1. Performance and Chip Comparison

Apple’s MacBook Air lineup is powered by its custom-designed silicon chips: the M1, M2, and M3. Here’s how these chips compare:

M1 Chip

• Architecture: 5nm process, 8-core CPU (4 performance + 4 efficiency cores) and up to 8-core GPU.
• Performance: Outstanding efficiency and performance for basic tasks like web browsing, video streaming, and light photo editing. Suitable for most general users.
• Memory Bandwidth: 68.25 GB/s.
• Unified Memory: Configurable up to 16GB.
• Key Features: Great battery life (up to 18 hours), very quiet due to its fanless design, and excellent for casual use.
• Limitations: Lags behind in performance for intensive workloads like 4K video editing or complex multitasking.

M2 Chip

• Architecture: Enhanced 5nm process, 8-core CPU (similar configuration) with an improved 10-core GPU option.
• Performance: 18% faster CPU performance and up to 35% better GPU performance compared to the M1. Great for casual creatives and light professional work.
• Memory Bandwidth: 100 GB/s (47% faster than M1).
• Unified Memory: Configurable up to 24GB.
• Key Features: Improved hardware acceleration for ProRes and HEVC encoding/decoding. Better for handling tasks like video editing and gaming.
• Limitations: Still not a powerhouse for demanding professional workloads.

M3 Chip

• Architecture: First MacBook Air chip built on the 3nm process, offering significant efficiency and performance gains.
• Performance:
  • CPU: Up to 30% faster than the M2.
  • GPU: Next-gen architecture for 3D rendering, machine learning, and gaming, with up to 40% faster performance.
• Memory Bandwidth: Estimated 125 GB/s (rumoured improvement).
• Unified Memory: Configurable up to 24GB or more (depending on the model).
• Key Features: Enhanced AI processing capabilities, better thermal management, and significantly improved battery life.
• Limitations: Early adoption premium price.

2. Display and Design

Apple’s MacBook Air lineup has seen changes in design and display quality across generations.

M1 MacBook Air

• Display: 13.3-inch Retina Display with 2560×1600 resolution.
• Design: Classic wedge-shaped design, lightweight (2.8 lbs/1.29 kg).
• Notable Features: Wide colour (P3), True Tone, and bright display (400 nits).

M2 MacBook Air

• Display: 13.6-inch Liquid Retina Display with 2560×1664 resolution. Slightly larger and brighter (500 nits).
• Design: New flat-edged design, inspired by the MacBook Pro. Lighter at 2.7 lbs (1.24 kg).
• Notable Features: Supports 1 billion colours, slimmer bezels, and a notch for the 1080p webcam.

M3 MacBook Air

• Display: 13.6-inch or 15.3-inch Liquid Retina Display with even better colour accuracy and brightness (potentially 550 nits).
• Design: Continuation of the M2’s sleek flat design. Same lightweight profile.
• Notable Features: HDR support, ProMotion (adaptive refresh rate up to 120Hz), and improved anti-reflective coating.
