If you’re weighing the MacBook Air M5 vs M4 in Bangladesh right now, you’re not alone. Walk into any MacBook shop in Dhaka and you’ll see both models sitting on the same shelf — unusual, since normally the old model disappears once the new one launches. Apple kept the M4 around at a lower price instead of retiring it, which means you’re not choosing “old vs new,” you’re choosing which one actually fits how you’ll use it.

This guide breaks down what’s genuinely different between the two chips, what hasn’t changed at all, and — using real BD pricing — which model makes sense for students, professionals, and creators.

What’s Actually New in the M5 Chip

On paper, the M5 and M4 look similar: both use a 10-core CPU built from 4 performance cores and 6 efficiency cores, and both offer 8-core or 10-core GPU options. Apple has renamed the performance cores “Super Cores” on the M5 to reflect internal architecture tweaks, but the core count hasn’t changed.

The real gains show up in three places:

• Memory bandwidth jumps from 120GB/s on the M4 to 153GB/s on the M5 — roughly a 28% increase, which matters most when you’re juggling large files or multiple demanding apps at once.
• CPU benchmarks put the M5 around 12% faster single-core and 15% faster multi-core than the M4 in independent Geekbench 6 testing.
• GPU and AI performance see the biggest jump — Apple rates the M5’s GPU up to 45% faster, with a dedicated Neural Accelerator built into each GPU core. For anyone running on-device AI tools, generating images locally, or working in Final Cut Pro or Blender, this is where you’ll actually feel the difference.

For everyday use — browsing, documents, video calls, streaming — most people will not notice this gap.

Storage, Speed, and Connectivity

This is arguably the more practical upgrade for most buyers. The M4 MacBook Air started at 256GB of storage, which fills up fast once you’re saving lecture recordings, project files, or a photo library. The M5 doubles the base storage to 512GB, and its SSD is noticeably faster too — read speeds of roughly 7GB/s, more than double what the M4 manages, which shows up when you’re copying large video files or exporting projects.

The M5 also moves up to Wi-Fi 7 and Bluetooth 6, a real jump over the M4’s wireless hardware if your home or office network already supports the newer standard.

Design, Display, and Battery: What Hasn’t Changed

If you’re expecting a redesign, there isn’t one. Place the two laptops side by side and you won’t be able to tell them apart — same aluminum unibody, same 13.6″ or 15.3″ Liquid Retina display at 500 nits with P3 wide color, same 12MP Center Stage camera, and the same four-speaker sound system. Weight is nearly identical too: 1.23kg for the M5 versus 1.24kg for the M4.

Battery life is unchanged as well, with both models rated for up to 18 hours of video playback on a full charge and the same 40W USB-C/MagSafe 3 charging.

MacBook Air M5 vs M4 Price in Bangladesh

Right now, MacBook Air M4 and M5 models in Bangladesh span roughly ৳95,499 to ৳303,999, depending on chip, RAM, and storage configuration. As a rough guide:

• The M4 sits at the lower end of that range and is the more affordable entry point into the MacBook Air line.
• The M5 starts higher — reflecting the doubled base storage and newer chip — and climbs further with 15-inch and higher-RAM configurations.

Since Apple discounted the M4 rather than pulling it from shelves, it’s now priced closer to what a “budget Air” should cost, while the M5 sits where the M4 used to be at launch.

Who Should Buy the M4, and Who Should Buy the M5?

Here’s how the MacBook Air M5 vs M4 decision breaks down by use case:

Choose the M4 if:

• You mainly use your laptop for browsing, documents, classes, or office work
• You want the lowest entry price into macOS
• You don’t rely on local AI tools, heavy video editing, or Blender/Final Cut-style workloads

Choose the M5 if:

• You want 512GB of storage without paying extra to upgrade
• You edit video, run local AI models, or do GPU-heavy creative work
• You want Wi-Fi 7 and the fastest SSD speeds available on the Air line
• You’re upgrading from an M1 or M2 Air, where the generational gap is large enough to actually feel
