Key Differences
-
The MacBook Air M4 has 8 GB more base memory
It’s a lopsided result (16 GB for the MacBook Air M4, 8 GB for the MacBook Air M2) and one of the main reasons to choose between them. Pro workloads like photo and video editing or virtual machines benefit most from the extra memory.
-
The MacBook Air M4 has 2 more CPU cores
It’s a small lead (10 versus 8), but it’s real, and it goes to the MacBook Air M4. Core types and clock speeds differ between chips, so core count is one indicator among several.
-
The MacBook Air M4 has up to 32 GB of memory
The spread here is large: 32 GB on the MacBook Air M4 versus 24 GB on the MacBook Air M2. Expect to notice it. For large datasets, virtual machines or heavy creative projects, the MacBook Air M4’s higher maximum is valuable.
