 7 is future-proofing rather than an immediate day-one gain, most UK broadband setups have not yet deployed Wi-Fi 7 routers at scale. However, Bluetooth 6 improvements may be felt immediately, particularly by users with AirPods Pro or other Bluetooth audio accessories.
MacBook Air M5 vs M4 UK: Should You Upgrade?
The MacBook Air M5 vs M4 UK upgrade question depends entirely on which model you currently own and what you use your laptop for.
If You Own a MacBook Air M4
The honest verdict: do not upgrade. The M5 is faster, but not in ways that will meaningfully change your day-to-day experience if you bought an M4 in 2025. Both machines share the same chassis, display, battery, and general feature set. Reviewers from Mark Ellis Reviews and Engadget concur that this is an iterative improvement, not a generational leap. Hold on for OLED or a significant redesign.
If You Own a MacBook Air M3, M2, or M1
This is where the MacBook Air M5 vs M4 UK comparison becomes very compelling because you are not really comparing M5 to M4. According to Six Colors, single-core performance gains grow to approximately 38% over M3, 57% over M2, and 75% over M1. If your Mac is more than two years old and you notice it slowing down, the M5 represents an excellent upgrade particularly given the 512GB storage floor and faster SSD.
If You Are Buying Your First Mac or Replacing an Intel Machine
The MacBook Air M5 is, simply, the best MacBook Air Apple has ever made. For UK buyers coming from an Intel MacBook or a Windows laptop, the performance difference will feel transformative. The M5 chips are exceptionally efficient, producing minimal heat despite the fanless design, and the claimed 18-hour battery life holds up well in real-world use. At £1,099, it remains outstanding value for a laptop at this performance level.
UK Pricing Breakdown: Is £1,099 Worth It?
| MacBook Air M5 Configuration | UK Price (2026) |
| 13-inch, M5, 16GB RAM, 512GB SSD | £1,099 |
| 13-inch, M5, 16GB RAM, 512GB SSD (Education) | £999 |
| 13-inch, M5, 24GB RAM, 1TB SSD | From ~£1,399 |
| 15-inch, M5, 16GB RAM, 512GB SSD | £1,299 |
| 15-inch, M5, 16GB RAM, 512GB SSD (Education) | £1,199 |
The £100 price increase over the M4 buys you double the storage (512GB vs 256GB), a 2x faster SSD, Wi-Fi 7 and Bluetooth 6, up to 4x better AI performance, and a meaningfully faster GPU. When weighed against what M4 upgraders previously paid for the 512GB storage tier alone, the M5’s £1,099 base price represents a reasonable rebalancing rather than a simple price hike.
MacBook Air M5 vs M4 UK – The Final Word
The MacBook Air M5 is one of the best ultraportable laptops of 2026, combining the new Apple M5 chip, faster SSD storage, and Wi-Fi 7 connectivity while still starting at £1,099 in the UK. It is faster across every benchmark, dramatically better at AI tasks, meaningfully faster in SSD performance, and ships with double the base storage that the M4 launched with.
The addition of Wi-Fi 7 and Bluetooth 6 via Apple’s N1 chip is the wireless standard this category deserved, and the new 40W charger is a practical improvement over the 30W unit in the M4 box.
For UK buyers asking whether the MacBook Air M5 vs M4 UK comparison justifies £1,099, the answer depends on where you are starting from. If you are already on the M4, wait. If you are on anything older or buying your first premium laptop, the MacBook Air M5 is the clearest recommendation in its class.
Bottom Line: The MacBook Air M5 is the best MacBook Air Apple has ever made. The 512GB storage base, faster SSD, Wi-Fi 7, and M5 performance gains make the £1,099 price the most honestly-valued entry point the MacBook Air has offered in years. For new buyers and upgraders from M3 or earlier, it is simply the right choice.
