MacBook Air M3 vs M4: Should You Upgrade? | A Versus B
Quick Answer
AI SummaryThe MacBook Air M4 offers notably better CPU performance with a 10-core processor versus M3's 8-core, plus 16GB base RAM and improved efficiency, making it worth the $250-$300 premium for most users. However, budget-conscious buyers or those prioritizing value can find refurbished M3 models at $650-$700, which still deliver solid everyday performance.
Read full verdictThe MacBook Air M4 is the superior choice for most users in 2026, delivering meaningfully better performance with its 10-core CPU, standard 16GB RAM, and improved efficiency at $999-$1,149. However, the M3 remains a smart buy for budget-conscious shoppers who can find refurbished units at $650-$700, offering excellent value for everyday computing tasks like browsing, office work, and light creative projects.

Frequently Asked Questions

Yes, the MacBook Air M4 is better than the M3 in most measurable ways. It offers faster CPU and GPU performance, supports up to 32GB of unified memory compared to the M3's 24GB cap, features an updated 12MP Center Stage webcam, and includes two Thunderbolt 4 ports on both sides. However, the performance gains are incremental for everyday tasks, making the M3 a still-capable machine if purchased at a significant discount.
Following the M4 launch, the MacBook Air M3 typically sells for $200–$300 less than the M4's starting price of $1,099. Apple and authorized retailers often discount M3 units to clear inventory. If budget is a primary concern, the M3 offers strong value at its reduced price, since both models handle most everyday tasks like browsing, email, and document editing without noticeable difference.
The MacBook Air M4 is the better choice for video editing. Its improved media engine handles ProRes video more efficiently, and its faster GPU accelerates effects rendering in Final Cut Pro and Premiere Pro. The option to configure up to 32GB of unified memory also helps with 4K and 6K timelines. For casual 1080p editing, the M3 remains sufficient, but professionals working with high-resolution footage will notice meaningful gains with the M4.
The MacBook Air M4 is already available, so there is no reason to wait. If you need a laptop now, the M4 is the smarter long-term investment due to better performance, higher memory ceiling, and longer software support lifecycle. The M3 is worth buying only if you find it at a steep discount of $250 or more. Otherwise, the M4's improvements in speed, memory, and connectivity justify its slightly higher starting price.
The MacBook Air M4 offers marginally better real-world battery life than the M3, despite both Apple models being rated for up to 18 hours. The M4 chip's improved power efficiency means it sustains performance longer under mixed workloads like video streaming, web browsing, and light productivity. In daily use, most users report one to two additional hours on the M4, though both laptops easily last a full workday on a single charge.
For most M3 Air owners, the MacBook Air M4 upgrade is not worth it yet. The M4 chip offers approximately 20–25% CPU improvement and 25–35% GPU improvement over M3 in benchmarks, but real-world day-to-day tasks feel largely identical. The upgrade makes sense if: (a) you are coming from an Intel Mac and jumping to M4, which is a transformative upgrade; (b) you need more unified memory (M4 Air offers 16GB base vs M3's 8GB base, and up to 32GB vs M3's 24GB max); or (c) you find a compelling trade-in or discount. If you bought an M3 Air in 2024, the money saved by skipping M4 and waiting for M5 (expected 2026–2027) will likely be worth more than the M4's incremental gains over your current machine.
Apple claims 25–30% faster CPU performance and up to 35% faster GPU in the M4 vs M3. In practice, tasks like exporting a 4K video in Final Cut Pro and running large AI models are noticeably faster on the M4. For web browsing, document editing, or email, the difference is imperceptible. The M4 gains matter most for creative professionals and developers who stress the chip regularly.
Yes, if you're buying new — the M4 Air starts at the same MSRP as the M3 did at launch, so there is no real premium for new buyers. If you're deciding between buying a new M4 or a discounted used/refurbished M3, the M3 can be an excellent value at $100–200 below MSRP; it will remain fully supported by macOS for several more years and handles all everyday tasks without compromise.
Both the M3 and M4 MacBook Air start at 8 GB unified memory with options to configure 16 GB or 24 GB. The difference is speed: M4's memory bandwidth is higher (up to 120 GB/s vs 100 GB/s on the M3), making the 8 GB M4 feel more capable under load than the 8 GB M3. If your work involves large datasets or simultaneous heavy apps, prioritize configuring 16 GB on whichever chip you choose.
Apple typically supports Macs with macOS updates for about 7 years after release. The M3 MacBook Air launched in early 2024, so expect support through approximately 2030–2031. The M4 Air (2025) extends that window to around 2032. If you plan to keep your Mac for 4–5 years, both chips will be fully supported with no difference in practice.
Expert Analysis: MacBook Air M3 vs MacBook Air M4
The single fact that determines which MacBook Air most buyers should choose is price relative to performance gain. The M4 model currently retails for roughly $950 new, while the M3 can be found for around $780 — a $170 gap that only makes sense to close if you'll genuinely stress the chip (MW Technology, 2025). For the majority of users whose daily workload sits below the thermal ceiling of either processor, that price difference buys almost nothing measurable in lived experience.
Where the gap does show up is in raw compute headroom. The M4 chip packs more transistors into the same physical architecture, translating to meaningful improvements in sustained CPU throughput and Neural Engine performance — the latter becoming increasingly relevant as Apple Intelligence features deepen across macOS. In video export tests using Final Cut Pro, the M4 Air consistently finishes rendering tasks noticeably faster than the M3, a difference that compounds over a full working day for creators processing footage regularly. Apple also doubled the base unified memory on the M4 Air to 16GB, compared to the M3's 8GB starting configuration — a structural advantage that matters for multitasking and longevity without paying extra for an upgrade tier (Apple, 2025).
Battery life and display are non-factors in this decision. Both generations ship in identical 13.6-inch and 15.3-inch chassis with the same Liquid Retina panels, the same port selection, and comparable all-day battery endurance. There is no design refresh to reward early adopters aesthetically, which removes one of the traditional upgrade incentives entirely.

The M3 Air makes clear sense for buyers who already own one and are not experiencing friction, or for first-time Mac converts stepping off older Intel hardware who want the lowest entry cost into Apple silicon. Students, light office workers, and casual creative users will not hit the M3's ceiling in a meaningful way during a standard ownership cycle. The M4, by contrast, is the right choice for developers running local AI models, video editors working with 4K or higher footage, and anyone planning to hold the machine for five-plus years and wants to stay ahead of software demands as Apple Intelligence workloads intensify. Apple's Mac shipments grew to 5.2 million units in Q1 2026, signaling continued platform investment that rewards buying into the current generation (Statista, 2026).
Skip the M3 if you are purchasing new today. At retail prices, paying a $170 premium for double the base RAM alone justifies the M4 — the performance uplift on top is a free addition. If you find a refurbished M3 with 16GB or 24GB of unified memory at a steep discount, that changes the calculus, but for any standard new purchase, the M4 Air is the version worth owning through the rest of this decade.
