MacBook Air M5 versus M4: the new Air wins, but M4 owners should keep theirs

Apple made the MacBook Air meaningfully faster without making it meaningfully different. The M5 generation improves processor and graphics performance, base storage, wireless connectivity and configuration headroom, yet it preserves the same basic proposition as the M4: a thin, silent laptop with excellent controls, strong battery life, two left-side Thunderbolt ports and a 60Hz IPS display that looks increasingly modest beside the rest of the computer.

That split produces two different answers. A buyer replacing an Intel Mac, an aging Windows laptop or an older memory-constrained Air should generally choose M5. An M4 owner who already has enough memory and storage should close the upgrade tab. Email, documents, browsing, calls and ordinary coding will not feel transformed merely because benchmarks rise.

The older generation can still win on value, especially when an exact M4 configuration offers more memory than the M5 model being considered. The two M4 offers covered here complicate that argument, however. One omits its memory, storage, GPU, condition and warranty from the supplied record; the other promises an attractive 24GB/512GB specification but carries customer reports associated with refurbished stock, nonstandard accessories and cosmetic damage. A good chip generation does not make an ambiguous transaction safe.

This is not a contest between a good laptop and a bad one. It is a contest between a mature design and a faster version of that same mature design. The M5 is the better computer in isolation; the M4 can be the smarter purchase or the smarter machine to retain.

At a Glance

What changed, what did not, and what actually matters

The M5’s clearest technical advantage is speed. Independent testing of the 13-inch model placed Geekbench 6 single-core results a little above 4,100 and multicore results around 16,900 to 17,100, ahead of recorded M4 Air results. The 15-inch M5 produced a similar class of CPU result, while its 512GB SSD reached roughly 6.5GB/s in independent testing. Those figures matter for large file transfers, code builds, photo processing, short exports and applications that use the newer GPU accelerators.

They matter less when the workload spends most of its time waiting for a person to read, type or decide. Both generations are already extremely responsive in browsers, office suites, messaging applications and ordinary development tools. The M5 saves more time as tasks become heavier; it does not make an M4 feel obsolete while opening a document.

The performance lead does not repeal fanless physics

Both generations have no fan. They remain silent during every workload, an advantage in classrooms, shared offices, calls and recording spaces. Heat still accumulates under prolonged processor and graphics loads, so each machine eventually reduces power and speed.

A long M4 stress run showed a large decline from its opening processor frequency, with most of the reduction arriving during the first minute. The M5 improves how much work the Air can complete, but testing still found a substantial fall during repeated rendering and combined CPU-plus-GPU stress. M5 therefore moves the ceiling upward without removing it.

That distinction is easy to use. The Air suits workloads that burst, pause and finish: compiling a moderate project, editing photographs, exporting an occasional video or running a short local-AI task. Daily hour-long renders, repeated large builds, intensive 3D work and constant local inference belong on actively cooled hardware. Readers with those requirements should compare the Air with the MacBook Pro before paying for an overconfigured fanless machine.

The screen is the missed opportunity on both generations

Apple’s Liquid Retina panels remain crisp, color-capable and bright enough for normal indoor work. The larger 15.3-inch version provides genuinely useful room for spreadsheets, timelines and side-by-side documents, while the 13.6-inch panel keeps the computer compact enough for cramped tables and frequent travel.

Neither generation brings a high-refresh display, OLED blacks, mini-LED HDR or variable refresh. Scrolling is less fluid than on a 90Hz or 120Hz panel, dark scenes cannot match self-emissive displays, and the glossy surface is not ideal in harsh light. An M4 owner dissatisfied with the panel gains nothing by moving sideways to M5. A buyer who considers display quality a primary requirement should look at the 14-inch MacBook Pro M5 instead.

Memory can matter more than the chip badge

Sixteen gigabytes is a sensible floor for study, office work, mainstream programming, research and moderate creative use. Twenty-four gigabytes becomes useful when several demanding applications must coexist, development relies on containers or virtual machines, large photographs remain open beside other tools, or local AI workloads consume unified memory aggressively.

That gives the 24GB/512GB 15-inch M4 a legitimate path to victory over a 16GB/512GB M5. The M5 processor is faster, but it cannot compensate for a workload that exceeds available memory. Conversely, a browser-and-documents user gains little from 24GB and should not accept uncertain condition merely to acquire headroom that will remain idle. Our guide to choosing 16GB or 24GB of MacBook memory separates concrete need from vague future-proofing.

Wi-Fi 7 is useful future-proofing, not an upgrade mandate

M5 adds Wi-Fi 7 and Bluetooth 6, while M4 uses Wi-Fi 6E and Bluetooth 5.3. The newer standard can accelerate transfers to a compatible fast router, network-attached storage or local server. It cannot make a slower internet connection, older router or limited remote service run faster.

Buy M5 for Wi-Fi 7 when a suitable network already exists or the laptop is expected to remain in service through a network refresh. Do not replace an otherwise satisfactory M4 solely because its wireless badge is one generation older.

Battery life remains excellent on both sides

Controlled tests across both generations support a full working day under moderate use, with favorable video and browsing exercises often reaching the mid-to-high teens in hours. Heavy calls, maximum brightness, gaming, compiling, exports and local AI can shorten that substantially. The useful conclusion is not that one chip guarantees an exact number; it is that both Air generations offer excellent endurance when their batteries are healthy.

Condition changes the comparison. A used or refurbished M4 with an aged battery may lose the very advantage buyers associate with the Air. Ask for cycle count and maximum capacity, then verify both during the return window. A newer chip is not required for good battery life, but a good battery is.

The four listings, ranked with their catches exposed

The M5 models rank first because they combine clear configurations with the stronger generation. The M4 models follow because their hardware remains appealing but their supplied Amazon records introduce transaction risk. The 15-inch M4 ranks above the 13-inch M4 because its promised 24GB/512GB specification is concrete and potentially valuable, although it still requires condition and accessory verification.

The 15-inch M5 is the better Air when the laptop itself must be the desk.

Its 15.3-inch workspace, six-speaker system, 16GB memory and fast 512GB storage make split-screen productivity more comfortable without requiring a heavier MacBook Pro.

The broad footprint travels less gracefully, the Midnight finish shows fingerprints and the same 60Hz panel and sparse port layout remain.

Choose by the problem, not by the generation number

A short inspection list for either older Air

• Confirm whether the computer is new, renewed, refurbished, used or open box.
• Verify the reported chip, unified memory and storage in macOS before the return window closes.
• Check battery cycle count and maximum capacity rather than relying on an endurance claim.
• Confirm that Activation Lock, Find My and organizational management locks are absent.
• Inspect the display coating, corners, lid, underside, hinge, keyboard and ports in good light.
• Test MagSafe, both Thunderbolt ports, headphones, Touch ID, camera, microphones, speakers, Wi-Fi and Bluetooth.
• Check that the charger and cable are genuine, undamaged, correctly rated and appropriate for the region.
• Confirm warranty coverage, AppleCare eligibility, return terms and responsibility for return shipping.

The final call

The M5 MacBook Air is the right default purchase because it is faster, better specified at the base level and easier to recommend without qualification. Choose the 13-inch version when the computer moves frequently and the 15-inch version when its own display must carry the working day.

The M4 remains too good to replace merely because M5 exists. Keep one that performs well, holds enough data and reaches the end of the day. Buy one now only when its exact memory, storage, condition, battery, warranty and accessories survive scrutiny. In this comparison, the chip question is simple; the older listings are where judgment becomes necessary.

Specs & Screens did not handle or benchmark these four laptops. This comparison reconciles the site’s existing product reviews with the supplied Amazon listings, retained customer reports and independent test results, while treating different configurations and test methods as different evidence rather than interchangeable measurements.
