iPad Air M4 vs iPad Air M3: One Year Later, 50% More RAM

Apple refreshed the iPad Air just one year after the M3 model, which is unusually fast even for Apple’s increasingly aggressive update cycle. The iPad Air M4 brings meaningful upgrades — more RAM, Wi-Fi 7, and Apple’s own cellular modem — at the same $599 starting price. But is it enough to justify replacing a one-year-old tablet?

What Changed

Spec	iPad Air M4 (2026)	iPad Air M3 (2025)
Price	$599	$599 (discounted ~$499)
Chip	M4	M3
RAM	12GB	8GB
Wi-Fi	Wi-Fi 7 (N1 chip)	Wi-Fi 6E
Cellular	C1X (Apple)	Qualcomm
Storage	128GB	128GB
Display	11” LCD 60Hz	11” LCD 60Hz
Weight	462g	462g

The 50% RAM increase (8GB → 12GB) is the headline. The M4 chip brings ~30% faster performance, and the N1 wireless chip delivers Wi-Fi 7 with better range and lower latency. The C1X modem in cellular models is faster and more power-efficient than Qualcomm’s solution.

The RAM Upgrade Actually Matters

We noticed the difference immediately in Stage Manager. The M3’s 8GB was technically fine for running two apps side by side, but add a third — say Safari with a dozen tabs, Notes, and a messaging app — and background apps would reload constantly. The M4’s 12GB eliminates that frustration almost entirely.

In practice, this is the single biggest quality-of-life improvement. The M4 chip is faster on benchmarks, sure, but you won’t feel a 30% CPU improvement when scrolling through emails. You absolutely will feel apps staying alive in memory instead of refreshing every time you switch back to them.

For anyone using their iPad Air as a laptop replacement with a Magic Keyboard, the extra RAM transforms the multitasking experience from “good enough” to genuinely seamless.

Wi-Fi 7 and the C1X Modem

Wi-Fi 7 via the N1 chip sounds like a spec sheet flex, but there are real-world benefits. Connection stability in crowded environments — coffee shops, airports, lecture halls — is noticeably better. The M3’s Wi-Fi 6E was already fast, but the N1 chip handles interference and channel switching more gracefully.

The C1X modem in cellular models deserves attention too. Apple designed it from scratch, replacing Qualcomm’s solution. In our experience, it delivers more consistent signal strength in weak coverage areas and uses less battery doing it. If you’re buying the cellular model, the M4’s modem alone justifies the upgrade.

Should M3 Owners Upgrade?

No. The M3 iPad Air is still an excellent tablet that’ll last 4+ more years. The performance jump is incremental, and the 8GB RAM is adequate for current iPadOS tasks. Save your money and skip a generation.

Honestly, upgrading a one-year-old device almost never makes financial sense. The M3 Air will get iPadOS updates for at least five more years, and its performance ceiling is nowhere close to being reached by current apps. Unless the RAM situation is genuinely bothering you — and it might be if you’re a heavy multitasker — sit this one out.

Should Older iPad Owners Upgrade?

Yes, if you have an iPad Air M1 or older. The cumulative improvements — M4 chip, 12GB RAM, Wi-Fi 7, better multitasking — make a significant difference over two or more generations.

Coming from an M1 Air, you’re looking at roughly double the performance, 50% more RAM, a vastly better wireless stack, and a much faster cellular modem. The M1 Air was already showing its age with Stage Manager — apps would stutter during transitions, and background refresh was aggressive. The M4 handles all of that effortlessly.

If you’re still on a pre-M1 iPad Air (the A14 model from 2020), the upgrade is even more dramatic. That device won’t support future iPadOS features, and the performance gap is enormous.

New Buyers: M4 or Discounted M3?

The M3 is available discounted at $449-499. If the $100-150 savings matters, the M3 is still a great buy. But at full price ($599 vs $599), the M4 is the obvious choice — more RAM, better wireless, and one extra year of software support.

We would recommend the discounted M3 for one specific scenario: you’re buying an iPad as a media consumption device — streaming, reading, casual browsing — and you don’t plan to push multitasking hard. For that use case, 8GB is fine and the $100-150 savings is better spent on a good case and an Apple Pencil.

For everyone else — students, professionals, anyone using Stage Manager — pay the full $599 and get the M4. The RAM and wireless upgrades will pay dividends over the tablet’s lifespan.

Verdict: New buyers get the M4. M3 owners stay put. Check our iPad Air M4 review for the full assessment.
