I compared the M5 vs M4 MacBook Air: Is it worth $100 more?

Apple refreshed the MacBook Air with the new M5 chip, and on the surface, the upgrades are minor. You get the same ultra-thin design and subtle architectural gains. But after spending time with both the M5 and last year’s M4 models, I realized that Apple quietly refined the new model with some meaningful features.

So if you’re stuck choosing between the M4 and M5 MacBook Air, here’s the complete performance difference and benchmark comparison you need to know. So, you can easily decide if upgrading is worth or the M4 MacBook Air is still the smarter buy right now.

M5 vs M4 MacBook Air: Quick specs comparison

Here’s the reality stripped down to what Apple actually changed in the latest M5 MacBook Air and what stayed the same:

Feature	M4 MacBook Air	M5 MacBook Air
Chip	Apple M4	Apple M5
CPU	10-core	10-core (improved architecture)
GPU	Up to 10-core	Up to 10-core with Neural Accelerators
Memory bandwidth	~120GB/s	~153GB/s
Neural Engine	16-core	16-core
RAM	From 16GB	Starts at 16GB, higher configs
Storage (base)	256GB	512GB
SSD speed	Standard	Up to 2× faster
Connectivity	Wi-Fi 6E + Bluetooth 5.3	Wi-Fi 7 + Bluetooth 6
Battery	~18 hours claimed	Similar, slightly more efficient

Let me be blunt: if you’re expecting a visual upgrade, you’ll be disappointed.

Everything is identical from the thin aluminum shell, weight, 13.6-inch or 15.3-inch Liquid Retina display, keyboard, 12MP Center Stage camera, to the trackpad. For the first day, I genuinely forgot which one I was using.

The M4 feels great when you start. Fast, responsive, no complaints. But as the workload builds with more tabs, apps, and background processes, it starts to feel slightly slower.

The M5 doesn’t change the first impression. It holds its composure better. Animations stay smoother, and heat buildup is slightly more controlled.

Performance: Where I actually noticed a difference

If you open both laptops fresh and run a quick task, you won’t see any major difference. That’s why most comparisons get this wrong.

The M4 handles everyday tasks, like multitasking, browsing, occasional Photoshop, etc., well. But on the M5, I found app switching was slightly snappier, tabs loaded with less hesitation, and the system didn’t feel like it was juggling.

The difference was more prominent in heavier workloads like 4K video editing, running LLM, immersive gameplay, vibe coding, and Apple Intelligence features. According to Apple, M5 is 4x faster than the previous generation, thanks to its 4 super cores in the CPU. Moreover, the dedicated Neural Accelerators in the GPU made it match M1 Ultra’s performance.

You can see the power gap in the benchmark scores as well:

Core	M5 MacBook Air	M4 MacBook Air
Single core	4197	3763
Multi core	16997	14694

What mattered more to me was the SSD upgrade. Apple doubled the base storage to 512GB and improved speeds up to 2×. So, the files open faster, exports complete sooner, and large projects don’t choke the system.

Battery life: Apple’s numbers vs my reality

Apple claims similar battery life, and technically, that’s true. Both machines can handle all-day usage up to 18 hours under light workloads.

But real usage tells a slightly different story.

Under heavy multitasking:

• The M4 drains more aggressively
• The M5 holds efficiency better

I was able to squeeze out around 30-45 more minutes of battery time from the M5 during intense work. While you’re working unplugged, an extra hour makes a big difference.

Things I wish I knew sooner

The biggest mistake I made was expecting a dramatic upgrade. That’s not what the M5 is. This is a refinement upgrade.

• The M5 vs M4 MacBook Air performance difference isn’t obvious, but it accumulates. Over hours, days, and heavy workflows, the M5 just feels more stable.
• Storage matters more than you think. That jump to 512GB base (and faster SSD) is arguably more impactful than the chip itself.
• If your budget forces a choice, an M4 with more Unified Memory will outperform an M5 with less RAM in real-world use.
• The M5 isn’t about making your laptop faster today. It’s about making sure it doesn’t feel slow tomorrow.

Who should buy the M5 MacBook Air

If your workload demands a powerhouse, the M5 MacBook Air will pay off in the long run.

I’d recommend it for developers, content creators, and multitaskers who push their machines beyond casual use. The improved efficiency, faster storage, and better sustained performance make a noticeable difference over time.

It’s also the smarter choice if you plan to keep your laptop for several years. The improved memory bandwidth and AI capabilities make it more future-ready than the M4.

And honestly, if $100 doesn’t stretch your budget, this is one of those upgrades that quietly pays for itself.

Who should stick with the M4 MacBook Air

If your usage is light, like browsing, writing, streaming or office work, the M4 is still excellent. You won’t feel slower or limited and still save money.

Students, casual users, and anyone upgrading from older Intel or M1 Macs will find the M4 more than enough.

And if you’re budget-conscious, that $100 is better spent on RAM or storage upgrades, which will have a bigger impact on your daily experience.

Final verdict

The M5 MacBook Air is not a flashy upgrade. It’s a smart one with certain improvements that only show up when you actually rely on your machine with performance consistency, storage speed, efficiency, and future readiness.

Is the extra $100 worth it? Yes, if you prioritize longevity, sustained performance, and future-proofing. But if you just need a fast, reliable laptop for everyday tasks without breaking the bank, then the M4 would be more suitable for you.

If I were buying today, I would opt for the M5 MacBook Air.
