MacBook Air M2 vs M4
Short answer: in MacBook Air M2 vs M4, the M4 is the better laptop and the safer long-term buy, mainly because every M4 Air starts with 16GB of memory, has a faster 10-core chip and supports two external displays. The M2 Air looks almost identical and is still quick for study and office work, at a noticeably lower price. Buy the M2 to save money; buy the M4 if you will keep it four years or more.

Price
The MacBook Air M2 starts well below the M4 on our list, and the gap is large enough to matter for most Pakistani buyers. The 15-inch versions follow the same pattern. Starting prices are listed on each model page.
Compare like with like: an 8GB M2 against a 16GB M4 is not a fair match. A 16GB M2 narrows the price gap, so check both before you decide.
Performance
The M2 has an 8-core CPU (4 performance and 4 efficiency cores). The M4 has a 10-core CPU (4 performance and 6 efficiency cores) on a newer design, so it is noticeably faster in both single-core and multi-core work. You will feel the gap in Xcode builds, large Lightroom exports, 4K video edits and when many apps are open together. For browsing, Office, Zoom and streaming, both feel fast.
Both are fanless, so long heavy exports slow down as the chip warms up. The M4 starts from a higher level and finishes such jobs sooner. The M4 GPU also adds hardware ray tracing, which helps the few Mac games and 3D apps that use it.
RAM: 8GB vs 16GB
This is the biggest practical difference. Most M2 Airs sold in Pakistan are 8GB models, although 16GB and 24GB versions exist. Every M4 Air starts at 16GB and goes up to 32GB.
8GB is fine for students doing documents and browsing. With Chrome tabs, Slack, Photoshop or Android Studio open together, an 8GB Mac starts using the SSD as memory and slows down. Apple Intelligence features also use memory. Since RAM can never be upgraded on a MacBook, the 16GB base of the M4 is a big part of its value.
External displays
The M2 Air supports one external monitor. The M4 Air supports two external monitors with its own screen still on. If you plan a desk setup with two monitors, for programming or trading, only the M4 does it without adapters and workarounds.
Battery, camera and design
Apple rates both at up to 18 hours of video playback and 15 hours of web browsing, so battery life is effectively the same. Both use the same thin, flat design with a 13.6-inch Liquid Retina display at 500 nits, MagSafe charging, two USB-C ports and a headphone jack, and both weigh about 1.24 kg.
The M4 upgrades the webcam from 1080p to a 12MP Center Stage camera that keeps you framed on video calls, and its ports are Thunderbolt 4. The M4 Air also added a new Sky Blue colour.
Software support and resale
Apple usually supports Macs with macOS updates for many years, and newer chips stay supported longer. The M4 is about three years newer than the M2, so it should receive updates and new features for longer, which matters if you plan to keep the laptop through a full degree or job.
Resale follows the same logic. Both models hold value well in Pakistan, but a 16GB M4 will be easier to sell at a good price in a few years than an 8GB M2. If you sell your laptop every two or three years, the M2's lower purchase price balances this out.

Who should buy which
- Students on a budget, writing and browsing: MacBook Air M2, ideally 16GB if you find one.
- Programmers, designers and photo editors: MacBook Air M4.
- Two-monitor desk setups: MacBook Air M4.
- Want a bigger screen: Air 15 M2 for value or Air 15 M4 for performance.
- Middle ground: the MacBook Air M3 sits between the two in price and speed but keeps the one-display limit with the lid open.
Verdict
If your budget allows, buy the MacBook Air M4. The 16GB memory, faster chip and dual-monitor support make it the model that will stay smooth longest. If the price gap matters more, the M2 Air is still a very good laptop for everyday work and gives the same design, screen and battery life.
