What you pay

The MacBook Air M3 is $1,499, the MacBook Pro M3 $2,099. Same M3 chip, $600 apart.

Sustained load

For everyday work they feel identical. The difference shows only under long, heavy load: the Air throttles after 10–15 minutes, while the Pro's active cooling holds speed. Video editing and long compiles are where the Pro earns its price.

Ports and portability

The Pro adds a third USB-C port and a second external display, and weighs 3.0 lb to the Air's 2.7. Unless you push the chip for stretches, the Air does the same job for less.
