Gurman said it is “plausible” that at least the next 13-inch MacBook Air will be equipped with the as-yet-unannounced M3 chip, which will reportedly be manufactured based on TSMC’s latest 3nm process for improved performance. The current 13-inch model was released in July 2022 and is powered by the M2 chip, which is based on a 5nm process.

I would be really surprised to see the updated MacBook Air product line introduce the new M3 so soon. Why? The MacBook Pro is based on the M2. Even if people buy computers, not chips, it would send a weird signal to have an M3 product at the entry level while the Pro machines are using M2. The 3 nanometer process will probably help reduce heat dissipation, but the last time I checked, the M2 in the 13-inch MacBook Air doesn’t exhibit any problems, even when the machine is running at full processing power.

One possibility, though, is if the M3 chip really helps make a difference from an end-user perspective enough to entice users to upgrade. We’ll see soon enough. And I can’t wait to get my hands on the 15-inch version of the MacBook Air.
