Just now realizing there's a difference between "MacBook Pro with M# chip" and "MacBook Pro with M# Pro chip". Was curious to see how my MBP with M4 Pro compared, and I saw it has 273 gb/s memory bandwidth compared to the MBP M6 (sans Pro)'s 170gb/s. Makes sense that "Pro" in the laptop model doesn't also describe the chip, but only if you remember that the non-pro "Macbook" line stopped in 2017 (which was the last time I went shopping for Apple laptops until buying the MBP4)

The "Pro" in MacBook Pro has slowly degraded to "it comes with a fan so that the chip can keep chugging when it gets a hard workload, unlike the MacBook Air where the chip will throttle since there's no fan".
Screen, ports too (to be fair I've used the HDMI port about 5 times, and the card reader never).
The base model chip on the Air is binned too - 8 GPU cores on the Air vs 10 on the Pro.
