The M4 architecture introduces hardware-accelerated ray tracing to the 13-inch form factor, a stark contrast to the dual-core limitations of 2019-era machines. Buyers must decide between spending approximately $350 for basic browsing capabilities or investing $1099 for a device built for the next 5 years.
- M4 neural engines process AI workloads 40% faster than the M3 series.
- Entry-level configurations now include 16GB RAM, eliminating the 8GB swap file bottleneck.
- Legacy Intel drives limit transfer speeds to 500MB/s compared to 6GB/s on modern NVMe SSDs.

Apple’s 2025 release cycle introduced the M4 chip to the Air lineup, establishing 16GB unified memory as the new baseline standard. This hardware refresh promises a 1.5x graphics performance boost over M2 predecessors, challenging the value proposition of renewed Intel Core i5 units often found under $400. We examine whether the price gap of $700+ translates to necessary daily efficiency.
Detailed Performance Analysis
Choosing between these devices requires understanding the generational leap in processing power. The M4 chips utilize a 3-nanometer process that packs 28 billion transistors, whereas the older Intel i5 relies on a 14-nanometer lithography. This physical difference results in the M4 delivering 18 hours of video playback, nearly double the 10-hour rating of the 2019 model.
Apple MacBook Air 13-inch M4 (512GB)
The Highs
- 18-hour streaming runtime beats x86 laptops by a 6-hour margin.
- 500 nits brightness combats glare in outdoor environments.
The Lows
- Supports only 1 external monitor up to 6K resolution.
- MagSafe cable length is fixed at exactly 2 meters.
Who is this for?
Photography Students
512GB SSD holds 15,000+ RAW images vs 7,000 on smaller drives.
The 512GB configuration is the sweet spot for longevity, offering write speeds of 4,000 MB/s which significantly reduces application launch times. Unlike the Midnight finish which shows smudges, the internal hardware is robust, though users should note the 60Hz refresh rate lacks the fluidity of ProMotion displays.
Apple MacBook Air 15-inch M4 (24GB)
The Highs
- The M4 chip delivers a significant performance leap over Intel processors while maintaining up to 18 hours of battery life.
- The 15.3-inch Liquid Retina display offers a crisp 2880-by-1864 native resolution for professional-grade visual clarity.
The Lows
- A total weight of 1.51 Kilograms makes this 15-inch model noticeably heavier than the traditional 13-inch MacBook Air.
- The $1168 MSRP places this laptop at a much higher price point compared to budget-friendly legacy Intel i5 alternatives.
Who is this for?
Full-Stack Developers
24GB RAM allows running a local database and IDE simultaneously without lag.
This 15-inch model bridges the gap between portability and screen real estate. Weighing 1.51kg, it remains portable but provides enough thermal mass to sustain peak performance for 10 minutes longer than the 13-inch chassis before throttling.
Apple MacBook Air 13-inch M4 (256GB)
The Highs
- The M4 chip provides a massive efficiency boost over legacy Intel i5 processors by utilizing its advanced 8-core CPU architecture.
- Users can enjoy up to 18 hours of battery life while benefiting from the vibrant 500 nits Liquid Retina display.
The Lows
- An MSRP of $1378 makes this 13-inch model significantly more expensive than many competing Windows laptops with similar storage capacities.
- Despite its high performance, the inclusion of only two Thunderbolt 4 ports limits connectivity for users with multiple wired peripherals.
Who is this for?
Administrative Assistants
Handles 50+ browser tabs efficiently thanks to 16GB memory.
While the storage is tight, the base M4 Air offers the most accessible path to Apple Intelligence features. The Silver finish is particularly practical, hiding micro-scratches that appear after 6 months of bag travel better than darker anodization.
Apple MacBook Air 13-inch (Intel i5)
The Highs
- Classic wedge design tapers to 0.16 inches at the thinnest point.
- 720p FaceTime camera suffices for casual 30-minute Zoom calls.
- The 13.3-inch Retina display features 4K resolution for high-definition video playback and increased screen real estate compared to 1080p panels.
The Lows
- Dual-core 1.6GHz processor lags 80% behind Apple Silicon speeds.
- 128GB drive leaves under 20GB free after essential OS updates.
- Integrated Intel UHD Graphics 617 shares the 8GB of DDR3 memory and lacks dedicated VRAM for 4K video editing or 3D rendering.
Who is this for?
Kiosk Displays
Low $350 cost minimizes risk for public-facing 24/7 signage.
This renewed unit represents the end of an era. Its Butterfly keyboard mechanism has a travel distance of just 0.55mm, which some typists find jarring compared to the 1mm Magic Keyboard on newer units. It should only be considered for strictly light tasks.

Mistakes to Avoid When Buying
1. Buying an Intel i5 Air with only 8GB of RAM
Why it hurts: Legacy Intel models lack unified memory, causing severe lag and 'beach-balling' when multitasking between modern browsers, Zoom, and productivity apps.
Do instead: Get the M4 Air. Its unified memory architecture handles intensive workloads more efficiently than older Intel chips, even at lower total RAM capacities.
2. Expecting sustained peak performance from Intel's fan-cooled chassis
Why it hurts: Intel i5 processors generate excessive heat in the thin Air frame, triggering thermal throttling that slashes your processing speed within minutes of use.
Do instead: Switch to the M4 Air. It uses a fanless design that stays cool and maintains consistent speeds during long video edits or heavy spreadsheet work.
3. Choosing legacy Intel hardware to save money upfront
Why it hurts: Intel Macs face a shorter remaining lifecycle. You will lose access to new macOS versions and critical AI features like Apple Intelligence much sooner.
Do instead: Invest in the M4. The longer support window and superior power efficiency result in a lower total cost of ownership over the next five to seven years.
