NEW YORK—None of the new Macs that Apple is announcing at its "Scary Fast" product event today look very different from the ones they're replacing on the outside, but the inside is another story. This is the first batch of Macs to include Apple's next-generation M3-series chips, and unlike past years, Apple is introducing multiple M3 performance tiers all at the same time.

The M3, M3 Pro, and M3 Max all share the same underlying CPU and GPU architectures, the same ones used in the iPhone 15 Pro's A17 Pro chip. Also like the A17 Pro, all M3 chips are manufactured using a new 3 nm process from Taiwan Semiconductor (TSMC). Let's dive into everything we know about the M3 family's capabilities, plus the differences between each performance tier.
