The MacBook Air is Apple’s most popular laptop, but how much RAM you have makes a big difference. Older Intel-based Airs once shipped with just 4GB, while today’s M1 and M2 models start at 8GB of unified memory. If you’re wondering what that means for real-world use, here’s a clear breakdown.

📋 Quick-View RAM Comparison
💻 4GB MacBook Air (older Intel models)
⚡ Fine for email and light browsing only
🧠 Struggles with modern macOS and multitasking
🎯 Too limited in 2025
💻 8GB MacBook Air (M1/M2 baseline)
⚡ Smooth for browsing, office apps, and streaming
🧠 Handles light editing and daily work well
🎯 Best choice for students and everyday users
🔍 Why the 4GB MacBook Air Exists
Earlier Intel-based MacBook Airs often shipped with 4GB RAM as the base option. At the time, it worked fine for email, web, and writing papers. But macOS has grown heavier, and apps now use far more memory. Even opening a few browser tabs or running Zoom can cause slowdowns.
So, is 4GB MacBook Air enough today? Not really. It’s okay for very basic use, but for most people in 2025 it feels outdated.
🔍 Why 8GB Is the New Baseline
The 4GB RAM vs 8GB RAM MacBook Air debate ended once Apple switched to Apple Silicon. Every M1 and M2 MacBook Air starts with 8GB of unified memory, which is more efficient than the old Intel RAM.
That means 8GB on an M1 or M2 actually performs better than 8GB did on older Intel models. For daily use—browsing, streaming, video calls, and even light editing—it feels quick and reliable. For most students, office users, and casual owners, 8GB is the safe starting point.
🔍 Real-World Use Cases
- Students → 8GB works for assignments, research, and online classes. 4GB falls behind.
- Office users → 8GB handles documents, spreadsheets, and multitasking smoothly.
- Casual users → 8GB is smooth for browsing, Netflix, and email, while 4GB struggles even here.
